Abstract: The purpose of this study is to assess the current state of waste management in the Yen Bai City, Yen BaiProvince, in order to offer appropriate solutions to improve management efficiency This study analyzes the issues related to domestic solid waste in Yen Bai City such as the characteristics of solid waste, solid waste generation, status of collection, classify, transportation and treatment and reuse of domestic solid waste Yen Bai City is the political and economic and cultural center of Yen Bai Province is the most densely populated place in the province The status of domestic waste management is still inefficient which leads to overlapping of an Lu management systems and lack of synchronous investment In addition, the sense of n va environmental protection among people is still not good ac th Therefore, to effectively the management of domestic solid waste in Yen Bai City, appropriate solutions and management strategies should be planned and d si implemented

PART I INTRODUCTION 1.1 Rationale of the study Yen Bai city is the political center of Yen Bai province It can be concluded that the province has reached its maximum economic growth in the past years through the development of various sectors However, the current status of general waste and domestic waste in particular have not been fully evaluated and audited, provided that this leads to difficulty in collection and waste management No appropriate measures on proper disposal has been done Therefore, the assessment of the current status of the management and treatment of household waste is one of the vital problems of Yen Bai city The purpose of this research is to have an access to the situation of Domestic Solid Waste (DSW) management system in Yen Bai City The study will mainly focus on the advantages and disadvantages in waste management in order to find the rational management solutions for domestic solid waste management system in Yen Bai City an Lu From there, we can improve the effect in solid waste management and reduce the n va pollution because of the irrational collection, transport and treatment system ac th 1.2 Objectives of the study d si d oa waste in

third-class city, with the natural area is 106.74 km2, the population is 97,907 The social and economic conditions of the city have progressed over the years On another hand, this development also triggered increasing domestic waste, and the danger of environmental pollution Yen Bai City is the mountainous urban, the terrain is divided by mountains Furthermore, people often put the domestic waste together with the straw, sticks, making difficult to the management and process of domestic waste collection in the city The sanitation teams cannot collect thoroughly the domestic waste in the areas At present, the volume of waste generated in Yen Bai City are about 70-80 tons/day and about 27 375 tons/year The amount of garbage generated from various an Lu sources such as: households, markets, offices in which the source of generated n va primarily from household take up 62.07% of the total; the percentage of waste from ac th markets and offices are 15.71% and 19.28% in turn, and 2.94% is from others d si The nl ow Composition of domestic solid waste in Yen Bai city is very diversified d oa percentage of organic waste is highest with 62% of the total This kind of waste is oi
