Producing bioplastics from sewage bacteria is much cheaper than producing bioplastics from sugar!

Breaking news – Sewage purification company Delta has made bioplastic with bacteria from the sewage.

In a pilot project, researchers used bacteria that normally purify the wastewater in the sewer installation which you will find everywhere in the world.

We have fattened the extinct bacteria with some acidic wastewater. like a kind of ‘essential oils’ the bacteria are stringing them together into fatty acids, the material for raw bioplastic Poly Hydroxy Alkan Oaten (PHA) which is the basic for biobased raw materials like biodegradable plastic bags.

New is that bioplastics are made by bacteria that first have purified sewage from pee and poo. Until now PHA-plastic are mainly produced from sugar beets.

Cheap

Producing bioplastics from sewage bacteria is much cheaper than producing bioplastics from sugar.

At this moment, the plant is producing a few kilograms per week, but soon the Bath water treatment could produce 40 tons of plastic granules per week.

Now we know how it works. The next challenge is to convince the crowd that we can produce a beautiful high qualify product with the same bacteria which first have been used for the purification of pee and poop
