Merits and demerits of mechanical recycling

Mechanical recycling is potentially more effective than other recycling methods because it can save not only the energy of feedstock but also the energy for plastic production processes.

Mechanical vs feedstock recycling

Mar 26, 2021The distinction between mechanical recycling and feedstock (or chemical) recycling is that mechanical requires physical separation, whereas feedstock recycling converts mixed PE/PP/PS/PVC into basic hydrocarbon building blocks. Thus, mechanical recycling is appropriate for the primary and secondary recycling routes discussed above, through the grinding of plastic products

Nov 18, 20201) Collection rates: The feedstock for recycling is plastic waste and this needs to be collected to be fed into managed disposal routes. 40% of plastic waste is currently mismanaged and lost to the system. This rate needs to increase to provide feedstock for chemical recycling facilities, particularly in middle-income countries.

Chemical Recycling of Plastics

Mar 24, 2020Mar 24, 2020Feedstock recycling has several advantages which in principle makes this process a real alternative to the established mechanical plastic recycling processes. As it uses mixed waste that can otherwise only be incinerated, it saves raw materials [1,2,4].

Mechanical recycling of plastics is a process that involves recycling into raw materials without significantly changing its chemical structure. In Europe, mechanical recycling currently makes up 99 percent of all recycling processes. Plastics that cannot be mechanically recycled may be a valuable resource for feedstock/chemical

Recycling and energy recovery

Feedstock recycling is a complementary technology, that can help diverting from landfill certain plastic waste which cannot be sustainably recycled by mechanical processes. Examples of suitable streams for feedstock recycling include laminated and composite plastics, low quality mixed plastics streams and contaminated plastics.

INSIGHT: Chemical recycling must not hinder mechanical

Jan 29, 2021THE FEEDSTOCK QUESTION Overall, chemical recycling is seen by many as the only way to reach scale for food-packaging recycling, at least in Europe. It also gets around the challenges of the EFSA approval needed for mechanical recycling because it effectively turns plastic waste back into -like monomers.
