Greener routes for recycling of polyethylene terephthalate

Egyptian Journal of Petroleum, 2016
The article reviews the different routes for recycling of polyethylene terephthalate. Chemical recycling processes are divided into six groups: methanolysis, glycolysis, hydrolysis, ammonolysis, aminolysis, and other methods.

Opportunities for plasma separation techniques in rare earth elements recycling

, 2017
Rare earth elements recycling has been proposed to alleviate supply risks and market volatility. In this context, the potential of a new recycling pathway, namely plasma mass separation, is uncovered through the example of nedodymium - iron - boron ...

Gate to gate life cycle assessment of greenhouse gas emissions and acidification potential in plastic recycling technologies in Nepal

Results in Engineering
Almost all waste management steps produce greenhouse gas (GHG) and other emissions, therefore it is vital to choose the processes with less impacts. In this study, a gate-to-gate life cycle assessment (LCA) method has been applied to compare the climate ...

Chemically recyclable polyvinyl chloride-like plastics

Nature Communications
Polyvinyl chloride (PVC) is the world's third-most widely manufactured thermoplastic, but has the lowest recycling rate. The development of PVC-like plastics that can be depolymerized back to monomer contributes to a circular plastic economy, but has not been accessed.

Three Stage Bleaching of Recycled Fibers Containing 30% Groundwood [PDF]

, 1978
A three stage bleaching sequence for a mixture of recycled chemical and groundwood fibers was investigated for maximum brightness increase. The three stages consisted of a reducing or color stripping stage, an oxidizing stage, and last a mild alkaline ...

Stochastic theory of protein synthesis and polysome: ribosome profile on a single mRNA transcript

, 2011
The process of polymerizing a protein by a ribosome, using a messenger RNA (mRNA) as the corresponding template, is called {\it translation}. Ribosome may be regarded as a molecular motor for which the mRNA template serves also as the track.
