The Role of Informal Collectors of Recyclable Waste and Used Goods in Indonesia

Development of an Ex-Ante Sustainability Assessment Methodology for Municipal Solid Waste Management Innovations

“…The share of inorganic waste (paper, plastic, metal, glass textiles, and rubber) is 35.7% [58]. It is found that the recycling of textiles and rubbers is not common in developing countries [39,59].

Due to contamination from waste produced by so many stakeholders, the water becomes unhealthy for consumption by people [27,28], especially with the reduction of open space and the growth of pollution [22]. In order to maintain the purity of the water content and the availability of clean water it is necessary to balance the natural ecosystem and preserve the environment from the damage caused by industrial pollution, pollution, household waste and excessive water use.…”

The Factors Influences of pH or Acidity Level in The Urban Area

“…In such circumstances, water is one of the commodities that need to be considered, because it involves a very vital human need. If the water is polluted, and has a pH value below normal due to contamination from waste produced by industries, households and transportation, the water becomes unfit for consumption by local people [5,8] especially according to the open space to reduce pollution [9]. In the other hand, some studies have been reported regarding to these urban pollution and surrounding it in separated research [10][11][12][13][14][15].…”

“…This city has an area of 118.50 km 2 , a population of 1,030,720 million inhabitants with a density of 8,019/km 2 . It is geographically close to the capital city of Indonesia, Jakarta, making it a strategic city in the development and growth of economic activity [4][5].…”
