Recycle

Recycled vs Virgin materials

Recycled materials informs about the part of any material made from recycled materials.

Recyclability

Materials are recyclable if collected, sorted, reprocessed, and ultimately reused in manufacturing or making another item. This is about the part of a material that can be recycled.

Even though many materials can be (partly) recycled in theory, many materials do not get recycled in practice. There are many different reasons why materials do not get recycled. Mostly it is because it is too difficult to recycle or it costs too much money or energy.

Different types of recycling

Upcycling

Reuse (discarded objects or material) in such a way as to create a product of higher quality or value than the original. Upcycling basically provides things a second existence, it revives the object but with a higher user value than what it had in its previous life. Upcycled objects include everyday items such as furniture, ceramic materials, cans, clothing, and glassware

Recycling Codes

Many materials have a symbol which is called a recycling code. The recycling code is a number that indicates what material the product or part of the product is made from. The materials are sorted on how they should be recycled. Not all materials have a recycling code. For example, rubber does not have a recycling code. However, rubber can be recycled. The recycling codes makes the recycling process easier for recycling facilities. Also when a material does have a recyclingsymbol does not mean that the material can be recycled. Reycling number 1-6 are plastics that can be recycled. Number 7 is for al the other plastics and these plastics do not get recycled, they get burned.

Reycling challenges, projects and solutions

Recycling multi-layer and multi-compound packaging

Problem

Multi-layer packaging is very important and effective when it comes to the protection of goods, prologue shelf life and to optomise managing food waste. However, the structure of multi-layer packaging is very complex making it nearly impossible to recycle, leading yo a growing amount of packaging and especially plastic waste.

Project and solution

Terminus is an organisation that tries to solve the recycling problem of multi-layer packaging. 'Terminus aims at unlocking the recycling of multi-layer packaging via a range of smart enzyme containing polymers with triggered intrinsic self biodegradation properties' | Terminus

The polymers that act as an adhesive in multi-layer plastics are what make it difficult to recycle en separate the layers. The technology that Terminus uses will be applied to biodegradable PUR-based adhesives. COntrolled bio-degradation of these adhesives and tie layers would enable the separation of the different layers of the packaging, which can then be recycled using conventional recycling methods.

Increasing the recyclability of multi-layer packaging will significantly aid the efforts of reaching the European plastics and packaging recycling targets, as well as contribute towards the establishment of a circular economy for packaging.

project impact fo Terminus: 15% improvement in economic efficiency 55% reduction of plastics in landfills 65% overall CO2 footprint reduction 80% reduction of multi-layer plastic packaging in landfills
