Catalytic Chemical Recycling of Post-Consumer Polyethylene.

Journal of the American Chemical Society, 2022
Among commercial plastics, polyolefins are the most widely produced worldwide but have limited recyclability. Here, we report a chemical recycling route for the conversion of post-consumer high-density polyethylene (HDPE) into telechelic macromonomers ...

Current Concepts and Future Directions of CELSS [PDF]

, 1985
Bioregenerative life support systems for use in space were studied. Concepts of such systems include the use of higher plants and/or microalgae as sources of food, potable water and oxygen, and as sinks for carbon dioxide and metabolic wastes.

Chemical recycling of polyesters

Polimery, 2019
In the presented paper, two basic strategies that can be used in the processes of chemical recycling of polyester material were described. The first of them involves increasing the molar mass of recycled materials in the solid-state polycondensation (SSP) process and/or joining their chains with various types of substances easily reacting with the end ...

Eco-Friendly Synergetic Processes of Municipal Solid Waste Polymer Utilization [PDF]

, 2018
The synergetic approach for eco-friendly efficient utilization of Polymer Solid Waste is presented. It is accounting for chemical processes in polymers during the use of the original product and at the stage of its waste recycling.

Polyurethane Foam Chemical Recycling: Fast Acidolysis with Maleic Acid and Full Recovery of Polyol

ACS Sustainable Chemistry and Engineering
Chemical recycling of polyurethane (PU) waste is essential to displace the need for virgin polyol production and enable sustainable PU production. Currently, less than 20% of PU waste is downcycled through rebinding to lower value products than the ...
