Every year, untold tons of lawn clippings end up in landfills – or at best, in compost heaps. US Department of Agriculture chemist Syed H. Imam, however, has come up with what could be a better use for them. He’s been making them into fireplace logs, that have some big advantages over conventional artificial logs.  Read More

A Hong Kong company is selling 100% biodegradable fast food containers, made from waste st...

Not only are polystyrene fast food containers usually not recyclable, but they also take eons to break down in a landfill, can emit harmful compounds, and require petroleum to create. Using paper is one alternative, but Hong Kong-based company Innovasians is now offering another – 100% biodegradable containers made from waste straw left over after wheat harvesting.  Read More

Meat and bone meal (pictured above) has been used to create partially-biodegrable bioplast...

Creepy as it may sound, for decades one of the key ingredients in cattle feed was meat and bone meal (MBM), made from by-products of – you guessed it – slaughtered cattle. Sheep, farmed deer, elk and bison were also unknowingly eating their own kind. With the onset of the Mad Cow Disease scare in 1997, the U.S. and other countries banned the use of MBM-containing feeds, as it was believed that the disease could spread via the ingestion of infected animals' body parts. That ban has resulted in large quantities of MBM simply ending up in landfills. Now, however, scientists are suggesting that it could be used to make green(ish) plastics.  Read More

The INTI study has identified a sustainable process for creating water-soluble natural dye...

Researchers at the Argentine National Institute for Industrial Technology (INTI) are taking a new approach to the manufacture of natural dyes from agricultural waste. The method involves extraction of pigments from waste and conserving them in dust form, meaning they can be dry stored for use all year round. Over the past year numerous agricultural materials have been tested with one of the most promising candidates being peanut shells – one of Argentina's main exports.  Read More
