poster presentation on recycling of plasticMah Noor
This document discusses plastic recycling. It notes that plastic takes a very long time to decompose, from 200+ years for some plastics to 10+ years for others. The conclusion encourages reducing plastic pollution by recycling plastic waste. Plastic waste is used in many industries with building and construction using 23% and packaging using 35%. The document also discusses the different types of plastics that can be recycled through labeling codes and provides examples of end uses for recycled plastic, including crafts and mechanical applications.
This document describes the 7 main types of plastics:
1. PET is a clear, strong plastic used for food/drink packaging.
2. HDPE is versatile and used for containers, pipes, toys due to its strength and impact resistance.
3. PVC is used for medical/construction materials but is considered highly hazardous.
4. LDPE is used for bags and food storage as it is resistant to chemicals and moisture.
5. PP is used for food containers as it is heat resistant and safe.
6. PS is commonly used as styrofoam but has a very low recycling rate and is toxic when heated.
7. Other plastics include mixtures and polycarbon
There are 3 main ways to dispose of polymers: landfills, incineration, and recycling. Landfills use up valuable land and can pollute soil and water sources with chemicals leaching from waste. Incineration releases greenhouse gases and toxic fumes unless done at high temperatures. While it generates heat, modern methods can capture this energy. Recycling saves resources but separation of different polymers can be difficult and expensive. Overall, recycling is preferred but proper incineration that captures energy or biodegradable polymers in modern landfills are also options.
Recycling plastic involves collecting waste plastic, categorizing it by product type, inspecting and processing it through steps like chopping, crushing, washing, drying, mixing color if needed, extruding it into a new form, and cutting the reformed plastic into pieces. Recycling plastic is an important part of modern waste reduction efforts and prevents waste by converting materials into new products.

What is plastic | types of plastic | harmful effect of plastic | how to destr...KaranShaw10
Plastics are synthetic or semi-synthetic materials made from polymers that can be molded into various shapes. Their properties like being lightweight, durable and inexpensive have led to widespread use. Most modern plastics are made from fossil fuels but some are now made from renewable sources. There are various types of plastics that have different recyclability and reusability. China is the top plastic producing country. Plastics have advantages like being lightweight but also disadvantages like pollution if not recycled properly. Improper plastic disposal harms the environment and wildlife. Methods to reduce plastic harm include reducing plastic use, recycling, and plastic pyrolysis.
Plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humans.[1] Plastics that act as pollutants are categorized into micro-, meso-, or macrodebris, based on size.[2] The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans.[3] However, it is slow to degrade.[4] Plastic pollution can unfavorably affect lands, waterways and oceans. Living organisms, particularly marine animals, can also be affected through entanglement, direct ingestion of plastic waste, or through exposure to chemicals within plastics that cause interruptions in biological functions. Humans are also affected by plastic pollution, such as through the disruption of the thyroid hormone axis or hormone levels. In the UK alone, more than 5 million tonnes of plastic are consumed each year, of which an estimated mere 24% makes it into recycling systems. That leaves a remaining 3.8 million tonnes of waste, destined for landfills.[5][6] Plastic reduction efforts have occurred in some areas in attempts to reduce plastic consumption and pollution and promote plastic recycling.
This document discusses plastic pollution and plastic waste management. It notes that plastic production has increased dramatically since 1950 and now stands at over 300 million metric tons annually. The major issues discussed are health impacts, toxicity of chemicals used in plastic production, lack of biodegradability, and challenges with disposal and waste management. Solutions proposed include segregating plastic waste at the source, conventional recycling into new products, using waste plastic to produce fuel, and incorporating plastic waste into road construction materials. The document emphasizes the importance of individual responsibility and awareness in plastic waste management.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
2. INTRODUCTION
PLASTIC: A wide range of synthetic or semi synthetic organic
solid materials suitable for the manufacture of industrial
products. Plastics are polymers of high molecular weight. They
may contain other substances to improve performance and/or
reduce costs.
PROPERTIES OF PLASTIC:
3. TYPES OF
PLASTICS
THERMOPLASTICS: Plastics that do not
undergo chemical change in their composition
when heated. It can be molded again and
again.
Examples:
THERMOSET PLASTICS: Plastics that are
permanently "set" once, they're initially formed
and can't be melted.
Examples:
8. Effects of
Plastic on
Human
Health
The extraction of resources for plastics often involves
fracking or other invasive processes, and many release a
significant amount of harmful substances into the
atmosphere or pollute the surrounding environment. At
the other end of the plastic cycle, waste management
technologies such as incineration, gasification, and
pyrolysis also release toxic metals such as lead, mercury
and acid gases into the surrounding air, soils, and waters.
In its physical form, most of the plastics which are harmful
to us are almost invisible to the naked eye. Micro and
nano-plastics are being found in a significant proportion of
test sites, such as in sea salt, rainwater, and even
mountaintops - as the plastics evaporate and fall as
precipitation with the water molecules.
9. WHY
RECYCLE?
In landfill, both synthetic and naturally occurring polymers
don’t get the necessary exposure to UV and microbes to
degrade.
• Landfills not destroy plastics , it preserve the poison
forever.
• The toxic chemicals escape from the landfills and
contaminates the water sources.
• When there are too many plastic in landfills, they are
often destroyed in incineration factories.• Causes Lung
Cancer
• Contaminates Soil
• Contributes to
Green House effect
Consequently it:
10. PLASTIC
RECYCLING
Plastic recycling is the process of recovering
scrap or waste plastic and reprocessing the
material into useful products, sometimes
completely different in form from their original
state.
• Recycling is a viable alternative in getting
back some of the energy stored in the
polymers.
• As petroleum prices increase it is becoming
financially viable to recycle polymers rather
than produce them from raw materials.
11. RECYCLING
PROCESS
The simplest of plastic recycling processes involves collecting, sorting,
shredding, washing, melting, and pelletizing. The actual particular
processes vary based on plastic resin or type of plastic product.
Most plastic recycling facilities use the following two-step process:
Step One: Sorting plastics automatically or with a manual sort to make
sure all the contaminants are removed from the plastic waste stream.
Step Two: Melting down plastics directly into a new shape or shredding
into flakes then melting down before being finally processed into
granulates.
