The waste bank is an alternative waste management in Indonesia. The waste Bank in Gunung Kidul Regency, Yogyakarta is one of the waste banks that has been established and is active until now. The method used to determine the generation and composition of waste is SNI 19-3964-1994. In addition, research data are obtained by observing and interviewing directly in the field, then analyzed by quantitative descriptive. The results showed the average rate of waste generation in Gunung Kidul Regency was 0.48 kg / person / day. The highest composition of waste in Gunung Kidul Regency is organic waste, which is 77.61%, while non-organic waste is 22.39%. At present, the Waste Bank in Gunung Kidul Regency is able to reduce waste by 0.86% with a total of 6,423 m3 / year reduced waste. The benefits of the existence of a waste bank, among others, are in the field of waste management, in terms of economic and social aspects. The potential for waste recycling is 17.49% from 22.39% of the total non-organic waste.

Bandung City is one of the big cities in Indonesia that grappled with waste problem. There is 1,500 ton of waste produced daily, of which 65% is organic. In addition, the water content of the waste could reach 80% during rainy season, given that the waste is commonly collected in open space before transported to the final disposal area. In order to tackle this issue, the municipality of Bandung has started to implement anaerobic digesters to treat kitchen waste since 2013 in an attempt to reduce organic waste. There are three scales of bio-digesters that have been implemented: city 2 ton, communal (20-1000 kg) and household scale (20 kg), which comprise of 1 unit, 15 units and 100 units respectively. This study evaluate the efficiency and biogas productivity of each bio-digesters type. We analyzed 30 unit and 14 unit of household and communal biodigesters respectively. The waste input, slurry output and biogas production were estimated based on average of daily basis. Both the input and output of the biodigesters were characterized (TS, VS, COD) to gain further understanding. This study provide facts and figures to improve the further implementation of household bio-digesters in Bandung City.

Abstract This study presents solid waste management planning in an urban green area, Bangkok, Thailand based on the material flow analysis (MFA) and life cycle assessment (LCA). Global warming potential (GWP) of four scenarios for handling solid waste generated in Chulalongkorn University Centenary Park, 2018 was assessed concerning the different ratios of waste recycling, composting, incineration, and landfilling. The results show that alternative systems proposed will result in lower GWP than the existing waste management strategy. The MFA results reveal that the final weights of solid waste ending up in a landfill are 98.8, 101.9, 68.2, and 44.8 t yr− 1 for scenarios 1, 2, 3, and 4, respectively. Increased rates of landfill diversion by increased recycling, composting, and incineration decreased the quantity of solid waste disposed to the landfill and improved the environmental profile of the park waste management system. The LCA results found landfilling to be the dominant source of greenhouse gas (GHG) burdens, while waste recycling was found to result in the reduction of GHG. The results highlight that the use of MFA and LCA as a combined tool to evaluate the environmental performance of solid waste management systems provides valuable information for policy and decision-makers.

Abstract Trees in urban green space areas serve not only aesthetic purposes but also various ecological functions, including filtering air pollutants, improving groundwater quality, and generating biodiversity of flora and fauna. However, the presence of urban Urban Green Space (UGS) must equal 30% of the urban area, which is still constrained by regulations and community participation. Therefore, this paper aims to capture an overview of the existing UGS in several regions in Indonesia by using qualitative methods., which included over ten locations in Lampung and several cities throughout Indonesia for comparison, yielded several findings that can hopefully be used to inform the development of UGS policies. The findings demonstrate the numerous benefits of open space, particularly mental health, nature conservation, social interaction, and economic development. The critical nature of UGS, particularly in regencies/municipalities, requires increased awareness and effective management by involving as many stakeholders as possible, including the private sector and the community as users. The implication of this research is, in a sustainability context, with the need to instill sustainable behavior in users and to stimulate economic growth, a business model based on environmental stewardship is required, specifically the circular business model
