Technical Development of Waste Sector in Sweden: Survey

MASTER’S THESIS IN ENVIRONMENTAL STRATEGIES RESEARCH
Qualitative evaluations of the emerging technologies are done by three criteria with certain
evaluation value. Readers are requested to go the methodology section Table 1 for details of the
evaluation criteria. Table 7 shows that, thermal waste treatment technologies have higher
potentials in waste handling, development stage and problem solving capacity. Bioreactor and
sanitary landfill has also potential as emerging technology. Solid waste to protein, slurry curb
process and dry composting are still experimenting in lab scale, which might be developed in the
near future.

Pyrolysis-Gasification is selected as an emerging technology for LCA Model. The main reasons
for choosing P-G for LCA model are:
• It is an advanced thermal treatment process which can manage different type of waste
fractions
• It produces energy which is the leading economical benefit from it.
• Moreover, the emissions data required for the LCA model are available for the P-G
process rather than other emerging waste treatment technologies.
• Potential waste management problem solving capacity of P-G.
