EFO AB was founded in 1975 as a joint venture of 10 Swedish energy companies, to capture scale effects in the business of oil imports. Today the rational of the business has dramatically shifted as the industry has moved away from its dependence on oil, in favor of energy recovering from waste materials.

A complex flow of waste and energy – made easy

In the global society, as we know it today, waste is contantly being generated. As the consumption increases, so does the waste. The only question is how we take care of the waste being generated. On a global basis that is. Because waste really is a global matter – not a local matter.


Some of the waste that we generate every day, can be recycled into new products, and that is probably the best way to handle waste; to let it back into the cycle of production. Some of the waste we generate is hazardous and has to be taken care of in special and controlled ways, but a lot of the waste being generated worldwide can be used as fuel to both create electricity and to heat homes and businesses.


But this capability, to use certain wastes as fuel does not apply everywhere. In most countries, you burn waste without taking care of the heat and energy that’s being generated when burning. Fortunately, in Sweden, we have been able to turn the heat and energy that’s generated from burning waste for the last five decades. In most Swedish cities, district heating is the main source to heat homes and this method needs a constant flow of materials to work. This is where waste comes in. And for us in Sweden, waste is not only a problem – it is an opportunity; treated in the right way of course.



At EFO we have been relocating waste for over twenty years. And as the growing amount of waste in a global issue, there isn’t any question of who’s waste it is. It’s our waste – our as in everyone living on this planet. But hold on, some might say – isn’t that bad for the environment, to transport waste from one country to another simply to burn it? Quite the contrary actually, as we in our case only use the never-ending imbalance in existing freight ways. When someone – a train operators or a sea freighter for example, is to go empty on the way back from delivering goods, we fill it with waste, from which we can create heat and electricity.



But haven´t we got enough waste ourselves you might think? The simple answer is no. Well, for sure our forest industry creates a lot of fine waste to be used, and also the building industry generates a lot of “good” waste. But as we are getting better and better recycling most of our waste and as we live in a rather cold country, we need to bring in fuels to burn during the winter. Because one thing is sure; we can’t risk to not be able to heat our homes and supply critical businesses with electricity. So therefore, we import waste from other countries, where the climate is not as cold as in Sweden and where the possibility to use waste as fuel simply doesn’t exist.


We live in a global world, where the whole world is connected. Goods and people travel back and forth all the time and therefore it is not fair to talk about who’s waste belongs to who. The challenge of the ever rising amount of waste is everyone’s challenge and as we are able to make something good out of waste, we should continue to do so. Sounds fair, doesn’t it?

All partners in EFO; both owners and suppliers are a part of the EFO community, where sharing and exchanging information both makes us stronger individually and as a group. 


Thanks to our solid network, we are able to quickly adopt and adapt and thus not only improving the everyday business but also affecting the market surrounding us. 


This helps us reach a higher level of stability and helps all our hard-working employees widen their insights. Important for Sweden, as Sweden is completely dependent on importing residual waste – and important for all partners in our network, as it creates value for anyone in it.

We produce district heating for about 300 000 people, offices, and industries in the Stockholm region, around the clock, all year. In our plant, we also produce an amount of electricity equivalent to the use in 100 000 households. It is sold directly to the Nordic power exchange. In one year we transform One million tons of waste into energy. Half of it is shipped to us in our Södertälje harbor. The production takes place in our three different plants – Igelsta power heating plant, Igelsta district heating plant, and the Fittja plant. Learn more at www.soderenergi.se

Our main fuels

Refuse derived fuel (RDF)

Refuse derived fuel pellets, or energy pellets, can be produced from these cleaned and sorted recycled materials after further processing.

Waste Wood (RWW)

Recycled wood is obtained from the construction or demolition of buildings, as well as from scrapped pallets and furniture. 

Forest Wood Residue (FWR)

Forest wood residue is made from materials collected directly from forests. Forest management results in dead or decaying stems as well as those trees that have been thinned out.

Closing the loop

The circular “take-make-consume-reuse-recycle-recover” economy implies that we recover the materials and energy from discarded products. When a product reaches the end of its life, materials and energy are kept within the economy, so that they can be used again and again, thereby creating further value.
