A faster, more efficient way of recycling plant-based “bioplastics” has been developed by a team of scientists at the Universities of Birmingham and Bath. The team has shown how their chemical recycling method not only speeds up the process, it can also be converted into a new product — a biodegradable solvent — that can be…
Jackie Anderson offers a review regarding one of the most critical 3D printing topics today: materials. As innovation continues to grow, so do the options regarding software, hardware, and different types of plastics (along with many other alternatives today). In ‘Engineering Biodegradable PHA Blends,’ Anderson explores issues with plastic waste, and the need to use more…
The recent development of new polymerization methods that allow the economical production of poly lactic acid (PLA) with a higher molecular weight have effectively removed many of the limiting factors on its use, opening-up a greatly expanded application base for the plant-based bioplastic. This is happening just at a time when pressures on extended supply lines…
Although corals may look like plants, they are actually animal structures that host dense populations of algae on their surfaces. Corals provide a host for tiny photosynthetic algae. This intricate symbiotic relationship between coral and algae is responsible for maintaining the high diversity of coral reef ecosystems. Whilst coral reefs cover only one per cent of…
In nature, biological materials and organisms are part of a circular process of production and degradation. This process sustains the Earth and living things on it. Humans, however, have introduced new materials and products which do not fit into the circular economy, resulting in waste, which, as we all know, is detrimental to the health of…
Unlocking the value of a circular economy using 3D printing is leading innovation everywhere. Recovery initiatives to increase sustainability, like reusing plastic waste and turning it into 3D printing filament, are becoming more common. In tune with the need to care for Earth’s limited resources, Italian studio Carlo Ratti Associati (CRA), in partnership with global energy…
In Tokyo, a householder consults her 60-page "Garbage Separation and Disposal" system to check whether it's a recycle day for plastic bottles or for all other plastic packaging. In a coastal village in Kenya, an order has been received for 2,000 bricks made from waste plastic and earth. Read more
Extracts of lemon and almond peels can be used for sustainably produced car parts and building components. This BARBARA project jointly funded by the European Union and industry ensures that food waste can be put to good use, replacing petroleum-based plastics with more environmentally friendly bioplastics. The BARBARA project is supported by the European consortium called…
