Best answer: What are the cons to mechanical recycling?

Cons: Higher water and energy demand than alternatives as a result of washing and drying requirements. Still requires an understanding of structure composition prior to beginning process. This makes it unfeasible for curbside collection programs and limits processing to one structure format at a time.

Is mechanical recycling safe?

Mechanical recycling requires plastics that can actually be recycled. … According to the European Food Safety Authority, granulate from mechanical recycling cannot be used in food packaging. The granulate could contain substances that are hazardous to health and might get into the food.

Is mechanical recycling expensive?

Mechanical recycling is very expensive, the end product (recycled plastic) is very expensive compared to virgin plastic. It’s claimed that chemical recycling will produce cheaper recycled plastic.

Why is mechanical recycling of PET difficult?

Mechanical recycling

It is difficult to recycle contaminated PET waste mechanically because of the complexity of the waste stream. The major issues for mechanical recycling are the heterogeneity of the PET waste and deterioration of the product properties each time it is recycled.

What is mechanical recycling?

Mechanical recycling refers to operations that aim to recover plastics waste via mechanical processes (i.e. grinding, washing, separating, drying, re-granulating and compounding).

What are the benefits of mechanical recycling?

Firstly, fewer new (fossil) raw materials are needed. In addition, it offers a solution for the large amounts of waste. Recycling waste streams also produces less CO2 emissions than producing new raw materials.

How does mechanical recycling work?

In mechanical recycling, plastic waste (sorted by material type) is milled and washed, passes a flotation separation, and is dried. The plastic flakes are then either used directly to produce new plastic materials or they are processed into granulates beforehand.
