Detailed Project Report for Municipal Solid Waste Management Collection & Transportation for Nagar Palika Parishad Maharajganj
Chapter 9: System Design and Infrastructure Assessment
T
he objective of any MSW treatment initiative should be to minimize the waste quantity delivered to the processing plant and landfill. Reduce, reuse, recycle and recover concept shall be adopted to reduce the waste generation. The paper, plastics, glass and metals etc. can be reused and recycled. This will enable us to save the valuable resources, while saving energy for equivalent quantity of resources can be extracted from organic portion of waste and used, whereas the inert can be delivered to landfill. The report has brought out the key issues of proper technology selection for MSW for identifying and assessing several treatment technological options available for particular waste composition of the NPP area. The evaluation with the commercial viability and technical feasibility of different alternatives and recommendation of the best suitable option(s) for treatment will increase the efficiency of solid waste disposal system. The focus of the report is to evaluate the present situation of MSW disposal in BNPP area, based on site visits, available data after discussions and information provided by NPP official. An approach to design a sustainable MSW collection and transportation system to meet the future challenges is presented. Various criteria are covered, such as the appropriateness of different collection and transportation options for MSW of NPP, modularity, upgradeability, suitability, regulatory acceptability, reliability and the environmental effects of technology, including cost involved. For designing the primary & secondary collection and transportation of MSW at Maharajganj, the following has been considered. •
NPP comprises of 25 municipal wards covering an area of 27.83 km2, has population of about 1.1 lakhs in 2021 and generates about 26.67 tons of municipal solid waste per day. Current treatment practice involves direct dumping of waste.
•
The qualitative and quantitative assessment for solid waste is carried out at all the major sources of generation. The study was conducted by Consultant, Maharajganj during field visit in July 2021. Quantum of waste generation varies between 239 gm/capita/day. Characterization studies indicate that MSW contains large organic fraction (31.6– 58.9%), metal content (0.28 – 1.02%) and average inert 17.0%, average moisture content is 41.83%, calorific value of refuse ranges between 862.4 – 1090.7 kcal/kg and C/N ratio is between 9:1 to 31:1.
•
Population growth of about 17.86 % per year has been estimated till 2041 for Maharajganj NNP. The solid waste generation in NPP Mrj will also increase in similar way. The estimate shows that population by 2038 would be 6.23 lakhs.
PROPOSED WASTE MANAGEMENT SYSTEM The options analysis has resulted in the identification of a recommended system, the highlights of which are as follows: Primary Waste Collection •
Door-to-door collection service supplemented with community bin services for residential areas;
•
Tricycles/handcart/battery operated tricycle with containers are used for primary collection
•
Auto tipper are generally used for hotels, market areas; and
