The scale and visible nature of the plastic pollution problem has captured grassroots imagination like no other environmental issue

Our origin

Polymateria was set up in 2015 to understand why efforts to address this issue had largely failed and bring together new scientific approaches to scale and address the problem.

We founded Polymateria as we wanted to create a British company with the ambition and capability to be the global leader in solving the world’s fugitive plastic epidemic.

Fugitive plastics

If current trends continue, the total amount of plastics in the natural environment will reach 4 billion tons by 2050 with packaging accounting for roughly two thirds of this (polypropylene packaging alone accounts for 130 million tons.)

32% of this leakage winds up in the ocean with 68% remaining on land. Reducing the amount of plastics that would end up in the oceans alone by 2050 would cost c 1.6 trillion USD.
