BlueToff, thanks for the question.
Plastic recycling in the Uk is dealt with using plastic Recycling Centres which positively sort for certain products.
Typically:-
PET Bottles - these are washed and recycled into rPET
HDPE Milk Bottles - There are refused as a percentage into new milk bottles as rHDPE
Certain PP from bottles and packaging - for rPP
Then you have pipe recycling for example PE and PVC and then a full dedicated recycling of PVC window and pipes which is used in new windows and pipes.
Industry is well set up in the UK and across Europe for these processes although the investment was limited as the energy consumption and water usage in these processes is expensive. Typical costs of 'rPolymers' are more expensive than new or 'virgin' polymers due to shipping energy and processing costs. The use is driven by the green agenda, but to be honest it is vital that we use these plastics again. The Oil industry don't like it though as they are already on a huge decline.
The key parts of these plants are sorting equipment using IR and camera tech, density separation, metal separation to remove non desirables, then washing plant to remove food and chemical contaminants. Then next step is size reduction, shredding and granulation to bring the parts to a size of 8 to 10mm which can then be feed into the system - either for reprocessing into 'rPolymer' or feeding into the DMG process to produce power and or hydrogen. These projects will be managed by either PHE or other partners or potentially large recycling companies like Biffa, Viridor, Veolia, Grundon who could be potential customers around Europe of the these plants. Of course Protos is the first partner. We could see a consortium of energy suppliers getting involved like the oil companies, think BP and Shell as well as new hydrogen companies.
There are many opportunities for recycled plastics, but contamination and quality are the key stumbling blocks. This process reduces the cost and the risk and turns the waste polymers directly into a highly valuable product be it electricity or hydrogen.
Not sure if this answers your question but gives you some insight. Here is a plastic washing plant! https://youtu.be/4T8xZwyLVNs?t=1
