year on year until 2032. As part of this obligation, the RTFO also requires that a growing percentage of biofuel must be classed as development fuels to receive Development Renewable Transport Fuel Certificates (dRTFCs). dRTFCs are defined as new types of advanced biofuels made from sustainable wastes and residues. They are required to have a GHG savings threshold of at least 65% and have been introduced to incentivise innovation, such as our waste tyre project. Conclusion Greenergy’s GTT is a platform to transition into the next generation of waste utilisation, creating value, producing circular products for industry, and producing low-carbon fuels. It shows how we can further support our customers through the energy transition and contribute to the circular economy by undertaking projects that reduce and recycle wastes to create new forms of next- generation renewables for use in the transport sector and wider economy. By utilising expert technology suppliers and experienced engineering companies, we are creating projects that can be delivered and truly help to decarbonise fuel and other industries. * thyssenkrupp Mining Technologies GmbH was acquired by FLSmidth A/S on 31 August, 2022. All “thyssenkrupp” and “tk Mining” brand names will be replaced by “FLSmidth” during 2022.

The solids product is a char, largely made of pure carbon, which is further processed through milling and pelletising into a high-quality carbon black, which can then be reused in the production of new tyres and other rubber products, supporting a circular economy. As shown in Figure 1 , the plant will additionally process used cooking oil (UCO) and tallow into sustainable aviation fuel (SAF) or hydrogenated vegetable oil (HVO) and bio- naphtha with relevant supply and off-take agreements with Greenergy, further supporting the decarbonisation of transport. The two hydroprocessing units are complimentary to one another and will leverage shared infrastructure and Greenergy’s expertise in UCO supply and processing to create opportunities for efficiency gains and cost reduction. The GTT project will be the largest waste-to- renewable fuel facility in the UK and will be built on 40 acres of reclaimed land at Seal Sands, near Stockton on Tees in the North East of England. The area is already a hub for renewables, and the site is near one of Greenergy’s existing biodiesel facilities and the adjacent fuel terminals and import/export infrastructure. The facility is due to be operational in 2026. Regulatory environment In the UK, the percentage of sustainable biofuel that fuel suppliers are obligated to blend into their gasoline and diesel is mandated under the Renewable Transport Fuel Obligation (RTFO), and that percentage will continue to increase
