Leaf Litter Vermi Composting: Converting Waste to Resource

Abstract Waste is not waste unless someone wastes it. Solid waste collection and its management is one of the burning issues of environment today in most nations worldwide. Although many methods have been proposed and implemented for proper solid waste disposal but some of these treatment and disposal strategies can cause severe environmental issues. The present manuscript intends to give an overview of studies on use of garden leaf litter waste around us as a substrate for vermicompost formation. Vermicomposting is aerobic process in which detritivorous earthworms play an important role in decomposition of organic waste converting it to nutrient rich medium for plant growth known as vermicompost. They do so by interacting with wide range of microorganisms and variety of other fauna acting as decomposers and this interaction results in stabilization of organic matter leading to alteration of its physical and biochemical properties. In recent years, vermicomposting technique has advanced considerably because it is eco-friendly, economically feasible and socially acceptable approach for waste management. In simple words, it is a way of converting waste to wealth. Furthermore, the end product of vermicomposting (Vermicast) - the nutrient rich compost is an efficient soil conditioner.

Solid Waste Collection

AbstractThe rapid industrial development, high population growth, and rapid urbanization of Saudi Arabia have led to increased pollution and waste levels. Every day, solid waste disposal for governments and local authorities becomes a significant challenge. Saudi Arabia produces over 15 million tonnes of solid waste annually, with a population of around 29 million. The waste production per person is estimated at between 1.5 and 1.8 kg per day per person. About 75% of the population in urban areas is concentrated, making it imperative that government steps are taken to boost the country's waste recycling and management scenario. The production of solid waste in Riyadh, Jeddah, and Dammam, three of the largest cities, exceeds seven million tonnes annually, which shows the enormity of the civic body problem. During this study, the design Expert software was involved in the optimization of process parameters during the collection of municipal solid waste (MSW) from Jeddah city. The use of design experiments and numerical optimization is quite effective in optimizing the different process parameters on the overall cost. Saudi Arabia has a critical need for a resilient waste system and agile waste management system to control its municipal solid waste quickly and environmentally friendly for achieve Saudi Vision 2030. For this study design of experiment, software was employed to optimize the cost per trip, thereby considering process parameters. It is therefore essential to examine the existing practices and future opportunities for solid waste collection, storage, and disposal. This study considered that MSW generated in Saudi Arabia which is having great potential to be converted into wealth. Hence, considering the current environment situation, energy prospective and future management strategies for MSW have also been reviewed.

Background: Solid waste is a by-product of human activities. It has become an alarming challenge during recent decades in many cities of Nepal. Quantity and characteristics of solid waste have changed as a result of the modification in people’s lifestyle. The purpose of this study is to characterize the composition of solid waste in Bhimdatta Municipality of Kanchanpur district, Nepal.Methods: In between July to September 2015, a total of 45 households, 15 commercial places, 15 institutions were selected randomly. Solid waste samples were collected in recommended plastic bags. The collected wastes were categorized and weighted. Direct observation of municipal solid waste collection and its disposal practices were also performed. Qualitative information was collected from focus group discussion.Results: A total of 446.7 kg of solid waste was collected and the highest proportion (66.4%) was organic in composition. In the daily production of overall solid wastes, households were ranked the first (23.3%) and followed to the hotels and lodges (20.4%). The commercial centers produced the highest amount of all types of wastes. The crude waste dumping practice in the open and vacant areas was found a threat to human health, causing ecological imbalances and also bringing land, water, and air pollution.Conclusions: The rapidly growing population in the urban region of the study area has become an urgent issue in the production of several types of solid wastes. The organic waste was generated in the highest amount and maximum proportions of solid waste were produced from commercial centers.

Waste Degradation

Solid waste disposal has become a big concern all over the world. Almost 50% of the municipal waste collected daily, especially in the metropolitan cities where the population is very high, consists of organic solid waste. This organic waste left in the open dumping grounds results in stench and contamination of groundwater. The present study aims to find out the utilization of effective microbial consortia for decomposing the organic waste. Different garbage samples was collected from Panvel area for isolating the effective organic waste degrading organisms. These strains were characterized by microscopic observations and biochemical tests. Their cellulolytic, proteolytic, amylolytic and lipoolytic activities were evaluated. Depending on these enzyme activities, different consortia were prepared and their efficacy in reduction, maturity and deodorization of organic waste was compared. The plant growth promoting effect of this degraded waste on Triticum aestivum (wheat) and Zea mays (maize) was evaluated. 5 Different Microbial Consortium was developed. Microbial consortia increased the efficacy of composting as compared to control. Consortia no. 1 and 5 showed better degrading ability. Consortia 4 and 5 facilitated the best growth for Wheat and Maize respectively. Consortia 2 showed the best result in terms of germination and growth for both wheat and maize

The increasing volume and complexity of waste associated with the modern economy as due to the ranging population, is posing a serious risk to ecosystems and human health. Every year, an estimated 11.2 billion tonnes of solid waste is collected worldwide and decay of the organic proportion of solid waste is contributing about 5 per cent of global greenhouse gas emissions (UNEP). Poor waste management - ranging from non-existing collection systems to ineffective disposal causes air pollution, water and soil contamination. Open and unsanitary landfills contribute to contamination of drinking water and can cause infection and transmit diseases. The dispersal of debris pollutes ecosystems and dangerous substances from waste or garbage puts a strain on the health of urban dwellers and the environment. India, being second most populated country of the world that too with the lesser land area comparatively, faces major environmental challenges associated with waste generation and inadequate waste collection, transport, treatment and disposal. Population explosion, coupled with improved life style of people, results in increased generation of solid wastes in urban as well as rural areas of the country. The challenges and barriers are significant, but so are the opportunities. A priority is to move from reliance on waste dumps that offer no environmental protection, to waste management systems that retain useful resources within the economy [2]. Waste segregation at source and use of specialized waste processing facilities to separate recyclable materials has a key role. Disposal of residual waste after extraction of material resources needs engineered landfill sites and/or investment in waste-to-energy facilities. This study focusses on the minimization of the waste and gives the brief about the various initiations for proper waste management system. Hence moving towards the alternatives is the way to deal with these basic problems. This paper outlines various advances in the area of waste management. It focuses on current practices related to waste management initiatives taken by India. The purpose of this article put a light on various initiatives in the country and locates the scope for improvement in the management of waste which will also clean up the unemployment.
