2012 presentation on Innovative Business / University Partnership: The Safer Plasticizer Assessment Project - Project for the Green Chemistry & Commerce Council (GC3)
What Are Solutions For the Non-Recyclables That Our Industry Generates?Stephanie Elton
The following powerpoint presentation was shared at a Printing Industries of Northern California (PINC) webinar.
Channeled Resources Group provides solutions for both manufacturers and consumers of coated, treated, and laminated papers & films. We understand that companies need creative ideas and, particularly in today's economy, cost savings at both ends of the supply chain. Doing business should be simple and improve your company's bottom line.
CRG - Global Solutions is a recycler of both traditional and non-traditional papers. Our specialty is in processing roll stock and silicone coated release liner. We offer competitive pricing making us the ideal one-stop shop for your recycling needs.
Our niche is purchasing silicone-coated paper for repulping. We even buy discarded liner left behind from high-speed machine applicators.
Plastics have woven their way into our daily lives and now pose a tremendous threat to the environment. Over a 100 million tonnes of plastics are produced annually worldwide, and the used products have become a common feature at over flowing bins and landfills. Though work has been done to make futuristic biodegradable plastics, there have not been many conclusive steps towards cleaning up the existing problem. Here, the process of converting waste plastic into value added fuels is explained as a viable solution for recycling of plastics. Thus two universal problems such as problems of waste plastic and problems of fuel shortage are being tackled simultaneously. In this study, plastic wastes (High density polyethylene) were used for the pyrolysis to get fuel oil that has the same physical properties as the fuels like petrol, diesel etc. Pyrolysis runs without oxygen and in high temperature of about 300°C which is why a reactor was fabricated to provide the required temperature for the reaction. Converting waste plastics into fuel hold great promise for both the environmental and economic scenarios. Thus, the process of converting plastics to fuel has now turned the problems into an opportunity to make wealth from waste. The hazards of plastic waste is well known to us. The conversion of oil from plastic has dual benefits. First of all the oil produced can be used as a fuel for domestic purposes and also in vehicles and industries when further refined. Secondly the various types of pollution caused due to waste plastics can be minimized. Plastic in the first place is manufactured from natural gas specifically from ethane which is a constituent of natural gas. Therefore the waste plastic can be converted back into it. For the process of conversion a machine can be used which will heat the plastic to a temperature so that it melts and does not burns.
Production Fuel From Waste Plastic By Pyrolysis (Theoretical part)Alitek97
In our experiments, commercially available shredded plastics were procured and washed before pyrolysis. Pyrolysis it is one of the most favorable and effective disposing methods, the process is an environmentally friendly and efficient way to eliminate the effect of plastic. Pyrolysis is the thermal degradation of solid wastes at high temperatures (250- 325℃) in the absence of air (and oxygen). The main process given below:
1. Identification of waste plastics. (PE/PP/PS/LDPE/HDPE)
2. Crash and cut the plastic for the pyrolysis process
3. Condensation of the gas to obtain raw fuel.
4. Collect the sample and perform tests to identify the kinds of fuel produced.

Speech On Electronic Waste
Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling or disposal are also considered as e-waste. With advancements in the electronic world almost occurring on a day-to-day basis and increased availability of products to the public, it is not surprising to see a staggering increase in the generation of electronic wastes over the past decade. The e-waste now represents the biggest and fastest growing manufacturing of wastes with as high as about 40 million tons a year at the global level. All these thing leads to increase in E-waste generation in the country. Electrical and electronic equipment contain different hazardous materials which are harmful to human health and the environment, if not disposed of carefully. Due to the lack of awareness for e-waste recycling in emerging economies, innovation hubs and centres of excellence have not yet been established. This has leads to the requirement of a proper disposal and recycling system so that environmental pollution and health hazard is reduced. We have tried to give information in this book which will help in minimizing this ever growing problem. Today the electronic waste recycling business is in all areas of the developed world a large and rapidly consolidating business. This recycling is done by sorting, dismantling, and recovery of valuable materials. This diversion is achieved through reuse and refurbishing.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

3. Abstract
Several years ago, the electronics supply chain was making substantive progress in
establishing programs and partnerships to demonstrate the recovery, identification and sorting of
plastic from electronic equipment; and making inroads in the design community to gain
acceptance of recycled-content resins in new products. Many of these entrepreneurial efforts hit
major roadblocks due to the lack of consistent, quality supply and insufficient demand.
Technology is no longer the major challenge. Recyclers and equipment manufacturers have
demonstrated recovery processes that achieve high quality recyclate that can even meet the
demanding specifications for cosmetic parts in electronic applications. Industry now faces the
economic, institutional and political realities of making plastics recycling work.
2
4. I. Background
Recycling of electronic equipment is on the rise in the United States, fueled by
international and US regulatory developments and heightened interest in managing both the
asset value and waste stream created by the growing use of electronic equipment. Waste
management objectives target both the hazardous constituents in electronic waste and waste
diversion goals.
Electronic product recovery and recycling directives have been on the international
agenda for several years, most notably in Europe and Asia. In 1998, the European Union raised
the stakes with its draft proposal on electronic waste with stipulations on new product design,
including restrictions on the use of heavy metals and requirements for the use of recycled plastic
in new products. This directive is certain to have a "ripple effect" in the US. At the same time,
regulatory activity in the US has picked up with several states actively pursuing electronic waste
policies. Most notably, a ban on the disposal of cathode ray tubes (CRTs) is slated to take effect
July 1, 1999 in Massachusetts.
Electronics recycling creates a new and growing plastics waste stream. As shown in
Table 1, plastics in electronic equipment range from approximately 10 to 50 percent of materials
by weight. [1] Of the materials found in electronics, plastics have the highest intrinsic value,
according to several analyses. [2][3] Despite their prevalence in the electronics waste stream and
their inherent value, however, plastics are the least recycled material.
This study addresses the recycling of engineering thermoplastics (ETPs) in electronics. It
analyzes the dynamics of the plastics and electronics supply chain to identify successes, barriers,
and opportunities in plastics recycling and use of recycled content in electronic equipment, with
a focus on computers. The purpose of the research is to illustrate the potential for voluntary
cooperation among companies in the supply chain to recover and recycle engineering
thermoplastics in lieu of mandated producer responsibility.
This analysis is based on interviews with over 50 companies in the supply chain,
including resin suppliers, compounders, molders, equipment manufacturers, electronics
recyclers, plastics processors, and end use markets, in addition to available literature and
electronic data. Figure 1 provides a schematic of the supply chain. Interviews were conducted
between November 1997 and November 1998. Participating companies are listed in the
Acknowledgements.
II. Extended Product Responsibility in the US
Extended product responsibility (EPR) is an emerging principle for pollution prevention
in which the key players in the chain of commerce take appropriate responsibility for the
environmental impacts of the product throughout the lifecycle, including upstream impacts
associated with material selection and product design and downstream product disposal and
recycling. Ideally, EPR results in the sharing of responsibility for ameliorating environmental
impact among material suppliers, product manufacturers, distributors, users, recyclers, and

disposers, with the greater degree of responsibility resting with those actors in the product chain
most able to influence environmental impacts cost-effectively. EPR can be applied by industry
voluntarily or influenced by government requirements (e.g., purchasing preferences, product
take-back mandates.) [4]
In its 1996 report, Sustainable America, the President’s Council for Sustainable
Development (PCSD) endorsed the principle of extended product responsibility as a means to
"identify strategic opportunities for pollution prevention and resource conservation" throughout
the life cycle of a product. US EPA is encouraging voluntary, shared responsibility within the
product chain as an alternative to “extended producer responsibility”. Extended producer
responsibility, as currently applied to a variety of products in Europe and Asia, mandates the
central involvement and financial responsibility of producers in non-traditional functions,
such as the collection and recycling of electronics. While other links in the product chain, such
as retailers, may also be required to accept new responsibilities, the greatest responsibility, as
well as accountability, lies with producers.
Although EPA has not embraced "Euro-style" producer responsibility, it shares many of
the same goals, as defined by the Organisation for Economic Co-operation Development
(OECD):
• to reduce waste generation and increase recycling;
• to reduce the financial burden of local governments for waste management; and
• to give incentives to producers to design and manufacture products that result in less waste
and are more recyclable.[5]
4
6. In contrast to producer responsibility, EPA believes in shared responsibility that places
greater -- but not sole -- responsibility on producers. For example, product design and creating
markets are clearly within the purview of producers. EPA also seeks voluntary efforts, not
mandates. Voluntary initiatives would seek to tailor solutions based on an understanding of the
unique attributes of a product system, and engage the supply chain in collaborative solutions
spurred by "enlightened self interest". Benefits to the supply chain might include lower costs,
procurement preferences, preemption of mandates, and harmonization across states. [5]
III. Plastics Use in Electronics
Worldwide resin sales to the electronics industry generated $933 billion in revenues for
the plastics industry in 1996. Sales are expected to increase by over 40 percent in 1999. [6] In
1996 the US electrical and electronic industry consumed over 3 billion pounds of plastic, or 4.0
percent of the total plastics consumed in the US. [7] Within the electronics industry, the
computer and communications markets consumed the highest volume of resins. [6]
On average, plastics account for approximately 19 percent (by weight) of electrical and
electronic (E&E) equipment. [1] Table 1 provides a breakdown of the average plastic content of
E&E equipment in Western Europe in 1995. Several pilot municipal collection programs in the
US documented the proportion of plastics in the residential electronics waste stream at 33
percent for diverse electronic equipment [8] and 16 percent for computer equipment. [9]
Table 1: Average Plastic Content of E&E Equipment Western Europe 1995 [1]
Equipment % Plastic
Telecommunications 58%
Small Appliances 35%
Brown Goods 26%
Wire and Cable 25%
Large Appliances 21%
Computers 16%
Office Equipment 11%
Medical Equipment 3%
Table 2 shows the breakdown of resins used in E&E markets in North America. These
six resins and their blends account for 84 percent of total resin consumption in E&E equipment,
not including cable and wire. [10] The major resins used in the manufacture of computer and
electronic housings, include: acrylonitrile butadiene styrene (ABS), ABS/polycarbonate (PC)
blends, high impact polystyrene (HIPS), polycarbonate (PC), polyvinylchloride (PVC), and
polyphenylene oxide (PPO). Fire retardant grades are used in some applications.

7. Table 2: Resins in E&E Equipment in NA [10]
Resin % Total Resin
Polystyrene 31%
ABS 16%
Polypropylene 13%
Polyurethane 10%
Polycarbonate 9%
Polyamide 5%
Manufacturers choose specific resins to meet product performance requirements such as
impact strength, thermal stability, shock absorption, aesthetics, flame retardancy and costs.
Resin usage changes over time with product mix (e.g., mainframes to desktop to portable
computers), technology innovation (e.g., thin wall technology), the introduction of new resin
blends, and, in some cases, requirements of standards organizations (e.g., flame retardancy). One
major computer manufacturer, for example, uses polycarbonate in portable products for its
durability, while using PC/ABS in desktop models.
Current trends in resin use will impact end of life equipment recycling in 8-10 years, and
the potential for reintroduction of recyclate into new equipment. For example, in this
increasingly competitive industry, OEMs are choosing lower cost resins, where possible. One
trend is in the replacement of ABS with HIPS, a lower cost resin. HIPS has traditionally been the
material of choice for television housings, but currently it is eroding the market for ABS in
business machines. [11] Pressures to eliminate halogenated flame retardants and design
products for recycling have led to the use of metal shieldings in computer housings. This allows
OEMs to shift from ABS/PC, which is free of halogenated flame retardants, to lower cost ABS
and HIPS.
IV. Supply Chain Analysis
Prior research indicated that industry was making substantive progress in establishing
new programs to demonstrate the recovery, identification and sorting of plastic casings from
computers housings, photocopiers, and other office equipment; and making inroads in the
design community to gain acceptance of recycled-content resins in new product. [4][12] When
companies in the plastics supply chain were approached for this project, it came as quite a
surprise to learn that many of the entrepreneurial efforts had hit major roadblocks and fizzled
out, or that the companies decided for various reasons not to pursue plastics recycling.
Below is a brief summary and observations on the initiatives taken by the supply chain to
recycle engineering thermoplastics, and incorporate recycled content into new product.
6
8. A. Resin Suppliers
Resin suppliers were involved early on in the promotion of recycled resins, then backed
off due to lack of sufficient demand from OEMs, supply issues and business priorities. Several
suppliers continue to offer limited selection of recycled-content products in some markets.
Major prime resin suppliers in the US did not witness a strong, persistent market demand
for recycled resins to warrant investments in developing this business. OEMs expressed interest
to resin suppliers, but only if recycled resins could provide significant cost savings compared to
virgin without compromising quality. For the most part, resin suppliers could not (or were not
willing to invest the resources) to meet these requirements.
Resin suppliers are invested in prime production and feedstreams. Prime resin is there
core business. Recycled resin products represent a new business and a challenge to develop new
sourcing channels that provide consistent, quality product to customers. In addition, some resin
suppliers question whether it makes sense for them to be in the recycled resin business.
Through organizations such as the American Plastics Council (APC), prime resin
suppliers have been instrumental in the development of technologies for the identification and
sorting of plastics, and thus, helping to build a recycling infrastructure.
B. Compounders
Several specialty compounders (or second tier suppliers) have stepped up to fill the void
in supply of recycled-content resins. These companies are developing sourcing channels and
quality assurances such as UL certification for recycled-content resins. To date, however,
sourcing of plastic scrap is primarily from clean, post-industrial feedstreams such as
manufacturing scrap and compact discs, in addition to post-consumer water bottles. Only small
quantities of recovered post-consumer electronic equipment make their way back into new
electronic products, principally due to quality assurance concerns and previous use of now
restricted substances (e.g., halogenated flame retardants) in resins. In addition, most efforts
focus on higher-priced resins such as PC and PC/ABS. With these higher-priced resins,
compounders can cover their sourcing and processing costs, while offering a competitively-
priced product. The potential cost savings in the purchase of recycled resins can range from 10-
30 percent.
C. Molders
For molders, recycled-content resins appear to present no major processing issues. As
with the introduction of any new feedstream, processing parameters must be developed to match
the material characteristics and mold design, and then tweaked for optimum performance.
Despite the ease of use, the molders of electronic equipment in this study noted that they use a
limited volume of recycled-resins in their operations. Molders fulfill their customer's
requirements, and in the case of recycled content, their customers specify little recycled-content
resins. Regulatory constraints (e.g., FDA requirements), a lack of market drivers, and the
7
9. perception of design engineers that recycled resin is inferior were cited as possible reasons. This
last point is not surprising since some OEMs are even reluctant to use internal regrind in the
molding of parts.
D. Equipment Manufacturers
OEMs across the board have made significant progress in product design for disassembly
and recycling to facilitate future plastics recycling efforts. These design efforts include, for
example, the use of fewer types of plastics, coding plastic parts for material identification, the
use of molded-in finishes, and the elimination of metal coatings for electromagnetic shielding.
[4][13].
Numerous OEMs, including IBM, Xerox, and Hewlett Packard, have proven the
performance of recycled-content resins in cosmetic applications and internal parts. However,
many early efforts to incorporate recycled-content resins hit the supply "wall" due to
uncertainties about quantity, quality assurance, and cost. As a result, several OEMs embarked
on initiatives to remedy these supply challenges, including the development of in-house plastics
processing programs and working in conjunction with suppliers and competitors to better
understand and improve the supply of recycled resins and to develop alternative end use
markets.
While some OEMs have backed off from plastics recycling due to supply issues, other
OEMs, most notably IBM, have continued their commitment and through their determination
have successfully incorporate recycled-content into new products. In 1998, IBM introduced the
first computer that uses 100% recycled resin (PC/ABS) in all major plastic parts for a total of
3.5 pounds of resin per product. [14] One major contributor to IBM's success was the
establishment of corporate-wide goals for the use of recycled plastic. Several other OEMs
note that they have introduced products with recycled-content into limited markets, such as
Europe. To be a realistic option, most OEMs agree that recycled-content cannot compromise
performance and must be available at an equal or lower cost.
E. Electronics Recyclers
Plastics are definitely the "problem child" in electronics recycling. Today, recyclers must
deal with products that are 10 years or older, complete with undesired characteristics such as
resin variety, incompatible plastics adhered to each other, contamination (e.g., finishes, metal
inserts), and no material coding of parts. Electronic recyclers for the most part rely on manual
identification and sorting techniques. As a result of older products and current processing
capabilities, the predominant disposal route for plastics is incineration or landfill. This should
change as improved designs reach the end of life.
Some electronics recyclers are relying on alternative markets such as export markets.
Export markets are able to manually process electronic plastics at lower cost due to less-
expensive labor rates. In Massachusetts, a popular market for mixed plastic resins from end-of-
8
10. life electronic equipment is asphalt paving products. [15] Several other newly emerging markets
such as flooring products hold promise as well.
F. Plastics Processors
Plastics processors are a diverse "group" of companies. Many plastics processors only
accept single resin materials with little or no contamination, while others accept mixed
electronic scrap and other durables. Plastics processors can perform just a few or a variety of
services including material identification, grinding, sorting, metals separation, cleaning, paint
removal, reformulation and extrusion (i.e., pelletize). Automated plastics identification and
sorting technology that achieves high purity recyclate is available at a limited number of
processors across the US. Research and development efforts continue to improve the efficiency
and economics of handling mixed electronic waste streams.
V. Market Applications
Market applications for recycled engineering thermoplastics from used electronic
equipment identified in the course of this project are shown in Figure 2. Closed-loop and open-
loop applications were identified for resins of different quality. On the one extreme is asphalt
paving products which utilize mixed plastic scrap, including engineering and commodity grade
resins. On the other extreme is the proven performance of high quality, single resins in new
housing applications.

11. VI. EPR for Electronic Engineering
The electronic product chain must work together to increase the recycling of engineering
thermoplastics. It is clear from progress to date that no one link in the chain can accomplish the
task alone. Table 3 applies the principles of extended product responsibility to suggest a model
of shared responsibility for the electronics supply chain. It proposes roles that are within the
jurisdiction of each organization, but an enhancement and appropriate extension of current
functions.

12. The supply chain analysis revealed issues in both supply and demand for recycled
engineering thermoplastics, creating what many observers in the industry characterize as a
"chicken and egg" situation. Both resin suppliers and equipment manufacturers tested the
markets, and most pulled back. As a result, commitment to recycling on the part of OEMs and
resin suppliers appears to be the most pressing obstacle to further progress. For this reason, an
EPR framework for the electronics supply chain needs to simultaneously address these two
major issues 1) assurance of adequate volumes of consistent, quality supply; and 2) creating
market opportunities and demand for the use of recycled resin. With strong market demand for
recycled resins, the collection and processing infrastructure should grow and mature to meet
market requirements.
Technology does not appear to be the major obstacle to plastics recycling. Much
progress has been made over the last several years in identification, sorting, processing and use
of recycled-content resin. Investment in available technology that can identify and sort mixed-
resin, post-consumer electronics stream, however, is an issue. Such investments are difficult to
justify or maintain without assurances that markets will utilize and be willing to pay the price for
the recycled resin.
It is very possible that European pressures to incorporate recycled content in new
products may drive some companies to further their commitment to plastics recycling, similar to
the flurry of design and recycling activity stimulated by early European
product take back proposals. The European Union second draft Proposal for a Directive on
Waste from Electrical and Electronic Equipment (July 1998) requires new electrical and
electronic equipment to contain at least 5 percent recycled plastic by January 1, 2004. Proposed
recycling rates for computer equipment is a minimum of 70 percent by weight, while equipment
containing CRTs must be recycled at a minimum rate of 90 percent.
Similar proposals for automobiles are driving changes in the US automobile industry.
Daimler Chrysler launched a new policy in December 1998 to require plastics parts supplier to
provide at least 20 percent recycled content by weight by the year 2000. By 2002, the
percentage increases to 30 percent. The new standard requires that recycled-content parts not
come at the expense of cost, quality, weight, delivery or performance. This new policy is a
response to European pressure to make cars more recyclable, combined with DaimlerChrysler’s
belief that recycled content can be economically advantageous. [16]
