Fiskeby Board - industrial energy recovery from paper reject
Topic of the practice
renewable energy, energy recovery.
Good Practice Information
Fiskeby Board in Norrköping manufactures cardboard boxes for food producers, mainly targeting frozen food. The cardboard boxes is produced from 100% recycled fibre. The companys product is called WLC (white lined chipboard) and is gained from recycled paper, provided by both companies and households. They export roughly 80% of their total 160 000 tons of production, with an estimate turnover of 900M SEK. The companys enviromental agenda stretches further than recycling. To begin with they strived to increase their production while decreasing their enviromental consumption. To decrease the energy and fuel consumption would not only mean decreasing their enviromental imprint, but also greatly reducing two of their biggest expenses steam production and energy from an external source. This is a massive task to execute while your also competing with the other European WLC-producers.
To address the issue of boilers, Fiskeby switched to a combustion boiler instead and started using industrial waste (65%) and their own paper reject (35%) instead. Thus they get paid to handle the industrial waste and re-use it as fuel. Eventually they installed a stream turbine as well, which led to 30% reduction in terms of their external energy usage.
Evidence of success
The company was in a dire economic situation before this practice was indroduced, the high energy costs were a huge burden for the company. Now they are able to: 1. handle their own waste and 2. use it for energy production for their industurial process. They produce 5 MW of electricity and 53,6 tons/h of steam. They cover 40 % of their electricity needs and 100% of their steam needs. They handle around 80 000 tons of waste per year and 75 % of their energy is from renewable sources. The payoff for this investment was 6 years. The company is nowdays one of the leading cardboard manufacturers in Europe.
