Founded over 40 years ago, Enva is a leading Hazardous Waste, Water Services and Laboratory Services provider. We provide services across Ireland and the United Kingdom for the industrial, pharmaceutical, manufacturing, food and beverage and municipal sectors.

Our highly experienced team of 200 managers, engineers, operatives and scientists work closely with our clients to deliver safe, cost-effective, practical and technically innovative solutions to allow previously problematic wastes be processed and recovered into useful new products.

For example, we process and treat waste materials to produce:

  • Clean shredded plastic
  • Alternative fuels for cement kilns
  • Processed fuel oil
  • Flocculants for waste water treatment
  • Organic fertilisers
  • Metals (lead, iron)
  • Inert Soils
  • Clean stone & aggregate

We operate from four EPA licenced facilities, two NIEA licenced facilities, and four fully equipped laboratories, providing innovative solutions to waste management with a focus on recovery rather than disposal and developing a sustainable, circular economy.

In addition to providing treatment and bulking/transfer operations at these sites, we have a dedicated fleet with experienced and highly trained operatives who deliver a range of logistics and onsite services for our customers.

We focus on safety and excellence and are ISO 9001, 14001, and OHSAS 18001 certified. Firm commitments to the safety and welfare of our employees and the environment are a critical component of the Enva identity and a guiding principle by which we operate.

As one of the most experienced waste management companies in Ireland, we pride ourselves in continually meeting and exceeding our customer’s expectations. Enva is part of DCC plc under the DCC Environmental division and adhere to the highest standards of corporate governance and environmental standards.
