Summary: This study investigated enzymatic pre-treatment of grease trap waste for biodiesel production, reducing FFA levels through an esterification reaction. Results showed that using commercial enzymes in continuous-flow experiments achieved better FFA reduction than batch processes. The continuous-flow reactors were also more time-efficient, completing experiments in less than 1.5 days compared to 6 days for batch processes.

Summary: Resource recovery through waste recycling promotes a business model with minimal waste residue and supports the circular economy by reducing energy and resource consumption and pollutant emissions. However, the sustainability of this approach depends on the valorization potential of the waste and the lower environmental impact of recycling compared to other end-of-life scenarios. Evaluations need to be done on a case-by-case basis due to the diversity and complexity of waste streams.

Summary: The aim of this study is to extract oil and produce biodiesel from different scenarios, including karanja, algae, and hybrid oil, and then conduct a life cycle assessment of the derived biodiesel. Biodiesel derived from hybrid oil showed better oxidation stability, lower density, and viscosity compared to algae and karanja biodiesel. Comparative life cycle assessment studies using GREET software showed that the total CO2 emissions from biodiesel production were 2.03 kg for S1, 1.60 kg for S2, and 1.85 kg for S3. Furthermore, the environmental impact factor was calculated for each scenario, with scenario 1 having the highest EIF of 0.235, followed by scenario 3 (0.1363) and scenario 2 (0.0989). The overall evaluation indicated that algae or hybrid biodiesel production is preferable for reducing emissions and improving biodiesel quality. Further studies on life cycle costs and sensitivity analysis should be conducted to assess economic viability and promote sustainable biodiesel production.

Summary: Traditional concrete production contributes significantly to global warming, but industrially produced geopolymer concrete can be a viable alternative to mitigate these negative impacts. This study developed new geopolymer concrete mix designs using industrial side streams and conducted a life cycle assessment (LCA) to evaluate their environmental impacts compared to traditional concrete. The results showed that geopolymer concrete with lower amounts of sodium silicate and metakaolin exhibited better environmental performance. Increasing the concentration of recycled waste in concrete mixes can further improve the environmental performance of geopolymer concrete produced from industrial side streams.

Summary: Manufacturing lightweight aggregate (LWA) through sintering technique requires balancing molten liquid phase, appropriate viscosity, and gas emission. This study found that a minimum of 50% mass fraction of liquid phase is needed to trap emitted gases during sintering, with high-calcium waste coal bottom ash resulting in larger pores compared to low-calcium ash due to lower viscosity liquid phases and higher gas emission. Hematite reduction and anhydrite decomposition were identified as contributors to gas generation during sintering.

Summary: Emerging lead halide perovskite (LHP) photovoltaics have great potential for commercialization due to their high efficiency and low manufacturing costs. However, the toxicity of lead (Pb) poses a major challenge. In this study, a model was used to simulate the fate and transport of Pb leachate in groundwater, soil, and air following hypothetical catastrophic breakage of LHP PV modules. The results showed that most of the Pb is sequestered in soil, and the concentrations of Pb in groundwater and air were below the EPA maximum permissible limits. Although the highest observed concentrations of perovskite-derived Pb in soil did not exceed EPA limits, further research is needed to assess the potential bioavailability and public health risks of perovskite-derived Pb.

Summary: This study compared the life cycle impacts of industrial-scale production of A-site cation precursor chemicals for perovskite solar cells, finding that the impacts of these precursors are similar to each other and much smaller than that of solar glass. Therefore, commercialization decisions should prioritize efficiency and stability rather than environmental concerns.
