Environmental Analysis of Hydrothermal Decomposition of Melamine Etherified Resin Fibre

Plastic waste presents a significant problem for the environment as significant amounts of plastics are produced, of which the majority are still landfilled contaminating soils, waterways and aquifers. A particular challenge present thermoset plastic material, which are more difficult to recycle com...
