Introduction
Waste is the result of discharges from a production process both industry and domestic (household) which is considered to have no use value anymore. Solid waste or can be called as waste consists of chemicals, organic compounds, and inorganic compounds that adversely affect the environment, especially humans so it needs for special handling to solve solid waste problems.
Solid Waste Issues in Indonesia
In Indonesia, there are some issues concerning the handling of solid waste in certain areas, such as those in Sumatra, Kalimantan and Papua resulting from the exploitation of mineral resources by mining companies that make the area polluted by unnecessary minerals and waste derived from the process of mineral ecstasy using hazardous chemicals.
Environmental Issues in East Java
Environmental issues occurring in East Java include: Management of forests, land, and water resources; Coastal and marine issues; Problems of water, soil, and air pollution; Urban environmental issues; and social issues.
The most important environmental problems in urban areas are the problems of waste management, flooding, motor vehicle emissions, domestic wastewater, lack of green open space (RTH), urban spatial arrangement and so on. As an example of solid waste management, garbage production in Surabaya is collected at landfill sites, namely: Sukolilo TPA and Benowo TPA, which has caused social conflict. The average garbage production in Surabaya is 8,700 M3 / day or 2,436 ton / day, while garbage production in Gresik is an average of 1,580 M3 / day or 442.45 ton / day. This is coupled with an improper management system, namely 'open dumping' rather than 'sanitary landfill', resulting in limited landfill age, liquid leachate pollution, and must provide new landfill sites (Pusat Data Lingkungan Jawa Timur).
East Java Provincial Government (Pemprov) will start construction of waste treatment facilities next year. The facility will accommodate 30 percent of the 170 million tons of waste that comes from industrial waste, motor vehicles, households, laboratories, and hospitals.
The waste treatment facility will have three main functions, which are utilization, management and landfill. Initially operating, the facility will accommodate solid waste. Technologies used include inseneration, solidification, land fill and utilization. technology development and management of the facility will be carried out after the next five year.
