Belgium: 100% green energy from 8 million kilo fruit

Belgian company VOS technics has introduced one of the biggest projects of its kind: a heat recovery ventilation system that extracts 100% green energy from 8 million kilo fruit. Last week the invention received the Fructura Award during the Fructura Fair.

Fruit company Hof ten Wijndries used to consume more than 37,000 litres of fuel oil per year to heat 3000m². Precious energy extracted from cooled produce was just vented away. But now, VOS Technics has installed an intricate heat recovery ventilation system able to provide energy-efficient warmth to the entire firm. Energy is extracted from the annually produced 8 million kilos of fruit, and converted into heat by the HRV.

“It’s a system that took 9 months of engineering and 6 months of labour to achieve,” says managing partner Kristof Onckelinx. “To VOS Technics it’s a milestone; no-one has ever done this before.” Total costs hover around 130,000 Euro. But the recipient, Hof ten Wijndries, is likely to earn back this investment in less than 4 years. “Hof ten Wijndries is the first ever company to receive this treatment. But essentially every company working with cooling cells qualifies.”

VOC Technics is a family business specialized in cooling, heating and power. With its 24 employees, it designs and builds installations, not just for industrial refrigeration and ULO storage, but also for heat and the drying of wood.
