Spotted: Scientists from four EU countries have developed a method to turn agri-waste into car parts. The process could help reduce waste and make automobile production more environmentally sustainable. 

The scientists, who are working under the EU-funded Barbara project, have created sustainable bioplastics from food waste. For instance, oils derived from lemons have antibacterial properties and could be used to make germ-killing door handles.  

The process involves using waste from a variety of sources. The scientists first use waste from the corn industry to create chemically-engineered starch. The food waste additives, like lemon oil or crushed almond shells, are then added to create the bioplastic. This can be used as the ink to 3D-print eco-friendly alternatives to traditional automobile parts and building materials. 

Some tests have already been successfully completed, and Fiat has signed on to validate the finished products. The Barbara project started in 2017 and is scheduled to end in April 2020.
