About Dunwell

Stand for advanced technology, high quality and excellent customer services. From a single trade of machinery with a handful of staff to a multi-faceted corporation of over 100 employees, Dunwell has captured the booming of Hong Kong’s economy.

Established in 1969 by chairman Mr Chow Cheng, Dunwell has since evolved and become synonymous with state-of-the-art environmental services, cutting-edge research and technology, continuous innovation and dedicated customer support. A multifaceted corporation with over 100 employees, Dunwell has contributed to Hong Kong and regional industrial and economic development over the past decades by providing the environmental and resources recovery services that are essential for a better, more sustainable future.

Today, Dunwell’s diverse portfolio ranges from industrial liquid and chemical waste management and municipal water treatment, to green products and services and the provision of environmental technologies and oil analysis services. We aspire to lead the regional market by applying innovative technologies across the entire waste management value chain.

Dunwell’s 100,000 sq-ft site in Yuen Long, Hong Kong is one of the largest independent and advanced waste oil treatment and recycling plants in Asia. As well as wining numerous industry awards, Dunwell embraces a proud pioneering legacy as the first company accredited by the Hong Kong Institution of Engineers to train professional Scheme ‘A’ environmental engineers.
