This new technology overcomes both the inherent difficulty of chemically recycling addition polymers like polyethylene (PE) and the energy intensity of thermolytic methods. From polyethylene (PE) and polypropylene to tire rubber, the principal challenge in chemically transforming addition-reaction polymers is their chemical inertness. Indeed, like its lower-molecular-weight, paraffinic homologs, PE is “parum affinis” (Lat., without affinity): it is relatively unreactive. Thermolytic methods overcome that inertness by thermally energizing all bonds in PE, both C-H and C-C, thereby “pushing” them over the activation barrier to bond-breaking.Continue reading “Hydrochemolytic Upcycling of Polyethylene: An Efficient, Lower-Energy Technology to Produce Paraffins in High Yield and Purity”
Promeco was esthabilished in 1996, in Como, Italy and we manufacture, on unique proprietary technology, plants and equipment for waste recycling, material recovery or production of finished goods.
We began with pure engineering in the 1990s and moved to construction of single machinery to be used in our plants and process and now we can develop tailored solutions to specific requirements.
We have now about 25 years of experience in technologies for waste recycling and recovery of materials.
Our business is about :
- Manufacturing of machinery and turn key plants for waste recycling:
• Mechanical recycling of plastics and many other materials
• Chemical recycling for plastics since 2008
Why are you stepping into chemical recycling
Because we were looking for innovative technology to endlessly recycle all plastic waste for a more sustainable and circular economy. We were looking for a reliable alternative to landfill and incinerators for mixed post-consumer plastic waste, which is the most increasing waste worldwide.
We developed a solution for waste plastics that currently cannot be recycled mechanically, e.g. multilayer, multi-material, coloured or film plastics
We have been developping chemical recycling since 2008 when we engineered our “plastic to fuel” plant, which is about the cathalitic conversion of waste plastics into fuel oil, coke and gas.
Our technology is based on cathalitic cracking, which is an improvement of the pyrolysis method.
We use and additive that breaks the complex hydrocarbons into simpler molecules while the temperature conditions reduce to 300-400 degrees and lower pressures of 10-20 psi.
Quantity of yield also increases to almost 80%
What are you offering in chemical recycling
The Promeco patented plastic to fuel plant, that is an high efficiency and continuos process in recycling plastic waste.
The Feedstock is made of post-consumer mixed waste plastics.
The plant is capable of recycling approximately 30 metric tons of plastic waste per day.
Which is about 1,5 ton per hour.
Feedstock features: polymer 80%
Not polymer 10%
Yield: 1 kg of polymer = 1litre of hydrocarbon fuel = 5000 kW/H OF ENERGY
The products from out plastic to fuel plant are:
Fuel Oil – that can be directly used as furnace oil and blending for use in generators, pumps, boilers, and marine bunker fuel or can be added to the plastic manufacturing blend
LPG – To generate electricity using power generators
Coke – to be used as solid fuel for burning
The Quality of the output is dependent on the quality of the materials processed. This material should be pre-processed and cleaned, and for this purpose, Promeco can offer the pre-processing plant too.
- The feedstock we use is available in every country
- The process has a low environmental impact
- There are no CO2 (Carbon dioxide) emissions
The products is high efficient and with high profitability
It is a sustainable alternative to fossil derived fuel and replaces crude oil
Such waste plastic-derived fuel can be delivered to a third party plastic manufacturing company to be added to the blend for plastic production in order to have a greener product.
It is used to partly replace crude oil as refinery raw material. The refinery processes can turn the “liquefied” waste plastic into raw material for new plastics and chemicals.
The plastics and chemicals based on chemical recycling are of high quality and can replace products based on virgin fossil resources in any application.
Plastics based on chemical recycling can be used without limitations in several applications.
Promeco is partner of the 2020 edition conference.

The presentation is focused on microwave assisted chemical recycling process able to up-cycle the PET/polyester. The chemical recycling is not presented as one of the recycling methods but as a complementary technology to the mechanical recycling. The beneficial effect of this synergy is the potential terrific increase of the recycling rate because the chemical recycling is able to deal with contaminated and complicated packaging and garments.Continue reading “Circularity PET/Polyester evolution or revolution?”

There is a a widespread belief that Chemical Recycling processes allow to recycle the mechanically unrecyclable mixed polymer packaging. However thermo-chemical processes like Pyrolysis also need quality feedstock to produce quality oil !
The presentation will explain why it is essential for the circularity of plastics to continue the industry efforts in redesigning multi-polymers into mono-polymer packaging.Continue reading “Designing plastics packaging for chemical recycling”

Europe is at a crossroads for the way it manages plastic, plastic waste, and plastic waste trade. Plastic and plastic waste is traded worldwide. Exports from the EU to Asia have been a means to deal with insufficient recycling capacities in the EU. Waste import restrictions in China and Hong Kong have triggered a shift of exports to other countries.
Since some types of plastic waste have been added to the UN Basel Convention, the option of exporting plastic waste is becoming increasingly difficult, requiring to build a more robust and circular economy for plastic in Europe.Continue reading “Operationalisation of new plastic value chains for a circular economy”

The recycling of many plastic waste streams like mixed plastics, composites or plastics with inorganic and organic contaminations remains very challenging. As an addition to mechanical recycling, chemical recycling offers the chance for closing the plastic recycling loop. Currently, great amounts of plastics are still incinerated and removed from this loop.Continue reading “Chemical Recycling of Plastic Waste – Pyrolysis and downstream processing of pyrolysis oils”
