VEGETABLE MARKET (MANDI) WASTEAT APMC, PUNEUTILISATION FOR BIOMETHANATIONPILOT PROJECT (done in 1992) by
S.V.MAPUSKAR*1)Introduction
With a very well established cattle dung based biogas plant programme, it is naturalthat the quest for increasing the biogas generation in the country will lead to developingof biomethanation processes for the use of substrates other than cattle dung. At present,most of them are treated as waste, garbage, nuisance and hazard. The improper or inadequate disposal of such wastes leads to unhealthy conditions. This becomes a sourceof pollution and a public health problem. If such waste is recycled in a biogas plant, itwill be a source of energy, health and wealth.
2)Alternative substrates for biomethanation
When alternative substrates for biomethanation are contemplated, the current cattledung based biogas plant technology will have to be modified to suit the particular alternative substrate. For developing a biomethanation process for each type of substrate,the parameters, the design criteria and the characteristics of the substrate will have to beconsidered as a package for evolving a technology process.
3)Vegetable waste as a substrate for biomethanation
One such alternative substrate for biomethanation is vegetable market waste (Mandiwaste). At present, it’s collection, transportation and disposal is a problem for most citiesand towns where there are vegetable markets. If this waste could be digested in a biogasdigester, both biogas and fertilizer could be produced. In addition, the management of public health problem arising out of such waste could be dealt with effectively. Thereexists a significant potential for processing of such wastes as a new non conventionalenergy source.Ct.—page 2-----------------------------------------------------------------------------------------------------------*Director, Jyotsna Arogya Prabodhan, Dehu Village, Tal- Haveli, Dist-Pune,(Maharashtra) 412 109Secretary, Appa Patwardhan Safai W

    The environmental impacts of farming practices can also be reduced with the adoption of sustainable production methods in the agricultural sector. Growing corn, wheat, rice, and sugarcane produces large amounts of agricultural wastes, some of which are burned, degrading air quality. In the production of cellulosic ethanol, the bulk of the biomass would become a valuable source of energy rather than a waste product. In fact, municipal solid waste (MSW) includes a large volume of cellulosic material that has the potential to be converted to ethanol.…

    Biogas or bio-methane can be used as an alternative source of energy produced through oxygen free (anaerobic) digestion of organic matter in which organic material is processed into a liquid effluent and combustible biogas rich in methane. Generally, biogas contains 55% – 80% methane and 20% - 45% carbon dioxide (CO2). Reliant on the source of organic material and the managing of a anaerobic digestion system, small amount of other gases such as hydrogen sulfide (H2S), ammonia (NH3), and water vapor (H2O) may be created. Specifically, the methane component of the biogas will be fit for producing energy. (1) The methane can be utilized to produce heat, electricity, or both. For example, the methane can be used in in a gas engine to produce electricity, heat the digester, or burned in a conventional gas boiler to produce heat for a nearby apartment complex. (3)…

    Renewable Energy

    • 10 Pages

    In recent decades, there has been an increased need to produce sufficient renewable energy to support global population growth. In response, it has become crucial to find socially responsible sustainable energy resources that offer energy security, reduce greenhouse gas (GHG) emissions, and do not compromise biodiversity or sustainability of existing resources. Despite efforts to reduce the amount of waste produced, a continually growing population limits the space available in landfills. Municipal and industrial waste biomass is often rich in organic matter, allowing for the creation and use of biofuels as an energy source. This organic matter can be used to synthesize ethanol, methanol, and biodiesel through the conversion of inorganic compounds into energy-producing organic carbon compounds. Moreover, unlike fossil fuels, which take millions of years to form, these organic carbon compounds are formed relatively quickly. Biofuel production from waste is beneficial as it allows for better management of landfill sites, and energy production from materials which typically cannot be recycled or composted. Most importantly, it allows for the reduction of significant amounts of methane produced from landfill gas emissions.…

    Secondly, biofuels are more environmentally friendly energy sources when compared to conventional energy sources. As biomass-based energy sources are potentially carbon dioxide neutral and recycle the same carbon atoms in the environment (Demirbas, 2008). That is, the carbon content of the biomass comes from the living organisms, once the carbon content is released into the atmosphere, it will be re-absorbed back by living organism through photosynthesis and hence it forms a carbon cycle with no net release of carbon content to the atmosphere. Moreover, biofuels contain much lower sulphur content than that of petrol and diesel such that the use of biofuel neither leads to air pollution nor global warming.…

    Anaerobic digestion is widely used as a source of renewable energy. The process produces a biogas, consisting of methane and carbon dioxide. This biogas can be used directly as cooking fuel, in combined heat and power gas engines or upgraded to natural gas quality biomethane. The utilisation of biogas as a fuel helps to replace fossil fuels. The nutrient-rich digestate that is also produced can be used as fertilizer.…

    We all have to share this world with its limited resources. We must take advantage of all resources we have, regardless if they came from the earth, are man made, or are waste products. The average person in America throws away 3.7 pounds of garbage every day (Resource Recovery Public Works, 2009). It is no surprise that this leads to landfills that are filling faster than we ever thought due to more people and the increasing throwaway economy. We are facing geological limits for landfills in many areas. Waste-to-energy is a productive method of relieving stresses on natural and man made resources. Waste-to-energy plants turn problems into energy solutions by reducing the amount of garbage and using the energy from the trash as a resource for energy.…

    ABSTRACT Innovations being into management level may take its part as process, product, technology and strategy innovation. A process innovation that meets the energy crisis as well as requirement of effective waste management is proposed in this work. Plastics are inexpensive, lightweight and durable materials, which can readily be moulded into a variety of products that find use in a wide range of applications. As a consequence, the production of plastics has increased markedly over the last 60 years. However, current levels of their usage and disposal generate several environmental problems. Waste plastic disposal and excessive use of fossil fuels have caused environment concerns in the world. Both plastics and petroleum derived fuels are hydrocarbons that contain the elements of carbon and hydrogen. The difference between them is that plastic molecules have longer carbon chains than those in LPG, petrol, and diesel fuels. Therefore, it is possible to convert waste plastic into fuels. The non-catalytic pyrolysis process is the nearest technique to commercialization considering the collection and recycling processes of waste plastics. Unlike incineration or gasification, non-catalytic pyrolysis yield fuel that is almost equivalent to the fractionating column of diesel. The existing use of pyrolysis and the risks involved in it proves that the amount of individual scope was only used for the process of extraction of bio-char for agricultural purpose. But coming to the industry or manufacturing level, the “BIO” concept is altered to meet the future fuel requirements. This process helps the industries to avoid relying heavily on fossil fuels for logistics and other operations.…

    Organic vegetables and fruits are considered important food sources. They are generally inexpensive and though naturally low in fat and calories, they are stillpacked with important nutrients. However, their tendency to spoil easily in their fresh and unpreserved stateresults in organic waste. Organic waste is a type of biodegradable solid waste that comes from plants or animals. Markets that sell organic produce usually generate a high volume of waste from spoiled fruits and vegetables. Like other forms of waste, organic waste must be properly disposed of in order to avoid adverse consequences to the general public’s health and to existing environmental conditions.…

    Open burning of agricultural waste is a common means of disposing crops and wood waste and for clearing land for farming. In rice, the most common way to dispose waste is by in situ burning. Many crops benefit from burning because it is an efficient, effective, and inexpensive method to remove crop residue. It is also an effective means of controlling disease and pest problems. The benefits of rice straw burning include control of the fungal diseases of rice, disposal of rice straw and facilitation of soil tillage and seedbed preparation. It helps to reduce diseases that may occur due to reinfection from inoculum in the straw biomass. Burning is the most labor and cost efficient means of waste disposal. However, the bad effects of such practice had never been studied and analyzed.…
