Like other Cities in Indonesia, Kota Probolinggo also faces municipal solid waste problems. To overcome it, Kota Probolinggo is trying to do activity of garbage recycle at household scale and also in neighbour scale. One of the efforts is converting it to become organic fertilizer with a good quality, a real fertilizer required by the farmers to improve soil fertility which becoming decreases. To support the activity, in year budget 2008/2009, Pusat Teknologi Lingkungan - BPPT has done a disemination technology of Accelerated Revolver Windrow Composting (ARWC) for optimization of composting which have been done in Kota Probolinggo. Technology ARWC was developed by BPPT which has been checked and tested. Technology ARWC is fermentation system of organic garbage done aerobically by the way of heaped (windrow) and revolved regularly, turns into stable matter like humus in accelerated time. The product is compost, either in the form of ordinary compost and also compost granule, with a good quality and fulfi lls national standard. Processing activity of garbage becomes organic fertilizer has opened new employment and increases management system effi ciency and lengthens TPA age.Key Words: Municipal solid waste, Composting

Abstract Production of refuse derived fuel from municipal solid waste in future shall play a strategic role in an integrated waste management system. The amount of landfilled biodegradable materials thus will be diminished according to provisions of the 1999 Waste Landfill Directive. The aim of this article is to evaluate cost effectiveness based on cost evaluation of the different complication of the waste pre-treatment equipment complectation and based on regenerable waste quantities in Latvia. The comparison of cost estimates is done in 3 scenarios considering potential waste quantities in Latvia: Scenario I - planned annual waste quantity is 20 kT; Scenario II - 40 kT and Scenario III - 160 kT. An increase in amount of waste and processing capacity means the decrease in costs of mechanical pre-treatment of 1 ton of waste. Thus, costs of mechanical sorting line under different scenarios with capacities of 10 t h-1, 20 t h-1 and 80 t h-1 are EUR 32 per t, EUR 24 per t and EUR 15 per t, respectively. Most feasible cost for a set of mechanical pre-treatment equipment for the capacity of 10 t h-1 is EUR 32 per t by using rotating drum screener with the following manual sorting. Mechanical pre-treatment equipment of unsorted municipal waste is economically nonbeneficial, when the use of fine (biologically degradable) fraction is not possible. As the sorting of biodegradable kitchen waste is not developed under the current waste management system in Latvia, the lines for mechanical pre-treatment of household waste would be better to install in landfills.

The article deals with the management of municipal solid waste in accordance with the reform. It is proved that the waste processing industry needs fundamental changes. It is proved that the effectiveness of the reform of the municipal solid waste management system can be assessed using an optimal financing model based on a scenario approach.

Twenty years of formal private sector participation in solid waste management in Ghana has failed to deliver an increase in collection coverage and recycling rates. This article shares lessons and experiences from Accra, Ghana, a middle-income city where researchers and municipal solid waste managers have collaborated to modernize the municipal solid waste management system by working together to develop a locally appropriate response to the informal waste service sector. Stakeholders have used inclusive decision-making and participatory research methods to bring formal service providers to work in partnership with their informal counterparts to improve collection and recycling. The Wasteaware benchmark indicator framework has been used to assess and compare the improvements in the physical and governance aspects of the municipal solid waste management system, supplemented by statistical analysis of responses to a survey on the socio-economic contribution of the informal service providers in the city. Within two years of their inclusion, the number of informal service providers has increased by 71 percent, from 350 to 600, creating new livelihoods and contributing to poverty reduction. The informal service providers have been able to increase collection coverage from 75% to 90%, waste capture from 53% to 90%, and recycling rates from 5% to 18%, saving the municipality US$5,460,000.00 in annual operational costs. The results have influenced the decision-makers to move towards structural integration of the informal service providers into the formal waste service system. The shift towards practical, locally responsive interventions in Accra provides a positive example of sustainable waste management modernization, and key lessons for cities in similar economies.
