Sustainability is in our DNA. It is integral to everything we do. From the raw materials we source and the way we use them, to the ingredients we create, we believe in being a responsible company. We are pleased to introduce our new ECO range of 100% bio-based surfactants. Over 50 products make up the ECO range made by using bio-based ethylene oxide (EO) which we manufacture from biomass ethanol. Coupling the use of bio-based EO with the high proportion of renewable energy used at the manufacturing plant, leads to a significant reduction in carbon footprint for the ECO product range. Formulators can now access 100% renewable surfactants without sacrificing performance to help meet increasingly demanding sustainability targets.
The new range of ECO surfactants
- 100% renewable
- Performance identical to petrochemicalbased options
- Lower carbon footprint than petrochemically derived ingredients
- USDA BioPreferred®Program third party certification
- RSPO Supply Chain Certified via Mass Balance
- Made using renewable energy
The ECO range provides multi-layered renewable benefits and value for our customers. Not only will formulators be able to replace petrochemical-based non-ionic analogues while experiencing “zero sacrifice” in performance, they will be able to replace less-effective “natural” market alternatives as well.

In 2012, we invested in a renewable energy project at our Atlas Point manufacturing site located in Delaware, USA (Figure 3). This investment saw the installation of a 3.5 mile pipeline from a local landfill site so that we could purchase local landfill gas. The gas feeds two combined heat and power (CHP) units and a multi-fuel boiler to generate electricity and steam for the plant. In 2014, we further invested in solar panels at the site, which reduced our annual carbon dioxide (CO2) emissions by 11,600 tonnes CO2e. By quarter two of 2020, a third CHP unit will be installed, increasing our capacity for generating electricity and steam from landfill gas and increasing the estimated percentage of the site’s energy being renewably sourced to above 30%.

Technical Details & Test Data+
With increasing consumer demand for renewably sourced and sustainable products, we are pleased to introduce our new ECO range of 100% bio-based surfactants. In recent years, “greener” non-ethoxylated ingredients have been used in the pursuit of more renewable formulations, but the performance has not met the levels achieved when using traditional ethoxylates. With significant investment at our Atlas Point manufacturing site, located in Delaware, USA, our plant is the first of its kind in the US to produce bio-based EO from bio-ethanol (Figure 3). This development enables the production of sustainable and bio-based ethoxylates (Figure 1).

Our new ECO range helps formulators meet renewability targets. Table 2 lists the BioPreferred bio-based content requirement of a finished formulation under a product category. Replacing petrochemical based surfactants for ECO range products will improve bio-based content of the formulation. All ECO products are being registered on the USDA BioPreferred Programme.

Converting landfill gas to electricity and steam avoids the release of methane into the atmosphere, which has a global warming potential 25 times greater than CO2 when measured over 100 years. Our use of landfill gas since 2012, combined with the reduction in our usage of natural gas, has led to an aggregate reduction in GHG emissions of close to 1 million tonnes CO2e. Annually, the amount of avoided emissions is a figure equivalent to our total combined Group 1 and 2 emissions.
Chemically equivalent to petrochemical-based ethoxylates, Table 1 shows the improvement in bio-based content for key surfactant chemistries when produced using our bio-based EO.

We have used SimaPro software to model the cradle-to-gate life cycle analysis (LCA) of our ECO product families, focused on the climate change impact category, following the technical specification ISO 14067. The high proportion of renewable energy available at Atlas Point, along with the use of bio-based EO, leads to a significant reduction in carbon footprint for a typical ECO product family, when compared to traditional ethoxylates made using petrochemical-based EO and without renewable energy (Figure 4).
