Sludge pyrolysis in the Halland region, a pre-study
Pyrolysis as an innovative and sustainable solution for sludge management? Logistics, economics, regulations and benefits for agriculture have been investigated in this feasibility study based on conditions in the Halland region.
Interest in thermal treatment, e.g. pyrolysis, of municipal sewage sludge has increased in Sweden in recent years. For smaller wastewater treatment plants, an investment in pyrolysis may become more attractive if cooperation between plants is established and the treatment is carried out regionally.
This study investigates the conditions for pyrolysis of sewage sludge in the Halland region. The study maps existing sludge volumes in Halland and investigates potential benefits of using sludge biochar in agriculture. Also, regulations relevant to the pyrolysis of sludge and the use of sludge biochar are analyzed, as well as the economic conditions for pyrolysis and related sludge logistics.
