As global populations escalate and the demand for food and feed intensifies, the generation of agri-food waste is becoming an increasingly critical issue. Addressing this challenge is crucial for optimizing food production and advancing sustainable waste management practices. In this context, insects, including the Black Soldier Fly (BSF, Hermetia illucens), present opportunities for circularity through the bioconversion of organic waste.

Solid-liquid biphasic absorbents are a promising solution for overcoming the high-energy consumption challenge faced by liquid amine-based CO capture technologies. However, their practical applications are often hindered by difficulties in separating viscous solid-phase products. This study introduces a novel nonaqueous absorbent system (PD/PZ/NMP) composed of 4-amino-1-methylpiperidine (PD), piperazine (PZ), and -methyl-2-pyrrolidone (NMP), engineered to produce easily separable powdery products.

Dealing with radioactive waste, particularly from various industrial processes, poses significant challenges. This paper explores the use of lithium aluminate borate (Li-Al-B) glass matrix as an alternative method for immobilizing radioactive waste, focusing specifically on waste generated in tin smelting industries, known as tin slag. The study primarily concentrates on transforming tin slag, a byproduct abundant in Natural Occurring Radioactive Material (NORM), into a stable and safe form for disposal.

Sustainability and environmental protection are reshaping industries, including construction, where sustainability plays a crucial role in its influence on global resource consumption and waste management. The current study has developed a reusable cement material by photo-chemical surface modification of marble powder, achieved by reacting glycidyl methacrylate with carbonate functionality. This innovative modified marble powder boosts the reusability of construction materials, unlocking new possibilities for sustainable building practices.

Background: Biowaste accounts for about 40% of total waste. Food-industry waste is one major biowaste stream. The available technological approaches to biowaste treatment are expensive, not circular, unsustainable, and they require pre-treatments such as dehydration, extraction of inhibitors, pH correction, or the addition of other organic matrices.
