Can Black Soldier Flies turn food waste into fuel?

KAKALI DAS

In the UAE’s desert, where innovation thrives out of necessity, Circa Biotech is revolutionizing waste management by harnessing the power of the Black Soldier Fly to convert discarded food into biofuel and alternative protein.

With bold plans to expand, this pioneering startup is demonstrating that sustainability goes beyond waste reduction—it’s about reimagining how we use resources.

Could insects be the overlooked champions of the Green Energy Revolution?

Can Black Soldier Flies turn food waste into fuel?

Amidst the towering skyscrapers and endless sands of the UAE’s desert, a ground-breaking solution to one of the world’s greatest environmental challenges is emerging.

Circa Biotech, an innovative company based in Abu Dhabi’s Al Ain region, is addressing food waste by transforming it into valuable resources—biofuel and alternative protein. The secret behind this groundbreaking innovation? Insects.

Founded by the visionary duo Kristine Wong and Dr.HaythemRiahi, Circa Biotech leverages the remarkable efficiency of the Black Soldier Fly (BSF) to convert food waste into sustainable, high-quality products.

The Black Soldier Fly has an insatiable appetite for food waste. In a meticulously controlled environment, thousands of these flies are bred and put to work, rapidly consuming discarded food at an astonishing pace.

As this fly consumes enormous quantity of waste, thus in 10 days, they grow 500 times their initial weight. They eat all the food waste that are given to them. After that they are harvested and protein and oil are extracted.

The process not only redirects food waste from landfills but also greatly reduces methane emissions, a key driver of climate change. Currently managing 15 tons of food waste daily, Circa Biotech has bold plans to expand its operations to 200 tons per day within the next three years.

This expansion will allow the company to produce 22,000 tons of animal feed while eliminating 3,500 tons of methane emissions and generating 12,100 tons of sustainable aviation fuel annually.

Unlike common houseflies, Black Soldier Flies neither sting, bite, nor spread disease. In fact, adult Black Soldier Flies don’t even eat—they exist solely to reproduce, laying eggs that hatch into larvae, the true powerhouses of the process.

“The black soldier fly don’t have a mouth. So they don’t eat, they don’t stink, they don’t bite. They only drink water. And this stage last between 10 to 14 days. For us, the purpose of this phase is to recover eggs, and this is what we will help us to continue with the cycle on and on. And we don’t need to bring other eggs from outside the facility. So this is what we call ‘the breathing phase” – Haythem Riahi, Co-founder, Circa Biotech

Once the larvae mature, they are harvested, dried, and processed. The extracted oil is converted into sustainable aviation fuel, while the protein is repurposed into highly nutritious feed for livestock and aquaculture.

In a conversation with The FutureList, co-founder Kristine Wong discussed the nutritional benefits of this protein source and its potential impact on the agriculture and aquaculture industries.

According to Kristine Wong, the Black Soldier Fly’s protein is rich in essential amino acids, vitamins, minerals, and healthy fats. These larvae offer a powerful protein source comparable to traditional options like fish meal, with the added advantage of beneficial fatty acids. This nutritional profile can greatly enhance animal growth and overall well-being.

In agriculture, incorporating Black Soldier Fly into livestock and poultry feed can enhance feed efficiency and animal health, potentially reducing dependence on traditional feed sources. In aquaculture, these larvae could revolutionize fish feed, alleviating pressure on overexploited wild fish stocks and promoting more sustainable practices.

Circa Biotech’s ground-breaking efforts align with the UAE’s broader vision of sustainability and economic diversification. By partnering with industry leaders, the company is positioning itself at the forefront of the Green Energy Revolution, demonstrating that innovation and environmental responsibility can go hand in hand.

Food waste isn’t just a problem in the UAE—it’s a global crisis. In fact, one-third of all food produced worldwide is wasted, with the majority ending up in landfills.

Their solution not only tackles this challenge but also creates a circular economy that benefits industries globally. With its rapid growth and dedication to sustainability, Circa Biotech is setting a benchmark for nations aiming to address food waste while developing alternative energy sources.

Insects may be small, but when harnessed properly, their impact could be nothing less than revolutionary.
