Recycling Processes: Mechanical, Chemical and Thermal

Recycling of multi-material packaging can be divided into three main methods: mechanical, chemical and thermal. Each has its own unique features and applications that support effective waste management.

Mechanical recycling: Consists of sorting, shredding, washing and extruding plastics. It is the most traditional form of recycling, allowing materials to be reused in the manufacture of new products. Although the process is energy intensive, it has the advantage of being able to process materials directly without chemical modification.
Chemical recycling: Uses solvents or high temperatures to process plastics. This method allows materials to be broken down into their basic chemical components, which can be used to produce new materials. It is a more advanced technology, capable of processing materials that are not mechanically recyclable.
Thermal recycling: This involves burning plastics to produce electricity and heat. Although this method does not lead to the recovery of materials in the traditional sense, it allows waste to be used effectively as an energy source. It is particularly useful for materials that cannot be recycled by other methods.

Each of these methods has its place in the waste management system, and their effective use can make a significant contribution to sustainability. What innovations in recycling could emerge in the future to make these processes even more efficient?
