Plastics have surpassed most man-made materials ever. It is estimated that 8300 million tonnes (Mt) from virgin products have been produced to that date. In 2015, around 6300 Mt of plastic waste was created, of which about :
If this current waste management trends continue, about 12,000 Mt of plastic waste will be in landfills or in the natural environment by 2050 an we estimate nearly 2,500 Mt of plastic waste will be recycled.
The only way to permanently eliminate plastic waste is the destructive heat treatment such as hydrolysis of combustion. So, the almost permanent contamination of the natural environment by plastic waste is a growing topical issue. Plastic debris has been found in all ocean basins, with about 4 to 12 million tonnes (Mt) of plastic waste generated on land entering in the marine environment in 2010 solely.
Contamination of freshwater systems and terrestrial habitats is also increasingly reported, as is environmental contamination by synthetic fibers. Plastic wastes are now also omnipresent in the environment.
The largest groups in total plastic production are PE (high and low density polyethylene) (36%), PP (polypropylene) (21%) and PVC (polyvinyl chloride) (12%), followed by PET (terephthalate) and PS (polystyrene) (<10% each). The highest recycling rates in 2014 were in Europe (30%) and China (25%), while in the US, plastics recycling has remained stable at 9% since 2012 and the rest of the world had recycling rates similar to those in the United States.
About 42% of all plastics were used for packaging, which is mainly composed of PE, PP and PET. The construction sector used 69% of all PVC.
In Morocco, opportunities for recycling development remain enormous and not yet sufficiently exploited. This sector is divided into four sectors. In addition to plastics and glass, the paper and cardboard sector, as well as metals, continue to generate significant capital gains through the revaluation companies operating in the sector. The country embarks on the circular economy wants to increase its overall recycling rate by 8%.
It has received support from the World Bank, aiming for a 20% recycling rate by 2022 and wants to improve the living conditions of waste collectors.
In Morocco, around 250 000 tonnes escape from recycling each year. Around 10 formal operators are active in collection and revaluation. The predominant use of plastic remains concentrated mainly in the following three sectors :
Currently recycled plastic products are reused by both formally identified and non-registered companies in the manufacture of various industrial products such as sandals, boots, pipes, greenhouse films, etc. The highlight is that most of this second-hand raw material is not reused in the industrial sectors where it has been used for the first time, namely for a large part, the food industry (bottles and cans). oil) and chemistry (bottles and bottles of bleach, for example). This is due to the fear, in the case of the agri-food industry, of the inadequacy of the health status of the recycled products. The following diagram illustrates the life cycle of plastic products.
Recycled PE and PVC products can be reused in the manufacture of chemical packaging.
VALOR-M Industrie will produce approximately 5000 tons of recycled raw material polymer pellets for plastics.
