Complete the Circular Economy Cycle of Waste with the 4th R


Cut back on the amount of trash we generate so there is less raw material input to treat


If you reuse something as opposed to throwing it away you keep waste out of landfills


Change discarded materials into new products in order to avoid using more virgin resources

(Molecular Recycling)

We recover energy and materials classified as unusable from waste that has been rejected. We are Blue4, the 4th R of the equation

By using our Recovery technology based on Molecular Recycling we can recover 92% of the rejected waste using 4 steps.

Preparation of the rejected fraction

Waste treatment

BLUE4’s Molecular recycling

Gas treatment and energy recovery

Up to 92%* materials recovery

Retrieval of energy and by products. The 8% left is inert waste.

Section 1. Separation, Preparation and Shredding

Received waste is first mechanically sorted in a customized process in order to reach the maximum recycling levels of materials such as iron, aluminium, glass, plastics, paper, carton, etc. Then, the rejected fraction of this process becomes the new input for the next section, our Molecular Recycling technology

Section 2. BLUE4’s Molecular recycling (TTQ)

Using our patented technology and process, we reduce up to 92%* of the volume and recover the rejected waste in the form of hydrocarbon by-products – the largest fraction of which is permanent gas with energy value. Our system has been tested for a range of organic materials, from biomasses (grinded wood, sawdust, etc.) to plastics (including mixtures of different types of plastics), with extended experience in reject fractions from MSW recycling plants.
(* the percentage of waste recovered can reach 100%, which we have achieved in several industrial waste treatment cases)

Section 3. By-products and Gas treatment for energy recovery

Once by-products and gas are separated, both go through a “cleaning” process that optimizes the energy recovery based on the outputs required by the client. The by-products and gas obtained may have several applications. The process has been optimized and it is extremely efficient in terms of heat demand. Our initial aim is to use the obtained energy based on a circular economy model.

Section 4. Generation of electricity and production of hydrocarbon by-products

The system is completely adaptable to the type of waste that needs to be treated – waste that otherwise would go to landfills or be incinerated. This flexibility provides the client with several opportunities to maximize the energy recovery and by-product retrieval from the process. Electricity production will be based on micro-turbines or generators depending on the amount of waste and the needs of the client.
