#24 A Journey Through Sustainability, with Insects, Plus... – Ft. Volker Heinz.
In this episode, you will hear from a very special guest: Volker Heinz, the director of the German Institute of Food Technologies.We discussed circularity in the food system, CO2 and nitrogen cycles, new fields, trials and errors, and alternative proteins.Dr. Heinz's journey into the world of insect-based protein began 15 years ago during a visit to the pet food industry. He recalled that during a discussion about protein sources, his interlocutor mentioned the inevitability of insect consumption in Europe. "At first, I thought he was crazy," Dr. Heinz admitted. However, during his three-hour drive back to the institute, he began contemplating the role of circularity in food systems.As an engineer, Dr. Heinz decided to establish an insect farm, driven by the belief that nothing was impossible. During this phase, he invited a leading FAO expert on insect farming, who shared insights and examples from his global research. But the expert was skeptical. "Young boy," he said, "what you are planning is like flying to the moon. Many have tried and failed." Despite this warning, Dr. Heinz remained determined. He saw an opportunity to revolutionize the industry by developing a continuous system.At the DIL (Deutsches Institut für Lebensmitteltechnik), Dr. Heinz and his team experimented extensively, creating an environment optimized for insect reproduction, including controlled light, wind, temperature, and humidity. It took several setbacks and considerations of abandoning the project before they finally succeeded."I still expect problems to come because it is indeed like a flight to the moon—but they made it, and we hope to succeed as well."Discussing sustainability, Dr. Heinz highlighted the significance of nitrogen and carbon cycles in global food production. "We rarely read about the nitrogen cycle, but it is of similar importance to the carbon cycle, particularly with 8 billion people on the planet." He explained that while nitrogen is essential for protein formation, only 20% of it is effectively recycled back into the atmosphere, with the remainder causing environmental harm. "One way to make better use of activated nitrogen is through animals," he noted. Historically, livestock played a role in nitrogen storage, but insects offer a far more efficient alternative. "Since insects are so much more efficient than livestock, there are completely new potentials that are badly needed on the planet."Looking ahead, Dr. Heinz spoke about the upcoming InsectPlus event hosted by DIL in May. "We will invite people to take part in the journey of how biomass can be used efficiently." He emphasized that the entire food system revolves around biomass conversion and that various methods—plants, animals, algae, and even precision fermentation—must be considered. "It’s all about focusing on the most efficient conversions, ensuring sufficient resources for feeding the world, and minimizing waste. Because anything we don’t circulate, we call footprint.My name is Umberto Diecinove, I am a documentary photographer and I am currently leading a project titled I N S C T S which explores the potential role of insects in addressing environmental and social challenges. I’m doing it traveling, photographing research centres, farms, communities and companies all over the world and engaging with world experts and people working in the field. I do believe insects could be the next game changer. Hosted on Acast. See acast.com/privacy for more information.
