Rehabilitation of Municipal Waste Dumping Areas:
Municipal waste landfills are mainly classified as sanitary landfills and non-sanitary dumping areas. Although non-sanitary dumping areas are rare nowadays, it is necessary to take them under control and rehabilitate them.
On the other hand, sanitary landfills are the impermeable areas with defined boundaries, where wastes are filled under control with continuous monitoring. Rehabilitation and closure of landfills at the end of their life-time with correct methods minimizes their negative environmental impacts.
Mechanical Sorting Plant:
In order to handle mixed collected municipal wastes correctly, they should be sorted into correct fractions. Mixed municipal wastes are made utilizable by classifying them as biodegradable, recyclable and residual wastes via methods based on their sizes, gravimetric and optical characteristics.
Biomethanization is the process where carbon content of the biodegradable wastes is degraded in aerobic or anaerobic conditions and gases consist of mainly methane are formed consequently. Since the goal is to obtain high amount of methane and generate high amount of energy, our plant is operated oxygen-free conditions, i.e. anaerobic conditions. Thus, uncontrolled emissions of oxidized and harmful gases to the atmosphere are prevented. By utilizing methane gas, energy is generated in an eco-friendly way. The most important advantage of biomethanization plants is their provision for obtaining methane gas under closed and optimized conditions in a controlled manner.
Fermented solid material coming out from biomethanization plants is transformed into compost, which can be utilized as soil fertilizer, by passing through some processes like screening, laying and drying in compost plants.
Energy Generation Plant:
Both gases collected from landfills and biomethanization plants are utilized in gas engines where energy is generated. Their operation has details requiring an advanced know-how.
Refuse Derived Fuel (RDF) Plant:
After sorting out biodegradable and recyclable portion of the municipal wastes, we get the residual part consisting of wastes with high calorific values like plastic bags, papers and wood-wastes. This residual part forms the raw material for RDF. They are transformed into RDF by passing through appropriate processes depending on the process they are to be used as fuel.
Class 2 (Municipal Waste) Landfill:
After passing municipal wastes through all processes, the remaining part is the non-utilizable wastes with a fair amount of biodegradable content within them. These wastes are put into sanitary landfills, whose impermeability is ensured via natural and/or artificial impermeable layers. Landfill gas coming out as a result of natural degradation of these wastes is collected by gas collection systems and transferred to energy generation plants.
