Asia-based biofuels company EcoCeres has partnered with waste management firm Shenzhen Expressway Environmental to source waste feedstock.

As part of the agreement, the companies would collaborate in the collection and transportation of used cooking oil (UCO); waste oil, pre-treatment and processing; production of renewable fuels; circular economy utilisation and carbon reduction, EcoCeres said on 30 November.

EcoCeres said the partnership would source and provide it with a stable and high-quality feedstock source with International Sustainability & Carbon Certification (ISCC) traceability.

Shenzhen Expressway Environmental has more than 20 kitchen waste treatment programmes across China, processing more than 7,000 tonnes/day of kitchen waste.

As part of the partnership, Shenzhen Expressway Environmental would supply UCO and waste oil from its kitchen waste treatment facilities under a long-term contract to EcoCeres, which would then be converted into hydrogenated vegetable oil (HVO) and sustainable aviation fuel (SAF), EcoCeres said.

According to its website, Hong Kong-based EcoCeres processes biomass wastes into biofuels and biopolymers. In addition to producing HVO and SAF at commercial scale, the company produces cellulosic ethanol, a petrol blend-substitute.

China is the world’s largest producer of UCO, with expected output of around 11.4bn litres last year [2023], according to the US Department of Agriculture (USDA).
