In addition to chemical recycling, waste XPS can also be converted into recyclable materials through mechanical recycling. Mechanical recycling refers to XPS foam recycling by compacting and granulating XPS foam into recycled particles. Waste XPS foam is first collected and sorted, and contaminants ...
In 2005, Chinese companies started research and development of a chemical & mechanical recycling process to produces high-quality recycled PET (rPET) from post consumer resin (PCR) at low cost. Meanwhile, companies from other countries were developing screw chemical purification technology for the ...
Mechanical recycling is a physical process. Chemical recycling is a chemical process: you use solvents, acids and temperature to break down the molecular structure of the plastic waste. Let me rephrase this with vulgar scienctific words: you break down the polymer into monomers. Advanced recycling ...
Chemical recycling helps transform plastic waste into circular chemicals Mechanical recycling is best suited for recycling lightweight plastics like drink bottles or milk jugs; however, alternatives are needed for other plastics that cannot be mechanically recycled and are currently destined for incineration...
Cleaning apparatus, by chemical action and associated mechanical, fiber-foams and cork residues colles--organic-residue naturelles- foams attached to soil or any flat surface in the floor and wall requiring treatment. The invention consists in a hand tool, using a flexible straight blade (1) or...

Slurry recycling apparatus and slurry recycling method for chemical-mechanical polishing technique A first pump collects used slurry which is employed for a CMP technique. A new slurry supply device supplies new slurry having a concentration higher than a concentration of the used slurry, to the ...
Recycling cycles cause a decrease in mechanical paper properties due to cellulose fiber degradation. The use of cellulose micro/nanofibers (CMF/CNF) to reinforce paper strength has been well studied, although it has been found to have negative effects on drainage. However, the application of CMF/...
Chemical recycling is one of two major ways to recycle waste plastic. It splits polymer chains and creates products such as oil. The other way is mechanical recycling, which crushes waste to make new plastic products. 化学回收是回收废塑料的两种主要方法之一。它分裂聚合物链并产生诸如油之类的产品...
When it comes to recycling, not all plastics are created equal. Traditional, mechanical recycling is not suitable for high performance plastics which combine several materials to achieve a certain function (e.g. multi-layered packaging that can keep food fresh...
