Thanks to the operations of the EfWP, waste disposal at the landfill will reduce by approx. 80%. As a result of this, there will be a cut down on disposal sites, and the exploitation period of existing landfills significantly extended. This will bring about a positive effect both on the environment and the local landscape. In addition, significantly reducing the amount of biodegradable waste deposited in landfills will contribute to a reduction in the quantity of biogas produced.
Thermal treatment of waste is one of the most effective ways of dealing with waste; it is, in fact, a rich and inexhaustible source of energy. Waste incineration will be carried out at a very high temperature (above 850°c). This is a guarantee that the process will be completely safe and reduce the possibility of the formation of harmful substances and their further emissions into the atmosphere. The gases resulting from waste incineration will be treated in a modern fume treatment plant. Permissible emission standards shall not be exceeded. Upon launch of the EfWP, residents will be able to track the results of the measurements in the incineration plant on the website: www.odzyskajkorzystaj.pl.
Additionally, during the incineration process, the EfWP produces thermal energy, which is transferred to the district heating, as well as electrical energy that is further transferred to the distribution network of the ENEA Operator. The post-process waste resulting from incineration, among others slags, upon recovery of the ferrous and non-ferrous metals can be used, for example, in road construction.
According to data from the Waste Management Plan for the Greater Poland Province for the period 2012-2017, in 2010, about 273 thousand tonnes of waste was produced in the area covered by the project. In 2013, the amount increased by 12 thousand tonnes. According to forecasts, the amount will increase to approx. 319 thousand tonnes in 2020. For the purpose of the project implementation, the City of Poznan along with the surrounding communes created the Municipal Waste Management Region II, which has been included in the Waste Management Plan for the Greater Poland Province. Residual waste from the area of Region II will be delivered to the EfWP in Poznan.
The newly-designed waste management system, under which the EfWP is being built, shall place a greater emphasis than it is at the moment on the selective collection of waste. This applies to material, green and bulk waste as well as electronic equipment and waste from renovation works, which may be prepared for re-use and referred for recovery or recycling, in accordance with the existing waste management hierarchy for all European Union countries.
Thanks to such a solution only waste unsuitable for material recycling, but suitable for energy recovery (so-called residual waste,) shall be referred to the EfWP. As a result, mixed municipal waste (so-called residual), high-energy ballast waste from clean selectively collected material waste and bulky waste (mainly used furniture) of high energy value shall be referred to the plant.
The EfWP will, therefore, be the last link in the waste management process in the newly-designed system, however, the incineration plant shall not replace, among others; clean sorting of selectively collected waste materials, green waste composting plants and landfills.
