📄 “Environmental Perspectives on Distributed Generation: Economic Feasibility and Risk-Based Assessment of Poultry Waste Biogas Power Plants”
👤 Mendes, A. M.

This study evaluates the economic feasibility and risk of poultry waste biogas power plants under Brazil’s Micro and Mini Distributed Generation framework. Results show positive financial indicators and low risk of infeasibility, highlighting the potential of this renewable energy approach to reduce waste, mitigate greenhouse gas emissions, and provide socio-economic and environmental benefits.

📄 “Enhanced Recoverability and Recycling of Resistant Waste Crosslinked Polyethylene via FeTiO₃ Catalyst-Assisted Slow Pyrolysis”
👤 Straka, P. et al.

This study demonstrates a promising, technologically feasible method for recycling crosslinked polyethylene (XLPE)—a material notoriously difficult to process. Using FeTiO₃ (ilmenite)–assisted slow pyrolysis, the authors achieved high liquid hydrocarbon yields (up to 92 wt.% with only 1% catalyst). The catalyst significantly accelerates XLPE degradation at structural defect sites, enabling efficient conversion of waste into valuable hydrocarbons and energy gas. The work highlights a cost-effective pathway for recovering resources from resistant polymer waste.

📄 “Separation of Silver and Cellulosic Fibers for Recycling and Reuse of Printed Electronic Devices Components”
👤 Khiari, R. et al.

This study evaluates how conventional papermaking recycling processes can be adapted to recover valuable materials from paper-based printed electronics. Using a simple paper RFID antenna containing silver ink, the researchers demonstrate that standard operations—pulping, screening, cleaning, and flotation—can achieve >70% silver recovery and >80% fiber recovery. The results show strong potential for integrating printed electronics waste into existing recycling streams, enabling both fiber reuse and silver valorization.

📄 “Effects of Contamination on the Recyclability of NdFeB Permanent Magnets via Short-Loop Processing: Review of Common Contaminants and Study on Ni Coating Residues”
👤 Laura Grau et al.

This study reviews the impact of common contaminants (O, C, Ni, Cu, Zn) on the magnetic properties and microstructure of recycled NdFeB magnets. Experimental results show that Ni contamination partially substitutes Fe in the φ-phase, reducing coercivity and remanence, with an acceptable limit of ~0.25 wt.%. Findings highlight that Ni contamination is irreversible in short-loop recycling and may accumulate over multiple recycling cycles.

🔗 https://brnw.ch/21wY6E9

Short-loop recycling of NdFeB trades a reduced ecological burden for a higher sensitivity towards contamination, as the powder is usually further processed as-is. In this investigation, the known effects of common contaminants (O, C, Ni, Cu, and Zn) introduced due to product design choices, namely f...

📄 “Design of an Energy-Efficient Pilot-Scale Pyrolysis Reactor Using Low-Cost Insulating Materials”
👤 Torres Tovar, J.A. et al.

This study presents a pilot-scale reactor for catalytic pyrolysis of low-density polyethylene, designed with a stainless-steel core and low-cost insulating materials (ceramic, refractory cement, clay bricks). The design achieves high thermal efficiency, reaching 350 °C with minimal energy input, while keeping the exterior near 32 °C, making it replicable and energy-efficient for rural and decentralized applications.

📄 “Effect of Pretreatment on the Structure and Enzymatic Hydrolysis of Pineapple Waste Biomass in Hydrothermal Deconstruction”
👤 Méndez-Durazno, C. et al.

This study shows that liquid hot water (LHW) pretreatment of pineapple-mother-plant biomass causes structural changes — depolymerizing lignin and hemicellulose at moderate severity — which dramatically improves enzymatic hydrolysis: up to ~95% cellulose conversion (vs. ~44% in untreated) and a 2.16-fold increase in hydrolysis rate.
