Waste & Circularity

We apply the waste management hierarchy when dealing with business, production and chemical waste*. Our priority is to avoid or minimize waste generation in the first place. If this is not possible, we look to recycle, recover or reuse the waste. As a last resort we opt for disposal by incineration, without energy recovery, or landfill.

*Innospec does not directly disturb land or generate tailing waste.
  • Total Waste
  • Waste Handling Routes
Compared with 2024, total waste intensity increased by 5%, with hazardous waste intensity rising by 8% and non‑hazardous waste intensity by 3%. Reported waste data includes routine production waste as well as non‑routine streams such as construction, demolition, and the removal of aging stock, which can result in year‑to‑year variability. The increase in 2025 was primarily driven by one‑off non‑routine activities including construction and infrastructure projects, site upgrades, and the clearance of aging raw materials and stock.
In 2025, 52% of total waste was sent for reuse, recycling or recovery, 29% for other treatment or incineration without energy recovery, and 19% to landfill.

Reducing Our Waste

We have introduced a number of initiatives to reduce waste across our sites and prioritize recovery and reuse, with the aim of contributing to the development of a circular economy. See some of our sites’ recent activities below.

Barcelona, Spain

At our Barcelona site, we optimized the packaging of our product Enviromet 5669 by transitioning from drums to intermediate bulk containers (IBCs). This change increases payload efficiency, allowing more product to be transported per shipment while significantly reducing packaging material. This initiative is expected to deliver an annual waste reduction of approximately 2.14 tons.

Midland / Pleasanton, US

These sites now use a third-party company to collect and recycle alkaline (AA, AAA, etc.) batteries that were previously thrown away. These batteries may otherwise leak hazardous materials into landfill sites and eventually groundwater if not properly disposed of or recycled.

Castiglione, Italy

To reduce wastage caused by the periodic sampling of a production process and drainage of tank lines, the site has implemented a new product recovery system. The collected material is tested and then recovered into the next production batch of the product. This is avoiding 12 tonnes of product from being sent for waste treatment each year and also reduces raw material usage.

Salisbury, US

The site has upgraded the device that removes pollutants from our industrial exhaust stream, avoiding the generation of Hydrochloric Acid, a hazardous waste material. This new equipment for our existing process will save 270,000 pounds of hazardous waste every year.

Midland / Pleasanton, US

The sites are returning oil and water samples from our analytical labs back to customers once testing is complete, preventing it from being sent to landfill and benefiting the customer.
