Abstract This paper presents the characterization of municipal solid waste (MSW) randomly collected from two Material Recovery Facilities in São Paulo city, before (input - recyclables) and after (output - rejects) the sorting processes. Geo-environmental and geotechnical tests were performed on shredded samples and a digestion method was applied to detect the metals As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn concentrations using ICP OES. The objective was to assist future activities of integrated solid waste management and soil pollution. Results showed different particle sizes comparing the input (44.6%) and the output MSW (75.1%) passing through the 100 mm sieve. Organic matter and ash contents indicated the influence of inorganic carbon due to plastics' presence, with values varying between 6-13%. The pH values obtained were neutral and the electrical conductivity of the MSW rejects suggested a higher amount of ions, with values above 1000 µS/cm. Metals analyses show that Cd, Cu, Ni, Pb, and Zn are present in high concentrations, depending on the types of the materials. Standard Proctor compaction curves yielded maximum dry unit weight varying from 6.6 kN/m³ to 10.0 kN/m³ and optimum moisture contents from 20–42%. Cohesion ranged from 1.3 kPa to 31.3 kPa and friction angle from 3.2° and 42.9°. The results are comparable with those obtained for other countries using different MSW treatments and contribute to the data basis for MSW from the selective collection, aiming the integrated solid waste management, serving for other countries that adopt MSW sorting and recycling.

Quantification and characterization of municipal solid waste are vital information for a proper solid waste management. However, these are under-investigated and scarcely implemented in Laos PDR, especially the local communities. This work, therefore, aimed to quantify and characterize municipal solid waste generated from Beung Kiat Ngong Ramsar Site and to recommend possible integrated solid waste management strategies for a sustainable waste management. The average daily waste generation was estimated to be 3.6 kg/day and 2.6 kg/day in Thabou village and Kiat Ngong village, respectively. Organic waste appeared to be the biggest component (28%) for Thabou village, while packaging’s dominated waste composition in Kiat Ngong village. Interestingly, high percentage of golden apple shells waste were mismanaged. These had the potential to convert into value-added products such as calcium carbonate (CaCO3). It was found that fresh golden apple shells contained only 24.16±0.48 g/l as CaCO3, while incineration method increased higher CaCO3 products. The result showed that incineration at the temperature of 400 oC gave the highest amount of CaCO3 with the values of 1207.67±9.45 g/l as CaCO3. Based on the resources and the strength of the Ramsar site, the production of value added material from bio-waste could be integrated into waste management strategies along with 3Rs policies implementation.

Collection Programs

Municipal solid waste management has been a topic of interest of several authors over time, in particular the implementation and maintenance of waste collection programmes. Initially, pioneering studies focused on the economic aspects of the provided services. However, many authors later argued the costs of providing solid waste collection services should also be influenced by socio-economic and behavioural factors, exogenous to the municipalities. The present study will be developed in this context, looking, more broadly, to explain the factors influencing the decision-making of the Portuguese municipalities in implementing and maintaining programs of selective collection of solid waste, considering the economic, financial, technological and sociodemographic factors. The results show that, indeed as presented by several authors before, economic factors aren’t the only determinants that influence municipal costs concerning these services, as demographic, geographic and technological factors must be taken into account. Moreover, the enforced legislation also impacts the municipal costs due to municipalities being obliged to contribute to the success of these collection programs in order to fulfil the waste recovery targets. This implies that the costs of these services and the inherent infrastructures are usually financed by its citizens in the form of utilization taxes and also the state.

The main reasons, which this research is based on, are evidenced by the need of technical, political, economic and socioenvironmental coordination for the municipal solid waste management in Brazil and in the State of São Paulo. Most of the counties do not have adequate size to promote the management of MSW, so it’s necessary to perform a consortia to do it. Therefore, it was necessary to characterize the current State of Sao Paulo consortial arrangements considering the environment (including sanitation, waste, water resources, among others). The scale of waste generation and the total population involved in these consortia were also considered. The energy potential of municipal solid waste was evaluated considering two possible technologies: The burning of landfill biogas in engines and the incineration in plants with Rankine cycle. It was identified that the sum of consortia energy potential was 1,454,336 MWh y–1 (landfill biogas), and 2,715,925 MWh y–1 (incineration). It is intended that such results provide significant information and encourage interaction between the different agents involved in the intermunicipal arrangements. It is expected that the characterisation and calculation of energy potential will stimulate future studies about new consortia approaches that consider energy recovery in their projects.

The solid waste management in Brazil is supported by the National Solid Waste Policy (PNRS) and, in the case of municipal waste, the responsibility lies for municipalities. The aim of this research was to describe the perception of the managers of the municipalities of the South Region of Rio Grande do Sul regarding solid waste management. Through the application of a questionnaire addressed to the managers of the cities, difficulties were identified: the lack of technical and financial resources for the implementation of the instruments proposed by the PNRS, such as the Municipal Integrated Solid Waste Management Plans (PMGIRS) and selective collection of municipal solid waste. In addition, there were found problems as the lack of collaboration of the population for the functioning of collection systems and difficulties in the insertion of cooperatives and associations of collectors of recyclable materials within the management cycle. Despite the problems faced, managers recognize the importance of integrated solid waste management to improve management and planning of actions, to promote environmental quality and public health and as a method to reduce costs and raise funds.

This technical report aims to present the construction of a Waste Management System Municipal Solid, held in the city of Cidade Ocidental in Goiás with emphasis on the implementation of a cooperative of waste pickers. To that end, we conducted a literature review containing the context of urban solid waste to Brazil level, the management of municipal solid waste and the guideline for the preparation of a management plan and solid waste management. In primary and secondary sources, diagnostic information was collected performed at the beginning of project implementation, containing municipal information and main points of improvement. It also registered the strategic information for the project implementation, such as management plan for solid waste and actions of the project for implementation of the selective collection system including the incorporation of social technologies and environmental education as a form of awareness to county residents. It was concluded that this report presents a practical way of implementing a management system, enabling alternatives aiming at the implementation of an integrated management system of municipal solid waste that is economical, effective and has social inclusion as premise, especially of people living garbage as an income source. From the selective collection program could be greater integration of collectors in this system, ensuring better working conditions and income.
