Better Material Properties and Faster Catalyzed Chemical Recycling for Poly(L‐Lactide) Using a Simple Commercial Glycerol Ethoxylate Additive

Chemistry – A European Journal, EarlyView.
Glycerol ethoxylate (GEO), a branched ethylene glycol derivative, both toughens commercial PLLA and accelerates its chemical recycling to L‐lactide. The lead sample, containing 10 wt.% GEO, shows 9x higher elongation at break and 6x higher tensile toughness than pure PLLA. The GEO–PLLA samples are efficiently chemically recycled to L‐lactide, even when

State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production

Chemistry – A European Journal, EarlyView.
The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...

Integrated Selective Depolymerization and Downstream Processing for Mixed Polyester Waste, Part 1

Chemie Ingenieur Technik, EarlyView.
Chemical recycling of mixed plastics by hydrolysis generates dilute monomer mixtures requiring complex downstream purification. To overcome this challenge, upstream selectivity is targeted. Tailored reaction conditions enable cascaded depolymerization which is shown for a PLA/PET model system.

Microplastics and nanoplastics in water: Improving removal in wastewater treatment plants with alternative coagulants

The Canadian Journal of Chemical Engineering, EarlyView.
The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

A Social Entrepreneurship Perspective of De‐Carbonising the Footprint through Recycling Compensation: A Case Study of the NGO Madre Coraje

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This research analyses the carbon footprint of the NGO Madre Coraje, using an integrated methodology that combines the calculator provided by REAS (Red de Economía Alternativa y Solidaria) Navarra and the Life Cycle Assessment (LCA). It quantifies emissions across the three scopes of the Greenhouse Gas Protocol, evaluating both direct and ...
