2021-06-11 · 100 Mt of PP

Polypropylene (PP) is a thermoplastic from the polyolefins group. The methyl group improves mechanical properties and thermal resistance, although the chemical resistance decreases. It was discovered in 1951. Keep reading >

The main ways of processing plastic waste include recycling it back into plastic, producing new materials, producing plastic-derived liquid fuels, and using it as refuse derived fuel (RDF). Keep reading >

2021-06-03 · Recycling plastic into plastic

The plastic production process starts with base molecules which are turned into monomers, which are turned into polymers, which are turned into plastic pellets that are used to make plastic products. To recycle plastic waste into new plastic products, the material has to be broken down into one of these previous stages of the production process. The term physical recycling refers to plastic recycling methods where the polymers remain intact; chemical recycling refers to methods where the polymers are broken down. Keep reading >

2020-10-05 · Incineration

Incineration is a technical term for controlled combustion. Often referred to as burning, combustion is a high-temperature exothermic chemical reaction between a fuel and an oxidant, in this case waste and atmospheric oxygen. Heat and light energy is released during this reaction and transferred to the surroundings, hence it is called an exothermic reaction. Incineration is a thermal treatment method suitable for different types of waste. Municipal solid waste (MSW) and other non-hazardous waste can be readily incinerated. Keep reading >

2020-10-04 · Thermal treatment of waste

Thermal treatment methods significantly reduce the volume of the waste and destroy all pathogens present in it. These methods allow to recover the calorific value of the waste in a form of energy, hence they are often referred to as waste-to-energy or energy-from-waste. Incineration, waste combustion in the presence of oxygen, is the only method currently widely used on an industrial scale. Keep reading >
