Stora Enso is constantly looking for new ways to improve resource efficiency – for the best of the environment and the economy.
Opportunities and challenges
Growing global demand for natural resources, fuelled by population growth, challenges industries to optimise their use of raw materials, water, and energy. This increasing demand may also result in changes in environmental requirements, policies and legislations, or costs.
As a renewable materials company, Stora Enso’s business model aligns well with the concept of a bioeconomy, offering sustainable alternatives to fossil-based materials. Increasing eco-awareness among consumers results in growth opportunities for our renewable, recyclable, and biodegradable products.
How we work
Stora Enso is committed to continuous improvements in resource efficiency. This is done through improvements in the energy efficiency and energy self-sufficiency of our mills, the efficient use of water and other raw materials, waste reduction, the reuse of materials, and the creation of business opportunities from wastes and by-products.
The environmental management work at our mills is supported by third-party environmental management systems. All our mills are certified to the ISO 14001 system, and by the end of 2015, 36 of our European mills to the ISO 50001 energy efficiency management.
Our production processes generate various by-products and wastes, including black liquor, bark, and different kinds of sludge generated during pulp and paper production. Many of these materials are used for our internal bioenergy generation and pulp production, or supplied to our partners for further reuse. In 2015 the waste and residuals reuse rate across the group was 98%, covering internal and external reuse.
While Stora Enso withdraws relatively great amounts of water, only some 4% of that total is consumed in our production processes - almost 96% is recycled back to the environment. The water is released after being carefully purified in our treatment plants (process water), or without treatment (cooling water). Our water use is regulated by the relevant authorities based on local conditions and operational permits.
Stora Enso’s energy supply is managed under long term contracts, direct market access through energy exchanges, efficient combined heat and power production, and shareholdings in power generation companies. We strive to make investments that enable flexibility regarding the use of biomass fuels or other CO2-efficient options. Our central energy efficiency investment fund is one cornerstone of our continuous energy efficiency work.

Our target is to reduce the specific electricity and heat consumption per saleable tonne of pulp, paper, and board by 15% by 2020 compared to 2010 benchmark level. In 2015 this figure was -5.7%.
