About us

Kwaliflex Food Recycling is one of the largest processors of residual waste streams from the food and beverage industry

Kwaliflex is one of the largest suppliers of green power through the use of bio-fermentation in the Netherlands. Kwaliflex Waste Solutions specialises in proactively taking all matters pertaining to their waste streams out of our clients’ hands.


The organisations that make up the Smits group are divided between multiple business units.

Besides the activities conducted under the banners of Kwaliflex Food Recycling and Kwaliflex Waste Solutions, our bio-fermentation and animal feed divisions also form two separate units. Despite this division, the various units work together closely with regard to operations, the resources market, purchasing and sales. The businesses in the Netherlands are all located in the vicinity of the estate. The estate itself comprises 540 contiguous hectares and serves as the historical home base of the businesses in the Smits group.


Kwaliflex primarily operates in the Benelux and Germany.

In the UK, we operate under the brand name QBS (Qualiflex Biproduct Solutions).
