Background • Bangladesh is an agricultural country and poultry is an importantsector. • Now-a-days commercial poultry industry is growing very rapidly. • It provides meat and egg to ensure food security and also generateemployment. Source: Bangladesh Bureau of Statistics(BBS)

Background • PoultryWaste • Poultry waste includes litter, manure, feather, hatchery wastes, entrails and organs of slaughtered birds, processing waste water and blood, dead birds and other debris normally generated in the poultryfarms. • Many farms discharge wastes to our surroundings and nearby water sources. • Lack of poultry processing plant, poultry is slaughtered in open space of market. Generally current poultry waste management situation has negative effects onenvironment

LiteratureReview Relevant Policies
Objectives • Analysis of existing poultry waste management situation in Bangladesh. • Propose scenarios to develop poultry manure recycling plants. • Assessment the socio-economic and environmental benefits of the suggested scenarios. • Development of guidelines/policies for better management of poultry wastes.
Methodology Analysis of current poultry waste management in Bangladesh Secondary information (DLS, BBS, FAOSTAT, Journals) Use of MsExcel Propose scenarios for the development of current situation (using geographic informationsystem) Step1 GIS SuitabilityAnalysis MappingRestriction MappingSuitability Final Suitable Locations for Poultry Waste Development Plants
Step2 ProposedScenarios • Considering these points, this study proposed following 3scenarios: • Energy production from sustainable and relatively environmental friendly source. • Environmental Impactof Synthetic Fertilizers which is reduced by using poultrymanure. • Nutritional demand in fish feed mitigated by poultrymanure. Development of biogasplant Poultry manure is the source of N and rice straw is the source ofC C:NRatio Development of compostingplant For balanced fish feed, proper Carbohydrateand Protein ratio isimportant Development of fish feedplant PM or poultry processing by products are rich source of protein, Rice bran is commonly used for carbohydrate source in Fishfeed. * Rice is the main crop inBangladesh
Step3 Spatial Distribution of Poultry Manure and RiceResidues The detailed data of poultry numbers and yearly rice production are available for Upazilas in the District Statistics,2017. To estimate total available amount of poultry manure, rice straw and rice bran in Bangladesh, the following equations areused: Rp=N.Yp………………..(1) Where, Rp is total manure from poultry, N is number of poultry and Yp is manure (dry matter) generationrate. Ap=Rp.Cp……………….(2) Where, Ap is available poultry manure and Cp is manure collectionfactor. Rc=P.Yc……………………(3) Where, Rc is total residue from each crop, P is annual crop production and Yc is residue to crop yield massratio. Ac= Rc. Cc. Dc.Sc…….(4) Where, Ac is availabe crop residue, Cc is residue collection factor, Dc is residue dryness factor and Sc is surplus availabilityfactor.
