After graduating in economics and business administration Volkert worked for Cargill Inc USA before founding Eosta www.eosta.com in 1990. The Dutch company is presently Europe's largest and fastest growing importer, packer and distributor of organically grown fresh produce and serves major retailers and natural food stores in Europe, the USA, Canada and the Far East. Eosta runs warehouses and pre-packing facilities exclusively dedicated to organic products in Europe's main fresh produce centres.

All Eosta products carry a unique Nature & More ‘trace & tell’ (QR) code that provides retailers and consumers with direct web access to the unique story of the producer as well as to the ecological and social impact www.natureandmore.com.

Eosta was the first to obtain carbon credits on organic farming practices www.soilandmore.com.

During the 2015 United Nations Year of Soil Eosta launched the Save Our Soils campaign, together with FAO, 200 partners and many VIP’s amongst whom Desmond Tutu, Julia Roberts, the Dalai Lama www.saveoursoils.com.

Recently Eosta launched the True Cost of Food initiative. It promotes the principle that food prices should reflect the true cost of food, including hidden environmental and social costs. While international policymakers are still discovering the promise of full cost accounting, Eosta takes True Cost to the shop floor. The True Cost of Food transparency initiative shows consumers the true cost of organic vs conventional products http://www.natureandmore.com/the-true-cost-of-food-how-it-works

Eosta, Soil & More and Nature & More have been awarded with various prizes such as the Nr 1 position at the 2017 Dutch Sustainability Top-100, the King William I Award 2018 and the European Business Award for the Environment 2018.
