The St1 Refinery develops and refines liquid fuels. Situated in Gothenburg, Sweden, the St1 refinery has a processing capacity of 30 million barrels of crude oil per year, or 11,500 tonnes per day, equivalent to around 25% of Sweden's total oil product demand.
The Gothenburg refinery also operates as a blending hub. In addition to the fuel we refine from crude oil in Gothenburg, our partner, NEOT, supplies fuels to fulfil our demand. Our fuel blends contain several bio components that are sourced mainly from the global market with the objective of maximizing the reduction of greenhouse gas emissions. We are constantly aiming to develop and market new products that enable better fuel economy and make less of an impact on the environment. The share of the renewable components we use has increased in recent years as we have incorporated greater volumes of bio components such as ETBE, bio-MTBE and HVO-naphtha.
The products of our refinery include mogas, JET A1, sulphur-free MK-1 diesel and other middle distillates, marine fuels as well as liquefied petroleum gas. The refinery also produces 0.5% S marine fuel, which complies with the IMO 2020 limit that came into force in the beginning of 2020. Most of our refined products are sold through our own St1 and Shell network in Sweden, Finland and Norway.
One of our Etanolix® biorefineries is integrated with St1 Refinery. Its feedstock includes bakery industry and retail waste, packed and unpacked. Biorefinery produces advanced ethanol, liquid animal feed and feedstock for biogas production.
The St1 Refinery was the first in Europe to acquire the environmental certification according to ISO 14001:2015. We set annual environmental objectives and targets for our refinery and closely monitor our progress in achieving them.
The St1 Refinery is also one of the most energy efficient refineries in the world. Most of the refinery's energy needs are met by its own gas production, and nearly a third of the heat generated by the plant is recycled to the City of Gothenburg's municipal heating network to provide heating for some 70,000 homes, enabled by the world's largest waste heat recovery installation.
We systematically develop our operations to ensure low-emission production. Over the past decade tens of millions of euros have been invested in the production of best-quality environmental products and the reduction of production emissions. All of our produced fuels meet the current environmental requirements.
At the St1 Refinery we always put safety first. The refinery has a Health, Safety and Environmental (HSE) Management System in place to continuously improve our work concerning health, safety, security and the environment (HSSE) as well as minimize the risk of incidents.
St1's vision is to be the leading producer and seller of CO₂-aware energy. To achieve this vision, we strive to develop and commercialize functional and environmentally sustainable solutions to replace fossil energy with renewable energy.
The St1 Refinery plays a key role in realizing our vision and fulfilling our long-term advanced renewable fuels strategy. There is a new biorefinery under construction in Gothenburg the design of which will bring flexibility to the process by allowing the use of a wide range of feedstocks. The biorefinery with an annual capacity of 200,000 tons of renewable diesel production is expected to commence its operations in 2023.
