Oversize materials from the 80 mm rotary drum sieve are transferred by conveyor belt to a hand-sorting unit in order to separate recyclable materials. MSW from the districts that have high income and use gas or liquid fuel were intended to be transferred to the plant. The non-source separated waste processing facility, which utilizes mecha- nized sorting equipment and workers to pick recyclable material out of the refuse, was designed according to the recommendations in the feasibility reports. General health and safety precautions are taken for workers, such as gloves, vaccinations, etc. No health problems have been reported in the plant that was directly related to waste picking [8]. The composting and recycling plant was constructed to produce compost material for the municipality’s parks and green areas, but not for sale. There is almost no mar- ket for compost material from solid waste; one of the rea- sons is the lack of compost plant in Turkey until recent decades. Analyses pH, moisture content, organic matter content, TKN, total phosphorus (TP), total organic carbon (TOC), C/N ratio, phytotoxicity, Salmonella sp. test, Stability Index (SI) and heavy metals (cadmium, chromium, copper, nickel, lead and zinc) were analyzed to determine end product quality. Solids analysis requires finely ground homogeneous sam- ples. The samples were ground in a grinder to pass a 1.5 mm screen after drying. Thereafter, pH, organic matter, TOC, TKN, C/N ratio, TP parameters were analyzed according to Standard Methods of APHA [9]. While a product may not negatively impact plant growth in the short term, over time it could become phy- totoxic due to the build-up of inorganic materials, which could potentially lead to a reduction in soil productivity.
