“…Their effects on soil biological and biochemical properties and plant growth were evaluated in laboratory incubations and a greenhouse trial, using a degraded volcanic soil amended at rates of 20 and 40 g/kg' of vermicompost or compost. Between the two municipal products, the vermicompost had significantly larger nutrient concentrations than the compost when mixed with the soil; the vermicompost also had higher microbial populations size and activity, and produced increased ryegrass yields (Tognettic et al, 2005).…”

Sustainable development (SD) is a concept which first originated in the 1970s when the developed world undertook massive development project in terms of cutting and clearing forests and constructing high rising buildings and spacious highways. Development of a country is essential to meet the needs of its people and to provide people with the latest infrastructure, high rising buildings and recreation facilities. However, the development process concerns the world community as it affects the natural environment. The ecological balance breaks down and environmental degradation occurs at an alarming rate. Therefore, the world community started thinking about protecting the environment while implementing development activities. Environmental degradation also occurs from intensive industrialization of a country. Therefore, to protect the environment, the world community proposed sustainable development. Sustainable development has three components: economic development; social development; and environmental protection. A sustainable development project requires that in any development project, these three components of SD must be taken into consideration and implemented properly so that the environment is not adversely affected. This paper focuses only on a small aspect of environmental protection, that is, proper management of household waste. This paper discusses how household waste in Malaysia can be converted into vermicompost for use in plantations and agriculture. The production of vermicompost may reduce the amount of organic waste in the country and help to maintain a clean and fresh environment. Vermicompost can also reduce emission of methane gas which causes global warming. Descriptive and analytical research methodology has been applied in this research paper. Keywords: Sustainable development, Economic development, Social development, Environmental protection, Vermicompost, Benefits of vermicompost, Global warming, SWPCM Act 2007 1. Introduction Many countries in the world are involved in development. People are industrializing their countries to produce goods to be sold on the local and international markets. They are undertaking massive development projects to build the latest designs of residential and business buildings, to construct spacious highways, tourist resorts etc. Development is needed to enhance the quality of the lives of citizens in a country. Development projects affect the environment, ecology etc. Therefore, for the past few decades people have been talking about sustainable development. There are three components of sustainable development: economic development, social development and environmental protection. The focus of this paper is on environmental protection. There are many factors that contribute to the degradation of environmental quality. One of the factors that contributes seriously to the degradation of environmental quality is household and industrial waste. For example, household waste emits nitric oxide and methane gas that contribute 20% to the greenhouse effe...

“…Generally, after vermicomposting the organic material is ground up to a more uniform size which gives the final substrate a characteristic earthy appearance while the resulting material after composting has normally a more heterogeneous appearance (Ndegwa and Thompson, 2001;Tognetti et al, 2005). The use of compost in horticulture has shown to be occasionally limited by the high electrical conductivity and the excessively high amount of certain ions causing phytotoxicity (García-Gómez et al, 2002) as a consequence of the chemical properties of the initial waste and/or inadequate operation processes.…”

Post transplant success after nursery stage is strongly influenced by plant morphology. Cultural practices strongly shape plant morphology, and substrate choice is one of the most determining factors. Peat is the most often used amendment in commercial potting substrates, involving the exploitation of non-renewable resources and the degradation of highly valuable peatland ecosystems and therefore alternative substrates are required. Here the feasibility of replacing peat by compost or vermicompost for the production of tomato plants in nurseries was investigated through the study of the effect of increasing proportions of these substrates (0%, 10%, 20%, 50%, 75% and 100%) in target plant growth and morphological features, indicators of adequate post-transplant growth and yield. Compost and vermicompost showed to be adequate substrates for tomato plant growth. Total replacement of peat by vermicompost was possible while doses of compost higher than 50% caused plant mortality. Low doses of compost (10 and 20%) and high doses of vermicompost produced significant increases in aerial and root biomass of the tomato plants. In addition these treatments improved significantly plant morphology (higher number of leaves and leaf area, and increased root volume and branching). The use of compost and vermicompost constitute an attractive alternative to the use of peat in plant nurseries due to the environmental benefits involved but also due to the observed improvement in plant quality.Additional key words: peat moss, plant nursery, soil-less substrate, Solanum lycopersicum L. Resumen Compost y vermicompost como componentes de sustratos artificiales de cultivo en viveros: efectos en el crecimiento y morfología del tomateTanto las prácticas de cultivo en los viveros como la elección del tipo de sustrato tienen una gran influencia sobre la morfología de las plántulas y por lo tanto en su adaptación post transplante. Aunque la turba es uno de los sustratos más utilizados en viveros, su uso conlleva la explotación de un recurso no renovable y la degradación de las turberas, por lo que se hace necesaria la búsqueda de sustratos alternativos que puedan reemplazarla total o parcialmente. En este trabajo se investigó la posibilidad de reemplazar la turba por compost o vermicompost en la producción de plántulas de tomate, mediante el estudio de los efectos de proporciones crecientes de estos sustratos (0%, 10%, 20%, 50%, 75% y 100%) en parámetros morfológicos y de crecimiento claves para la adaptación post transplante. Compost y vermicompost mostraron ser sustratos adecuados para el crecimiento de las plántulas. La sustitución total de la turba sólo fue posible con vermicompost mientras que las dosis de compost mayores que el 50% produjeron la mortalidad de las plántulas. Las dosis bajas de compost (10 y 20%) y altas de vermicompost, produjeron incrementos significativos en la biomasa aérea y radicular de las plantas. Además estas dosis mejoraron de forma significativa su morfología (número de hojas, superficie foliar, volume...

“…Atualmente, o enfoque é na integração dos processos de compostagem e vermicompostagem para otimizar a reciclagem (Ndegwa & Thompson, 2001;Singh & Sharma, 2002;Nair & Sekiozoic, 2006;Tognetti et al, 2005). Ambos os processos compõem um sistema tecnológico de baixo custo, para a transformação de resíduos orgânicos em compostos que podem ter alto valor nutricional para as plantas (Hand et al, 1988) e para a produção de mudas (Alves & Passoni, 1997).…”

“…Estudos têm demonstrado que a vermicompostagem, em comparação ao composto produzido sem as minhocas, acelera a estabilização da matéria orgânica e produz um composto com menor relação C/N, maior capacidade de troca catiônica e maior quantidade de substâncias húmicas (Albanell et al, 1988) e fitormonais (Tomati et al, 1995). Além disso, a combinação da compostagem com a vermicompostagem reduz o tempo para obtenção do composto (Ndegwa & Thompson, 2001;Singh & Sharma, 2002).…”

Resumo -O objetivo deste trabalho foi avaliar a produção de adubo orgânico de resíduos domiciliares, por meio da integração de compostagem e vermicompostagem, com e sem esterco bovino nesses processos. Foram realizadas duas etapas experimentais: na primeira, testou-se a termoestabilização dos resíduos e estabeleceram-se condições propícias para a introdução das minhocas; na segunda, aos 27 dias de termoestabilização, os resíduos resultantes da primeira etapa foram colocados em um recipiente de 9 dm 3 , com e sem minhocas, em delineamento inteiramente casualizado, com quatro repetições. Aos 19, 55 e 69 dias, avaliaram-se as taxas de reprodução e sobrevivência das minhocas adultas e os atributos químicos do composto com e sem minhoca. As minhocas sobreviveram e se reproduziram nos substratos, com maior taxa de multiplicação no substrato com esterco. A utilização dos resíduos orgânicos de origem domiciliar, para a produção de insumo, é tecnicamente viável, tanto por meio da compostagem, quanto da vermicompostagem. A adição de esterco não reduziu o tempo de maturação do composto. À exceção do K e Mg, que tiveram seus teores alterados, a integração dos processos de compostagem e vermicompostagem, com e sem esterco, produziu adubos com características químicas similares.Termos para indexação: minhocas, composto orgânico, reprodução. Composting and vermicomposting of home residues with bovine manure for organic amendment productionAbstract -The objective of this work was to evaluate the production of organic amendment from home residues by integration of composting and vermicomposting processes with and without bovine manure. Two experimental steps were adopted: in the first one, thermal stabilization of the residues and adequate conditions were set up for earthworm introduction; in the second step, at 27 days of thermal stabilization, residues remained from the first step were placed in a 9-dm 3 container, with and without earthworms, in a completed randomized experimental design of four replicates. Evaluations were made at 19, 55, 69-day period for reproduction and survival rate of adult worms, and chemical attributes of the compost with and without earthworms. Earthworms survived and reproduced in the substrates, and manure gave the highest reproduction rate. The utilization of organic home residues for production of amendment is technically viable by means of composting or vermicomposting. Addition of doses of manure did not decreased the time for compost maturation. Except for the alteration in the levels of K and Mg, the integration of composting and vermicomposting processes yielded products with similar chemical composition.Index terms: earthworm, organic composting, reproduction. IntroduçãoAs áreas urbanas caracterizam-se pela alta produção de resíduos orgânicos, tanto de origem domiciliar quanto de áreas comerciais e industriais como padarias e açougues, entre outras. Esses resíduos geralmente são aterrados, incinerados a temperaturas acima de 900 o C, ou descartados em terrenos baldios, e constituem-se não s...
