GREEK YOGURT WASTE COULD BE USED IN JET FUEL AND LIVESTOCK FEED

Your Greek yogurt creates food waste that could one day be used in jet fuel.

That’s right—when Greek yogurt is made, it leaves behind liquid whey, which is the watery remains after protein is strained from milk. A process that mixes this waste with thousands of species of bacteria and some heat transforms the whey into a new material called bio-oil, which could be used in biofuels or additives in livestock feed.

Waste streams can be renewable feedstocks to produce biofuels and chemicals. Acid whey is an example waste stream and is produced by the Greek-yogurt industry in large volumes. This whey and other waste streams have been successfully converted into methane gas by anaerobic digesters with open cultures of microbial consortia (microbiomes). However, the revenue from methane has been relatively low. Until now, no other products could be produced with microbiomes from this waste stream. This has now changed. Here, we showed that acid whey was converted into valuable medium-chain carboxylic acids (MCCAs), such as n-caproic acid (n-hexanoic acid) and n-caprylic acid (n-octanoic acid), without addition of external electron acceptors.

The Power of Regenerative Systems

“We are called to be architects of the future, not its victims.”

Buckminster Fuller

 

In these times of increasing uncertainty and volatility we must remain adaptive and responsive to the world’s most significant challenges in order to achieve global prosperity.

One solution is a circular economic system that restructures finance and business to prioritize sustainability and accessibility across our global resource supply chain, thereby guaranteeing livelihoods around the world. This regenerative system will be formed by a new era of social and cultural awareness, one that truly appreciates the interconnectedness of mankind’s socioeconomic systems and our surrounding environment. The main challenge will be to ensure that the global system aligns with the fundamental and universal principles of life.

South Australia turns on Tesla’s 100MW battery: ‘History in the making’

The world’s largest lithium-ion battery has officially been turned on in South Australia promising to usher in a revolution in how electricity is produced and stored.

Tesla boss Elon Musk has made good on his promise to build the 100-megawatt facility on deadline or provide it free after blackouts last year that critics of the state’s Labor government blamed on pro-renewable policies.
