About us

We also offer a wide range of additional services such as auditing, controlling & sorting waste, life cycle assessments and other sustainability studies. We work according to high quality standards. Over the past 30+ years, we have built up a lot of expertise and are recognized by all certification bureaus worldwide in the field of biodegradable or compostable materials. We actively participate in many certification and standardization committees, as well as European projects and international conferences.

Our history

Normec OWS was originally founded in 1988 as Organic Waste Systems (OWS), a private company under Belgian law. Our headquarters and main laboratories are in Gent (Belgium), while a subsidiary laboratory was opened in 2021 in the USA. We also have long-lasting collaborations with partners in Japan, China, and Korea.

Since December 2022, OWS has been part of Normec Group, which tests, inspects, and certifies so that organizations can innovate safely, quickly, and (cost) efficiently. Hence, we are now called Normec OWS.

Main activities

Normec OWS offers lab & consulting services to various clients from the public and private sector. Consulting services are offered in the field of biodegradation and compostability, waste composition, waste separation, recycling, integrated waste management, and related legislation in both Europe and the US. To this end, we have separate auditing, controlling & sorting, and sustainability assessment services divisions.

Normec OWS also provides contract research laboratory testing for the determination of the biodegradability and compostability of different materials under strict quality-controlled conditions.
