However, the by-products generated by the sorting
units (SUs) and composting units (CUs) as well as by the modern prisms (MPs) are not well understood for the post-2010 operations
in Poland, which meet EU requirements and are biochemically
influenced by low-organic waste deposition. Such reductions in
the disposal of organic matter may limit methane generation by
MPs and the potential use of methane in energy production. However,
many former Eastern Bloc countries have experience managing
MPs and previous prisms (PPs), which were usually ad-hoc
arranged without liners or pollution-control systems and unlimited
disposal of organic wastes.
