Solid Waste Treatment

Current practice in Indonesia shows that Household Solid Waste (HSW) is handled by transferring to landfill site. Meanwhile, around 68% of HSW is composed of biodegradable components, which has potential for biogas production. The current study compares some commercial activators including Green Phosko (GP7) and Effective microorganisms 4 (EM4) with homemade activator in 200 L anaerobic digester equipped with manual mixing for processing kitchen waste (KW). pH and ratio of solid waste to water were set at 8 and 1:2, respectively. Batch experiments show that digester #3 with homemade activator shows superior performance compared to commercial activators. Meanwhile, the digesters with commercial activators show better performance compared to digester control (without activator). Digester #3 produces 1.35 L CH4/kg total solid (TS) and 1.14 L CH4/kg volatile solid (VS). Current work suggests that the homemade activator has the most suitable methanogen bacterium compared to the commercial activators.

<p>This study aims to analyze the existing conditions of the solid waste management system in Pasaman Barat Regency and discuss the alternative development of solid waste management systems with a solid waste treatment approach At the regional and municipal scale as a solution to the problem of solid waste management in  Pasaman Barat Regency. From this study it is known that the level of existing solid waste management services was  only 9.13% of total solid waste generated. The problems faced in solid waste management in Pasaman Barat Regency were still high levels of unserved solid waste, inadequate operational facilities and infrastructure for solid waste management, uneven handling of solid waste in service area coverage and the low practice of waste minimization and utilization. The solid waste man-agement system in Pasaman West Regency in the future can apply a combination of solid waste manage-ment approaches at the regional level based on Solid Waste Treatment Station with reduce-reuse-recycle approach (TPS 3R) in domestic areas and treatment at the city level based on Intergrated Solid Waste Treatment Station (TPST) at the landfill site, with the development of the system planned for 15 years, solid waste volume taken into the landfill site can be reduced by 22.40%</p>

Biowaste Treatment

Vegetable fruit garden wastes were treated anaerobically using a multistage Dranco system. The digesters were composed of three 50 L vessels kept in mesophilic conditions. They were operating at 14.5-17% TS. By controlling the pH in the system, the start-up for biogas production was shortened to 60 days. The pH correction was a buffering which enhanced methanogenic activity in the digesters. With a loading rate of 4.1 kg VS/m3reactor.day, the production of biogas was 5 m3/m3reactor.day, and 60-70% methane content. This allowed making a multisystem by starting every 3 weeks with new vessels in order to maintain biogas production, to be used in industries or in local communities in low-tech countries. The designed model was started in Kinshasa (Congo) where a project is expected to treat one ton of solid waste on a daily basis, for a production of 100 m3 biogas. This cost effectiveness of the system is demonstrated and presents the opportunity for biowaste treatment coupled with environmental protection and substantial energy recovery.

Solid Waste Treatment

Solid waste management is one of the most important challenges for the local administration in Pleiku city. The study on current assessment and proposing solid waste control solutions was con-ducted in Pleiku city, Gia Lai province. In general, the large volume of the municipal solid waste caused pollution and loss of ecological beauty - case study in Pleiku city. This paper investigated the total solid of waste volume which was increasing in periods from 2012 to 2016 with 35,386; 38,689; 43,243; 46,900 and 50,737 tons per year, respectively. The amount of solid waste was col-lected mainly from households and they was equal to the highest rate of 78.7%. Regarding to prediction by 2030, the volume of municipal solid waste tends to increase with 361.186 tons per day. The solid waste was buried in a landfill and used a large land area, but it just can be used in a short time. In addition, the volume and composition of municipal solid waste were relevant to the MBT-CD.08 technology's standard. This researching will be contributed to the decision-making on the selection of solid waste treatment technology in Pleiku city following their trends such as the sustainable development and the high benefits. The MBT-CD.08 technology are a useful solution, high feasibility and will be saved costs related to the solid waste treatment.
