With the aim to explore new horizons for eco-labels and sustainability in the food industry, the Sustainable Foods Summit was hosted in Amsterdam in June. Here are some of the key outcomes of this 11th European edition.
 
Rising market share of sustainable foods. Adoption rates of ethical labeling schemes continue to rise, with over a quarter of all coffee and cocoa now produced according to third party sustainability schemes. Amarjit Sahota, founder of Ecovia Intelligence (event organizer) showed that organic is the dominant ethical label, with sales surpassing $100 billion in 2018. A concern is the proliferating number of ethical labeling schemes could dampen consumer demand. 
 
Economic risks of climate change. Tobias Bandel from Soil & More explained how climate change is affecting soil fertility and crop yields. He called for farmers to reduce economic risks by building farm-system resilience via crop rotation & diversity, green manure & crops, and biomass recycling. 
 
Re-directing food waste. Food waste is a major sustainability issue, with an estimated one third of all food produced going to waste. Al Overton from Planet Organic showed how the retail chain has attained zero waste (edible food) status. It donates surplus food to the Olio Food Waste Heroes programme. In 2018, Planet Organic donated 11 tons of food from its seven stores, helping to provide 55,000 meals to people in need. 
 
Adding social value in supply chains. Sustainability schemes like Fairtrade and UTZ Certified have improved farmer conditions, but have done little to improve poverty levels, according to Julia Gause from FairAfric. The company is “de-colonizing” supply chains for chocolate by producing in Ghana. The company said making organic chocolate in the West African country generates five times higher income for producers than sourcing cocoa alone. 
 
Getting a flavor for plant-based foods. The global market for plant-based foods is projected to reach $5.2 billion in 2020. Givaudan research showed that 52% of consumers stay in the plant-based category because of taste. The flavorings firm called for companies to take a targeted approach when developing products for the diverse consumer groups that now consume plant-based foods. 
 
Power of plant proteins. Heather Mills, public figure and founder of V-Bites, believes the food industry is at the cusp of a plant-based revolution. In her closing keynote, she said such foods provided many solutions to sustainability problems facing the food industry. Her company is ramping up production in order to meet surging demand. 
 
New technologies changing the face of retail. Toby Pickard from IGD outlined the implications of digital trends on the grocery industry. Giving examples, he showed how retailers are having to adapt their physical stores and provide new delivery mechanisms. The future may be with staff-less stores (Amazon Go), drone deliveries (JD.com), and direct-to-fridge deliveries (Walmart). 
 
Ethical egg labeling scheme takes off. It is estimated that up to 6 billion male chicks are culled each year because they are the wrong gender. Martijn Haarman from Seleggt gave details of its new identification technique that prevents the hatching of male eggs. Eggs that remain after using the technique are labeled “Respeggt” and are currently available in Rewe and Penny retailers in Germany. In June, the German Federal Administrative Court supported the new technique to prevent the death of male chicks. 
 
Array of green packaging materials. There is growing investment into sustainable packaging materials, with some new plastic alternatives presented at the summit. Agrana is creating thermoplastic starch from plant sugars; the material is used to make compostable packaging for fruits & vegetables. 
 
Markus Kainer, CEO of the Austrian firm VPZ, showed how it is taking cellulose from wood to make PackNatur, which is used in net packaging. Futamura is also making cellulose-based biopolymers to make compostable packaging. Its NatureFlex material is now used in a range of food and beverage products. 
 
Going plastic-free. There was a call to go plastic-free by Frankie Gillard from A Plastic Planet. According to her organization, over 6.3 billion tons of plastic waste has been produced since the 1950s and only 9% has been recycled. It is encouraging more retailers to follow EkoPlaza and Thornton Budgens and develop plastic-free aisles. Its new Plastic Free Trust mark is given to products and packaging that meet its criteria.
