Source identification of solid waste in waste water and its potential energy applications

Project Title

Source identification of solid waste in waste water and its potential energy applications

Project Area of Specialization Mechanical EngineeringProject Summary

Solid waste management is one the global challenges today despite many efforts to get rid of this issue [1]. It can be result of continuously increased urbanization and changing life styles. A study shows that world population will reach 9.5 billion by 2050 with more than 66% people in urban areas [2]. Solid waste is found everywhere today including rural and urban areas and water bodies effecting human health, aquatic lives and environment [3]. It consists of different types of waste such as plastic, fabric, textile, paper, rubber, organic waste etc. These are found in different compositions depending upon source, location, life standard of residents, environmental factors and many more [4].  Many of these components can be source of sustainable energy depending upon its abundance. However many studies show today that the most abundant component may be plastic in various forms [5]. Wastewater including commercial, residential, agricultural, hazardous and industrial sources carries the said solid wastes which need to be separated, segregated, quantified, qualified and addressed in terms of its energy potential. Today where solid waste management needs more attention; it is a solution for energy crises too.  Its application as energy source can be the best option to manage this waste for sustainable future.  

Solid waste management and energy crises are global issues today and developing countries suffer too much in this context. Hence sustainable energy generation from solid waste can be the best choice among many workable solutions. Solid waste in wastewater can be a source of energy. Thailand and Pakistan are extensive solid waste producing countries which can be case studies for sustainable energy production. This not only reduces pollution. 

Project Objectives

· To recover and segregate the waste from wastewater

· To convert segregated waste into useful energy

Project Implementation Method

This work is focused on designing the process and fabricating the unit to clean the water and sustainable energy source from distinct types of waste materials from the municipal wastewater. Applications at lab scale from different sample of wastewater the unit will be fabricated from the stainless-steel consistent a pelletizer to convert the pretreated waste into pellets of combustible fuel   and a screen of fiber to trap the solid waste from the water a dryer and controler will be also installed to dry the material for rapid use. controller will control the temperature. we can produce our desire size of pellets.  Many methods for waste management are practiced today all over the world. Reduction, recycle and reuse (3 R’s policy) and integrated solid waste management are the most favorite and effective methods for solid waste management  . Landfill is one of the techniques for municipal and industrial waste management but can be short term solution.  Conversion of waste into energy can be the most attractive solution. Wastewater containing solid waste is taken for study where physical methods are used to remove the solid waste. In case of further metallic and other dissolved waste electro-coagulation can be used where solar cells are used for energy source . Geographical Information System (GIS) will be used for mapping and data interpretation in current study . Solid waste collected during prescribed time period will be washed, dried, segregated and its energy potential will be analyzed. Energy pellets are manufactured using pelletizer and ultimate analysis of fuel pellets will be done accordingly . 

Benefits of the Project

The current statistics for availability of solid waste everywhere show that adverse impacts on human health and its disposal costs are at rising level despite various efforts by local governments, regional organizations and donor agencies. The conversion of this waste to energy is environmental friendly as well as sustainable source. It can also create job opportunities for waste collectors and can be proved as economical source of energy. The use of state of the art GIS mapping for data collection and interpretation not only reduces human inputs but also give more accurate results within short time. It will identify the source, quantify the waste, stop the waste in streets, protects thousands of species and play an important role to resolve the energy crises issue. Besides these outcomes, it has many economic values such as reduced expenses for local authorities, gives a sustainable and cleaner energy and applies long term models which stimulate local economies such as tourism and fisheries. This study is of national as well as of international interest.
