Electrical and electronic waste condition and handling practices in bangi Industrial Estate, Selangor
Author(s)-  Nur Fatihah Roslim, Mohd Bakri Ishak

ABSTRACT

Due to the swift replacement of aged model by latest advanced model time to time causes short average lifespan of electrical and electronic equipment (EEE) and therefore leads to yield mass generation of waste electrical and electronic equipment (WEEE). EEE contains different hazardous materials which are harmful to human health and the environment if do not disposed carefully but E-waste is a valuable source for secondary raw materials once treated it properly. Safely recycling and discarding obsolete electronics can promote the safe management of hazardous components and supports the recovery and reuse of valuable materials. The reason is also due to the fact that the facilities are insufficiently designed to handle such kind of wastes. In addition, Malaysia is a developing country and there are many industrial areas in this country, for example Bangi Industrial Estate. Industrial area is one of a major producer of E-waste. This research seeks to study the current handling practices of WEEE in Bangi Industrial Estate, Selangor. In this research, observation, inspection and interview about E-waste handling practices was carried out in study area.

Bridging the Gaps:  An E-waste management and recycling assessment of material recycling facilities in Selangor and Penang
Author(s)- John Babington C, Chamhuri Siwar, Ahmad Fariz  M, Rawshan Ara B

ABSTRACT

The uses of electronic and electrical devices have relatively increased with rapid increases in economic and technological development over some period of time in Malaysia. There is needs for Malaysia to apply “3R” principles of reduce, reuse and recycle for efficient control and management of material circle of electronic and electrical equipments (EEE). This paper tends to highlight, the e-waste recycling practice within the material recovery facilities (MRF) studied in Selangor and Penang, the guidelines overseeing the e-waste recycling activities, stakeholders and future plans for e-waste management in Malaysia. A total of 25 questionnaires were sent to MRF through email, fax and personal delivery and a questionnaire with personal discussion held with the department of environment (DOE) Malaysia. The result shows that e-waste recycling in Malaysia is still at infancy as there are no sophisticated technologies to carry out complete recycling process in a MRF, lack of specific regulation on e-waste, poor e-waste collection from households at the same time help us to understand various activities going on within the MRF studied. The findings from this study will help the waste management authorities in bridging the gaps that militate against proper e-waste management in Malaysia.

Studies on Concrete containing E plastic waste
Author(s)- Lakshmi.R, Nagan.S

ABSTRACT

Utilization of waste materials and by-products is a partial solution to environmental and ecological problems. Use of these materials not only helps in getting them utilized in cement, concrete and other construction materials, it helps in reducing the cost of cement and concrete manufacturing, but also has numerous indirect benefits such as reduction in land-fill cost, saving in energy, and protecting the environment from possible pollution effects. Electronic waste, abbreviated as e-waste, consists of discarded old computers, TVs, refrigerators, radios – basically any electrical or electronic appliance that has reached its end-of-life.  Efforts have been made in the concrete industry to use non biodegradable components of E waste as a partial replacement of the coarse or fine aggregates. An experimental study is made on the utilization of  E-waste particles as coarse aggregates in concrete with a percentage replacement ranging from 0 % to 30% on the strength criteria of M20 Concrete. Compressive strength, Tensile strength  and Flexural strength of Concrete with and without E-waste as aggregates was observed which exhibits a good strength gain. Ultrasonic tests on strength properties were executed and the feasibility of utilizing E plastic particles as  partial replacement of coarse aggregate has been presented.
