Decentralized management of organic household wastes in the Kathmandu Valley using small-scale composting reactors

The sustainable management of municipal solid waste in the Kathmandu Valley has always been a challenging task. Solid waste generation has gone rapidly high in the Kathmandu Valley over the last decade due to booming population and rapid urbaniza-tion. Finding appropriate landfill sites for the disposal of solid wastes generated from the households of the Kathmandu Valley has always been a major problem for Nepalese government. 65 % of total generated wastes from the households of Nepal consist of organic materials. As large fractions of generated household wastes are organic in na-ture, composting can be considered as one of the best sustainable ways to recycle organ-ic wastes generated from the households of Nepal. Model Community Society Development (MCDS), a non-governmental organization of Nepal carried out its small-scale project in five households of the Kathmandu Valley by installing composting reactors. This thesis is based on this small-scale project and has used secondary data provided by MCDS Nepal for carrying out the study. Proper man-agement of organic wastes can be done at household levels through the use of compost-ing reactors. The end product compost can be used as soil conditioners for agricultural purposes such as organic farming, roof-top farming and gardening. The overall average organic waste generation in the Kathmandu Valley is found to be 0,23 kg/person/day and the total amount of organic household wastes generated in the Kathmandu Valley is around 210 Gg/yr. Produced composts from five composting reac-tors contain high amount of moistures but have sufficient amount of nutrients required for the fertility of land and plant growth. Installation of five composting reactors in five households have prevented 2,74 Mg of organic wastes going into the landfills, thus re-ducing 107 kg of methane emissions which is equivalent to 2,7 Mg of carbondioxide.

O valor da elaboração de relatórios de sustentabilidade para as empresas de mineração

Sustainability has been moving up on the business agenda in recent decades, and many methods to assess corporate sustainability have already been created. One of the most used and reliable methods is the Sustainability Reporting Guidelines of the Global Reporting Initiative (GRI). Given the importance of sustainability for society and organizations, this study examined sustainability reports published by mining companies – Alcoa, Vale and Samarco – since 2006. The objective was to verify the indicators that contribute most to the minimization of environmental impacts and the improvement of environmental performance. The methodology consisted of collecting and analyzing data from the GRI sustainability reports. It was discovered that the sustainability reports helped the companies to identify improvement opportunities and it is essential companies provide in their reports an economic, environmental and social context of their activities. Furthermore, it was found out that the indicators related to atmospheric emissions, solid waste generation, environmental protection expenditure, and the consumption of raw materials, energy and water are the ones more attached to the production process, which means they are the main contributors for the environmental performance improvement

A geração de resíduos sólidos urbanos e sua influência na gestão urbano-ambiental municipal de Sorocaba/SP

In Brazil, rates of urban solid waste generation increase proportionally more than the annual growing of the population. The government, from its federal authority to the municipal spheres, faces increasing challenges for Urban and Environmental management regarding to solid waste in general and, in particular, municipal solid waste. Financial problems added to public health problems that worsen with the serious environmental impacts generated every year. In August 2010 Brazil the PNRS (National Policy on Solid Waste) was approved and sanctioned in which represented a true watershed in the country as a legal framework extremely ambitious and visionary. This work presents the successes and challenges that the municipality of Sorocaba/SP is facing after more than three years of PNRS sanctioned to conduct an Urban and Environmental management suited to the new legal bases towards the subject of solid waste. The results show a large gap between the content proposed by the law and the technical, financial and temporal reality to practical implementation by the municipal government. New legislation and federal incentives, consortiums among the cities, flexible deadlines and environmental education at all levels are certainly some proposals to catalyze processes that aim to solve and overcome the challenges of solid waste

Gestão ambiental na produção avícola: estudo de caso

The present study addresses the application of the Environmental Management System in chicken production on a farm owned by the Nardo brothers, located in the city of Guapiaçu/SP (Brazil). The objectives were to analyze the process of solid waste generation, destination and forms of treatment in this activity; propose measures to reduce the use of potable water for non-potable ends; determine other measures identified through a questionnaire drafted by Embrapa (Brazilian Agriculture Research Cooperative) and administered to employees who have direct involvement in the productive process; pay visits to chicken production enterprises; and employ the guidelines proposed by the National Fowl-Breeding Sanitation Program that guide the application of the Environmental Management System. Adequate management of waste was put into effect through the construction of a compost shed capable of meeting current production demands, in which all procedures were accompanied – from civil construction to the commercialization process of the organic fertilizer generated. The rain-gathering system for the roofs of the pens proposed to reduce the consumption of potable ground water destined for washing the floors of the pens was completely dimensioned and budgeted, allowing the motivated owners to place the project into effect in a timely fashion. Other simpler but no less important proposals were also made in order to bring the production up to the required quality standards.

A política nacional de resíduos sólidos e o plano diretor municipal de Rio Claro/SP: o uso como instrumento para a gestão urbano-ambiental municipal

Due to the large economic development associated with the growing consumerist lifestyle of our capitalist society, the problem of uncontrolled solid waste generation worsens, which one is considered to be one of the main responsible factors for environmental degradation. As a case study and in order to solve the problem of large generation of municipal solid waste, this work aims to study the “plano diretor” of Rio Claro city, São Paulo. The “plano diretor” is a municipal law that provides guidelines for the administration of the city, which include guidelines for the management of solid waste generated in the city. The guidelines required in order to write the “plano diretor” are provided by the national law “estatuto da cidade”, providing information for the planning and development of the cities, as well as the management of the urban environment. However, only the “estatuto da cidade” does not provide enough instructions for creating management plans in order to solve the many problems from the urban environment. Thus, studies have been done about urban and environmental management, to understand how municipal management plans should be structured. As a form of seeking information that can complement the “plano diretor” to the creation of policies for managing solid waste of the city, the “Política Nacional de Resíduos Sólidos”(PNRS) emerges in 2010 as a document which provides principles, objectives and guidelines to create plans for Solid Waste Management at the national, state, regional and municipal levels. Therefore, it was possible to make a joint analysis of the “plano diretor” of Rio Claro with the PNRS to identify what is already done within the municipality about the solid waste management, and identify which aspects are most significant in the municipal solid waste management that the national policy provides. Yet studies have been done on the current municipal solid waste management...

Examining the Justification for Residential Recycling

Municipalities in the United States have for the past two decades initiated two policies to reduce residential solid waste generation by increasing recycling. The first policy, implemented in over 4,000 municipalities in the United States, requires households to pay a fee for each unit of garbage presented at the curb for collection. The second policy, initiated in 8,875 municipalities, subsidizes household recycling efforts by providing free curbside collection of certain recyclable materials. Both initiatives serve as examples of incentive-based environmental policies favored by many economists. But before economists can celebrate this wide-spread adoption of incentive-based environmental policies, further examination reveals that potentially inefficient command and control policies have been more instrumental in promoting recycling than might be commonly known. This article examines the empirical lessons gained from studying twenty years of solid waste policy in the United States and argues for the replacement of several state recycling mandates with a system of state and/or national landfill taxes.

Compostos fenólicos de resíduos agroindustriais: identificação, propriedades biológicas e aplicação em matriz alimentar de base lipídica

A geração de resíduos sólidos pelas atividades agroindustriais tem criado a demanda por um reaproveitamento tecnológico desses materiais. Assim, o objetivo deste trabalho foi avaliar o potencial bioativo e tecnológico de resíduos agroindustriais, como fontes naturais de compostos fenólicos com atividade antioxidante. Foram analisados resíduos agroindustriais vinícolas, de indústrias produtoras de polpas congeladas de frutas (açaí, cajá, cupuaçu e graviola) e provenientes do beneficiamento de café e de laranja. Inicialmente, foi realizado um estudo para a determinação das condições ótimas de extração, empregando planejamento experimental multivariado com delineamento composto central rotacional, cujos resultados foram avaliados empregando a técnica de superfície de resposta. Na sequência, foram feitos a triagem dos resíduos, baseada na atividade antioxidante, e a caracterização fenólica dos extratos hidroalcoólicos obtidos dos resíduos agroindustriais. De acordo com os resultados de atividade antioxidante, engaço de uva da variedade Chenin Blanc (EC) e semente de açaí (SA) foram os resíduos selecionados, os quais seguiram para as etapas de concentração e fracionamento bioguiado de sua(s) molécula(s) bioativa(s), as quais foram posteriormente identificadas por UHPLC-ESI-LTQ-MS. Extratos brutos e concentrados foram avaliados in vitro quanto à capacidade de desativação de espécies reativas de oxigênio (radicais peroxila, ânion superóxido e ácido hipocloroso) e então, aplicados em óleo de soja, emulsão e suspensão de lipossomos, a fim de se avaliar a efetividade desses extratos como antioxidante natural em matrizes lipídicas. Concentrações intermediárias de etanol (40-60%) e alta temperatura (96°C), exceto para semente de açaí (25°C), foram as condições ótimas para a extração de antioxidantes dos resíduos agroindustriais. Epicatequina, ácido gálico, catequina e procianidina B1 foram os compostos de maior ocorrência, quando avaliados pela técnica de HPLC-DAD. O EC apresentou a maior atividade antioxidante global e SA a maior atividade entre os resíduos de polpas de frutas, laranja e café. A concentração dos extratos brutos de EC e SA, pela resina Amberlite XAD®-2, produziu aumento significativo da atividade antioxidante. Além disso, extratos brutos e concentrados apresentaram atividade antiproliferativa e anti-inflamatória. Os extratos concentrados foram fracionados por meio de Sephadex LH-20, a partir da qual foi possível identificar quatro frações de maior bioatividade para o EC e três para o SA. Procianidina B1, catequina, epicatequina e resveratrol foram identificados no extrato concentrado e frações de EC. Dezoito procianidinas poliméricas, catequina, epicatequina foram os principais compostos identificados em SA, por meio de UHPLC-ESI-LTQ-MS. Resveratrol também foi encontrado em SA pela primeira vez. Quando avaliados em óleo de soja, EC e SA demonstraram atividade pro-oxidante. Contudo, elevada atividade antioxidante foi verificada quando essas amostras foram aplicadas em sistemas lipídicos coloidais, pois retardaram o consumo de oxigênio em uma emulsão óleo/água e o período de indução na produção de dienos conjugados em uma suspensão de lipossomos. Portanto, os resíduos agroindustriais EC e SA possuem potencial tecnológico de reaproveitamento industrial podendo ser considerados possíveis matérias-primas para a obtenção de extratos ricos em antioxidantes ou pela extração de antioxidantes naturais de uso pelas indústrias farmacêutica e/ou de alimentos.

Integration of Sustainable Development Principles into a Community Park

Characteristics of six operating hot spring recreational facilities were reviewed to identify opportunities for integrating a range of sustainable design and operation approaches into a community park. Potential operating cost savings were evaluated for a conceptual landscape project, bathhouse project, and swimming pool project that reduced the use of electricity, natural gas, water, the discharge of water, and solid waste generation. The projects showed a combined cost savings of approximately $40,000 per year by adopting passive solar design, energy efficient lighting, native vegetation, water efficient fixtures, and a natural swimming pool. The greatest potential operating cost reductions were observed for cutbacks in the use of swimming pool water and reductions in natural gas needed for building and swimming pool heating.

Gestão de resíduos sólidos domiciliares na cidade de Chibuto, província de Gaza Moçambique

This study analyzes the process of generation and management of solid waste in the Municipality of the City of Chibuto-Mozambique, drawing on the different approaches towards allocation and the socio-environmental implications resulting from this process and waste spatial distribution. To answer these objectives a questionnaire was administered to 367 households distributed in 14 neighborhoods of the city to elicit information on how solid waste is treated and what could be its impact on public health of the residents. From this perspective, the questionnaire gasp information from immigrant residents regarding both their origin, and socio economic condition. Apart from the questionnaire, semi-structured interviews were conducted to staff working on the Sanitation Sector, Urbanization Sector of the Chibuto Municipality, including the Health Service, and Women and Social Affairs. In addition to these data collection methods, for further discussion on the subject, the researcher draw a theoretical framework grounded through literature review, as well as systematic observation of the phenomenon. Research findings revealed that the solid waste collection services provided by the Chibuto Municipality do not follow the procedures laid down in the Regulation on Solid Waste Management, which advocates environmentally safe, sustainable, and complete management of waste. First, the services use open dumps for waste management. Secondly, waste collection does not cover all citizens living in the neighborhoods governed by the municipality, due to financial, technical, and organizational reasons. More importantly, the study found that due to this failure, more than 90% of households surveyed continue to use the traditional methods on waste management which include burning, or the burial techniques. On the other hand, some citizens throw waste on the streets, a method that threatens public health because it increases cases of diseases related to sanitation problems such as (diarrhea and malaria), especially in suburban and peripheral urban areas. Concerning with the above mentioned problems which constitute a real threat to the public health, some ways are proposed for more sustainable and spatially appropriate solid waste management through recycling, waste sorting, composting, reuse, and reduction of solid waste generation.
