Producing biodegradable plastic just got cheaper and greener

Biodegradable drinking cups or vegetable wrapping foil: the bioplastic known as polylactic acid (PLA) is already a part of our everyday lives. And yet, PLA is not yet considered a full alternative to traditional petroleum-based ...

Sustainable 'plastics' are on the horizon

A new Tel Aviv University study describes a process to make bioplastic polymers that don't require land or fresh water—resources that are scarce in much of the world. The polymer is derived from microorganisms that feed ...

Turning desalination waste into a useful resource

The rapidly growing desalination industry produces water for drinking and for agriculture in the world's arid coastal regions. But it leaves behind as a waste product a lot of highly concentrated brine, which is usually disposed ...

Low-cost process produces natural gas from algae

(PhysOrg.com) -- A new method for converting algae into renewable natural gas for use in pipelines and power generation has been transferred from the Department of Energy's Pacific Northwest National Laboratory to the marketplace ...

Using bacteria batteries to make electricity

(Phys.org) —Their idea is state of the art: Ten Bielefeld students have set their sights on constructing a bio-battery. They want to make use of the bacteria Escherichia coli to convert glucose into energy. With this project, ...

Why 'baking powder' increases efficiency of plastic solar cells

The efficiency of plastic solar cells can be doubled or tripled if an extra solvent is added during the production process, comparable with the role of baking powder in dough mixture. Exactly how this works has been unclear ...
