Sustainability challenge of the aluminum industry: transforming wastes into p...Marcelo Suster
The work that follows is a contribution to the aluminum industry’s sustainability. It deals with the critical issue of solid wastes accruing to that sector. By-products from aluminum refining are solid wastes, liquid effluents and gaseous emissions. Each kilogram of metal produced is accompanied by three and a half kilograms of bauxite residue, commonly known as red mud. Current practice is to use decantation lagoons that are built with elaborate precautions for preventing environmental contamination. The aim of the present work is to investigate this pollutant within the perspective of current solid industrial waste technologies, and to study the practicalities for utilization and new processes. The very high ratio residue/end product provides a strong incentive insofar as the residue concerned does in fact offer numerous commercial opportunities. Thus the feasibility of converting the residue into a raw material is a real alternative to landfill disposal. Numerous industrial processes and technologies have been considered in relation to environmental legislation, industrial marketing, competitive processes and other factors. In conclusion the subject paper recommends a series of activities that would achieve transformation of red mud into valuable substances and substitute other existing raw materials without adversely affecting quality and the environment.

The role of material in fertilizers industries with energy savingPremBaboo4
In Fertilizers industries the material plays a very important role. Right material can save energy as well as plant life and wrong selection of material may lead to catastrophic failures and outage of plants & even loss of Human lives, Right selection of material leads to long life of plant. In urea plant very corrosive chemicals are used for urea production. The raw material of urea plant is Ammonia and Carbon Dioxide gas which makes very corrosive chemical ammonium Carbamate. For reduced corrosion passivation air is used in reactor as well as stripper according to material of selection different quaintly of air is used. Controlled and less quantity of passivation air is required for Titanium and Zirconium material and hence saving of energy because the huge amount of ammonia is waste with venting of inerts, i.e. saving of energy and environments also. Passivation oxygen given in CO2 is directly proportional to ammonia losses in MP section. This paper intended how to increase life of urea reactor liner and energy saving with low passivation air and high N/C ratio, Ammonia is the noncorrosive and ammonia to CO2 Ratio is an important parameter for process optimization occurring less losses and less explosion probability in urea reactor because it affects the amount of produced urea and corrosion to the material in the reactor. Generally we are using urea reactor liner 316L (urea grade), now adopted 2RE69 for large capacity plant (world largest) and Duplex stainless steel.

The document describes experiments on forced fluid imbibition in a powder-packed column. The objectives are to develop a tool to measure contact angles and surface energies for both spontaneous and non-spontaneous imbibing liquids in powders. The experiments apply vacuum to induce imbibition in cases where the wetting angle is larger than 90 degrees. Image analysis is used to measure rising rates of different liquids, including hexane, water, methanol, ethylene glycol and glycerol under varying vacuum conditions. The results show reproducibility is better for hexane than water, and rising rates increase with higher vacuum levels and lower liquid viscosity.
WoodWorks is expanding its pilot program to promote structural wood in commercial construction. The program originally focused on specific regions but will now operate nationwide. It has been successful through educating architects and engineers, providing technical assistance, and supporting projects from design through construction. Over 500 building conversions have been achieved already worth over $128 million. New focus areas include engaging with national accounts on multiple building projects, promoting mid-rise wood buildings, targeting the school market, and developing building systems using cross laminated timber and tall wood walls. "Wood champions" who advocate for wood will influence other initiatives. Tools used in outreach include carbon calculators and an online resource center.
The document discusses value addition to wood resources through the production and export of garden furniture in Ghana. It analyzes the recovery rates and costs associated with converting lumber to garden furniture for 11 wood species used. Key findings include:
1) The average recovery rate for converting lumber to garden furniture was 59.07%. Higher value species like Odum had higher recovery rates.
2) Producing garden furniture added significant value, with furniture prices averaging €2,000/m3 compared to €368/m3 for lumber.
3) Total production costs averaged €1,869/m3, leaving a 6.55% profit margin. Higher costs were found for scenarios where all costs went to furniture versus
This document summarizes a study on entrepreneurship in the forest products industry in southern Malawi. The study aimed to identify the characteristics of entrepreneurs in Malawi's distressed economic environment. It found that most forest product entrepreneurs were necessity-driven with only primary education and little business experience. Key success factors included honest business practices, negotiation skills, adequate finances, and vocational training. Entrepreneurs faced challenges such as lack of capital, desired business training, low customer incomes, deforestation, and lack of wood drying and basic power tools. Some innovated by creating lathes and utilizing new tree species. The study provides insights into entrepreneurship in sub-Saharan Africa's informal sector.

5th Power Grid Model Meet-up
It is with great pleasure that we extend to you an invitation to the 5th Power Grid Model Meet-up, scheduled for 6th June 2024. This event will adopt a hybrid format, allowing participants to join us either through an online Mircosoft Teams session or in person at TU/e located at Den Dolech 2, Eindhoven, Netherlands. The meet-up will be hosted by Eindhoven University of Technology (TU/e), a research university specializing in engineering science & technology.
Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.

7. Definitions
Carbon footprint assessment1: “Cradle to Gate”
“A measure of the greenhouse gases that are produced…that involve burning
fossil fuels.”
Life cycle assessment2: “Cradle to Grave”
Life Cycle Assessment (LCA) is an internationally standardised methodology (ISO 14040).
LCA helps to quantify the environmental pressures related to goods and services
o Life Cycle Inventory:
The collection and analysis of environmental interventions data (e.g. emissions, waste generation and resource
consumption) which are associated with a product from the extraction of raw materials through production and use to final
disposal, including recycling, reuse, and energy recovery.
o Life Cycle Impact Assessment:
The estimation of indicators of the environmental pressures in terms of i.e. global warming potential, acidification, human
toxicity, eutrophication, photochemical oxidation, freshwater & terrestrial ecotoxicity and abiotic depletion associated with
the environmental interventions attributable to the life-cycle of a product.
The data used in LCA should be consistent and quality assured and reflect actual industrial process chains.
Methodologies should reflect a best consensus based on current practice.

13. Realism and conservatism
Wood
o Assume radiata pine sourced from New Zealand
o Local species sourcing could improve carbon footprint
Acetic anhydride
o Two routes for production (ketene & carbonylation)
o Embodied energy for global production mix was used
o Increased focus on use of carbonylation route could improve carbon
foot print
Acetic acid
o Assume acid enters merchant market and displaces petrochemical
produced acid, a net carbon credit
o Internal recycling back to anhydride could have similar benefit
Site location
o Base case is for Netherlands site, not co-located with timber or
anhydride production
o Co-location with either feedstock could improve carbon emissions

29. Conclusion
o Accoya® wood has a much lower environmental impact compared to many common
alternatives including metals and concrete
o While Accoya® has a slightly higher environmental impact than sustainably sourced
hardwoods, it is significantly more efficient than woods produced under poor forestry
practices
o Additional benefits not accounted for:
o Certified tropical hardwoods are not widely available
o Mean annual increment (MAI) for fast growing softwoods is much higher than tropical
hardwoods
