Carbon and climate efficient use of biogenic waste for circular chemicals

In Sweden, around 7Mton of waste is yearly incinerated for energy recovery. Currently around 60 % of the carbon available in that waste is biogenic. Meanwhile, the demand for green carbon is expected to increase as industry transitions to mitigate climate change.

This project assesses using the solid waste streams to produce platform chemicals, thereby utilizing the green carbon in the waste. At present, the main alternative to decrease climate impact of waste treatment is (BE)CCS. However, depending on the type of end-product and the background system, using the carbon in waste to produce circular chemicals might be a better option.

To identify the viable scenarios for utilization of waste to chemicals, a holistic perspective is required. Here, the climate-, cost- and policy perspective of producing platform chemicals from solid waste fractions via gasification or incineration coupled with (BE)CCU, will be assessed. The results will be of great value both to industry and authorities.
