SOLID WASTE TREATMENT LABORATORY

I. OVERVIEW

I.1 Introduction

Pollution of solid wastes is a stinging and widespread problem in both urban and rural areas in Vietnam. Increasingly, greater attention is being paid to waste treatment and management.

The  Solid Waste Treatment Laboratory was officially established in 2008 with the establishment of the College of Environment and Natural Resources. The Lab currently devoting to the development of technologies for solid waste treatment and management based on waste quantity, waste characteristics, physical properties and composition. Researches one-waste, plastic waste, bio-waste, sewage sludge and municipal solid wastes are being undertaken.

Laboratory location: The Lab is located in the fifth floor of the Research Laboratory Complex (RLC) building. Room No. RLC 5.16 (solid waste treatment laboratory) and RLC 5.17 (advanced solid waste treatment laboratory). The Lab rooms enable students to gain analytical skills as well as provide a facility for teaching. In addition, postgraduate and undergraduate students, as well as academic staff utilize the room for a wide range of dissertation and research projects.

I.2. Essential functions

Teaching:

The Solid Waste Treatment Laboratory is used predominantly for the extensive practical teaching that goes on at all levels, as well as individual data collection activities for dissertations. We pride ourselves on the high volume of laboratory experience afforded to students in order to reinforce theory covered in lectures and develop students' practical abilities. Accordingly, students consistently comment favourably on the use of laboratory work as part of their learning experience.

The lab is supporting for the following courses:

1.     Waste management and treatment internship

2.     Solid waste and exhaust gas treatment internship

3.     Solid waste and hazardous waste management

4.     Environmental materials

Research:

All lab staff are actively supervising undergraduate and postgraduate students in laboratory research for independent study in the Department of Environmental Engineering. Moreover, our equipments are also serving research activities in other Departments and external users.

Duties:

 The Solid Waste Treatment Laboratory is primarily used by academic staff, undergraduate and postgraduate students. The laboratory is equipped to support the research activity and dissertation projects conducted within the area. In addition, the laboratory is used in the teaching of students involved in the Environmental Engineering and Environmental Management Program.
