This is a summary of findings from an American Indian rapid cultural assessment. As such, this is not a formal report. The text in this summary of findings has been prepared to fit directly into the Intermodal Environmental Assessment (IM EA). This summary of findings was prepared by a study team of Indian people directly from their own field observations. <p> The American Indian Transportation Committee (AITC) was formed in August of 1996 during a study of American Indian issues related to the transportation of Low-level Radioactive Waste to the Nevada Test Site. The AITC contained 9 members who were selected (with the approval of their respective governments) to represent the 29 tribes involved in the study (see Austin 1998:4). The AITC helped with all aspects of that study, they being deeply involved in developing culturally appropriate research methods, helping with the interviews, and closely reviewing the findings. Their efforts were finally presented in a report entitled Native Americans Respond to the Transportation of Low Level Radioactive Waste To the Nevada Test Site (September 1998) edited by Diane Austin.

Developing countries are facing a great challenge to collect, treat and dispose their waste in a more sustainable way. Today, most of the produced waste ends up on landfills, where they pose a great threat to the environment and human health. Kumasi, the second largest city in Ghana, faces the same issues as other cities in developing countries; waste management is run poorly and most waste ends up on the cities largest landfill, Dompoase, which will be full in a few years time. Issues such as low financial resources, bad urban planning and a growing population aggravate the implementation of a more sustainable development. Since most solid waste in developing countries is organic, composting is a good option towards a more sustainable waste management. There are numerous amounts of articles stating that decentralized composting is the best option for developed countries. Decentralized compost facilities are less costly to install and maintain, they require less technology and decrease the cost of waste transportation. Transportation poses a large expense when it comes  to waste management in developing countries. There is an advantage in integrating a more sustainable waste management in to the existing waste infrastructure since cities often are densely built up and there is a shortage of land. Therefore this thesis has investigated the possibilities of having waste sorting stations and decentralized compost facilities at public dumping sites in the Bantama area, one of ten sub--‐metros in Kumasi. Based on literature and observations during field visits in the Bantama area, a classification scheme was developed. The classification scheme was designed to simplify identification and differentiation of the sites. It contains thirteen criteria to consider when planning for organic waste sorting stations and decentralized compost facilities. Suitable sites for sorting stations and decentralized compost facilities were selected by a SQL analyzes in a Geographic Information System (GIS). The analyzes was based on the classification scheme. The result shows that of twenty--‐one public dumpingsites, seven were suitable as sorting stations and two sites were suitable for a decentralized compost facility. The expectation is that in due time and with infrastructure improvements, more than only seven communal sites can become sorting stations. When it comes to sites for composting the result reveals an issue in many cities  there is just not enough land to build as many decentralized facilities as would be necessary to recycle all organic waste. However, due to the advantages of having decentralized facilities, the recommendation is that Kumasi should start with a decentralized approach and as finance and technological skills exists the organic waste management can extend to also include larger facilities. Further this thesis shows the advantage of having decentralized composting when it comes totransportation costs. A transport analyzes was done in a GIS,  which showed the difference intransportation distances between having decentralized and centralized composting. The result showed that waste recycled close to its source, i.e. having decentralized waste management, is transported shorter distance compared to having centralized composting and  thus saving on cost for transportation.

The transportation phase of solid waste management is highly critical as it may constitute approximately 60 to 75 percent of the total cost. Therefore, even a small amount of improvement in the collection operation can result in a significant saving in the overall cost. Despite the fact that there exist a considerable amount of studies on Vehicle Routing Problem (VRP), a vast majority of the existing studies are not integrated with GIS and hence they do not consider the path constraints of real road networks for waste collection such as one-way roads and U-Turns. This study involves the development of computer software that optimizes the waste collection routes for solid waste transportation considering the path constraints and road gradients. In this study, two different routing models are proposed. The aim of the first model is to minimize the total distance travelled whereas that of the second model is to minimize the total fuel consumption that depends on the loading conditions of the truck and the road gradient. A comparison is made between these two approaches. It is expected that the two approaches generate routes having different characteristics. The obtained results are satisfactory. The distance optimization model generates routes that are shorter in length whereas the fuel consumption optimization model generates routes that are slightly higher in length but provides waste collection on steeply inclined roads with lower truck load. The resultant routes are demonstrated on a 3D terrain view.

Sendo assim, este trabalho tem como objetivo avaliar a eficiência dos serviços de coleta e transporte de resíduos sólidos domiciliares e comerciais em centros urbanos a partir da otimização de rotas, tomando como base de estudo, os bairros Liberdade e Jeremias. A metodologia deste estudo consiste em utilizar técnicas matemáticas por meio de um algoritmo que é integrado a um software roteirizador, que define a melhor rota, segundo a variável que se quer otimizar; sendo utilizadas nesta pesquisa as variáveis distância, tempo de viagem, topografia e intensidade de tráfego de veículos. Os resultados encontrados reforçam a ideia de que a rota atual de coleta de resíduos necessita de melhor planejamento e de melhorias e que as variáveis da topografia são um aspecto importante a ser considerado. Com a adoção das rotas otimizadas, em detrimento da rota atual de coleta, a empresa responsável pela prestação do serviço poderia ser mais eficiente, realizando a mesma atividade em menor tempo e ainda economizar recursos necessários para a prestação do serviço. Desta forma, com a aplicação dos resultados na prática, a empresa poderia economizar, anualmente, mais de R$ 15.000,00, apenas utilizando as rotas otimizadas para os dois bairros avaliados. Ao expandir esta análise para toda a cidade, os resultados podem chegar a elevadas reduções de custos anuais e tais economias financeiras podem ser redirecionadas para a melhoria do próprio sistema de gerenciamento de resíduos sólidos da cidade, inclusive voltado às ações de coleta seletiva, que ainda é tão incipiente em Campina Grande. / The disorderly growth of Brazilian cities, associated with the lack of implementation of policies and the lack of planning in the provision of basic sanitation services in municipalities, the sustainability of a quality collection and transportation service is a municipal management service. The objective of this work is to evaluate the efficiency of solid and commercial solid waste collection and transportation services in urban centers, based on the optimization of routes, based on the study of Liberdade and Jeremias neighborhoods. The methodology of this study consists in using mathematical techniques by means of an algorithm that is integrated in a routing software, which defines a better route, according to the variable to be optimized; Being used in the research as variables of speed, travel time, topography and traffic intensity of vehicles. The results reflect an idea that the current rotation of waste collection needs better planning and improvements and that topography variables are an important aspect to be considered. With the adoption of optimized routes, in detriment of the current route of collection, a company responsible for providing the service could be more efficient, performing the same activity in a shorter time and still save the resources needed for a service rendering. In this way, with an application of the results in practice, a company could save annually more than R $ 15,000.00, only using as optimized routes for the two evaluated neighborhoods. By expanding this city-wide analysis, results are available at high annual cost reductions, and such financial savings can be redirected to an improvement in the city's own solid waste management system, including targeted selective collection actions, which It's so incipient in Campina Grande.

Orientadora: Profª Drª Silvana Zioni / Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Planejamento e Gestão do Território, 2015. / A Lei nº 12.305 de 2010, que sancionou a Política Nacional de Resíduos Sólidos (PNRS), estabelece novos paradigmas à gestão de resíduos sólidos (RS) no Brasil. Estes, somados à situação atual de grande geração de RS e suas consequências, levantam questionamentos quanto aos processos e etapas do gerenciamento dos RS, como a coleta e o transporte dos resíduos sólidos urbanos (RSU), que representam a parcela mais onerosa do serviço de limpeza urbana e manejo dos RS, e que geram impacto ambiental e social consideráveis. A hipótese que aqui se estabelece é que este serviço não é considerado pelas políticas de gestão de RS brasileiras. Esta pesquisa investiga, especificamente, como o transporte dos RSU é abordado nas políticas sobre gestão de RS, principalmente na escala local, que é a mais afetada por esta etapa do processo, através de uma análise da PNRS, do Plano Nacional de RS e dos Planos Municipais de Gestão Integrada de Resíduos Sólidos (PMGIRS) dos Municípios do Grande ABC, Região Metropolitana de São Paulo. Para estabelecer uma base reflexiva a ser aplicada nesta análise, foram constituídas categorias analíticas a partir das diretivas de RS portuguesas e da abordagem destas sobre a problemática do transporte dos RS. Constatou-se que as diretivas brasileiras, mesmo as locais, citam o transporte apenas como uma etapa do gerenciamento dos RS, não abordando a importância deste processo, ou o impacto causado por ele, sem preocuparem-se em regulá-lo. / The Law No. 12.305 of 2010, which sanctioned the National Policy on Solid Waste establishes new paradigms for solid waste (SW) management in Brazil. These, added to the current situation of great generation of SW and its consequences, raise questions about the processes and stages of management of the SW, as the collection and transportation of municipal solid waste (MSW), which represents the most costly portion of service urban sanitation and management of SW, and generates significant social and environmental impact. The hypothesis here established is that this service is not considered by Brazilian solid waste management policies. This research examines specifically how the transport of MSW is approached in public policies on the SW management, especially in the local level, which is the most affected by this process step, through an analysis of the National Policy and Plan of solid waste and Municipal plans for management of solid waste of the Grande ABC municipalities, metropolitan region of São Paulo. To establish a reflective base to be applied, analytical categories were constituted from the Portuguese SW policies and their approach of the problem of transport of SW. It came into sight that Brazil's policies, even local, cite transportation as just a step in the management of SW, not addressing the importance of this process, or the impact caused by it, without thereby be concerned in regulating it.
