The global food system contributes to around 30% of greenhouse gas emissions in the world, with a major portion coming from animal-based products like meat and dairy. While protein is a crucial nutrient for human health, it is also essential to consider the environmental impact of its production. Mycoprotein, a fungal-based protein, can provide a sustainable alternative to traditional meat and dairy protein sources. According to Quorn at the Mycoprotein Summit in Kew, UK, last week, mycoprotein is an eco-friendly option that can reduce the carbon footprint of food production significantly.
Quorn, in its pursuit to have a net-positive impact on the environment, tracks every stage of its production process to evaluate its sustainability. The production of mycoprotein is much more sustainable than traditional animal agriculture as it requires significantly less land usage. While industrialized farms take up vast areas, Marlow Foods, the parent company of Quorn, relies on only two 150,000-litre fermentation towers for mycoprotein production. This eco-friendly approach results in 98% less carbon emissions than beef production.
Fungi-based protein offers an opportunity to upscale food waste into new products, which is key to a circular economy. Waste is a human concept, and the biosphere never created waste, stated Dr. Vincent Walsh, an expert in regenerative agriculture. Therefore, we should start emulating the biological principles of nature to upcycle everything. For instance, Walsh upscales fungal protein using waste products from other food companies on his farm. Fungi-based compost systems upcycle this waste material, resulting in biological materials that he can use on his farm. Thus, the collaboration with food companies is crucial for sustainable agriculture.
Joanna Trewern, head of consumption at WWF UK, emphasized the need to protect nature by transforming production and consumption methods. Since meat production has a significant impact on the environment, alternative meat products should be attractive to consumers who want to transition to a lower meat intake. According to Trewern, meat substitutes must be nutritionally adequate, which is not always the case. She highlighted that around 30% of global greenhouse gas emissions are food-related, and nearly half of those are due to animal agriculture. As the food system is the primary driver of biodiversity loss, transitioning to a plant-based diet is crucial to combat climate change.
In conclusion, mycoprotein is an innovative and environmentally-friendly solution that offers an eco-friendly option to traditional animal-based proteins. Companies like Quorn are leading the way to establish a new standard of sustainability in the food industry. Transitioning to a plant-based diet and embracing the principles of a circular economy can help reduce the food system’s impact on the environment and combat climate change.
