The Section of Environmental Engineering Technology undertakes high-quality, high-impact research in a number of areas related to the chemical industry and built environment. We secured significant funding in excess of 1 million Malaysian Ringgit from a wide variety of sources including MoHE’s Fundamental Research Grant Scheme(FRGS), MOSTI’s eScience Fund, MARA’s Skim Gerant Penyelidikan dan Innovasi(SGPIM), UniKL’s Short Term Research Grant (STRG), DAAD RISE Worldwide, governments, industry and professional bodies.

Our research aims to provide new insights into the current technical, social and management challenges facing the environment. Our research outcomes help with informing policy makers and providing the knowledge and tools required by the industries and professionals.

Our research is multi-disciplinary by nature and focuses on three main areas:

Advanced Materials

Biotechnology

Sustainable Development

We have vibrant Master and PhD programs (Research) and also offer Master of Engineering Technology (Green and Energy Efficient Buildings) connected to our research expertise.

Photovoltaic - Battery System to Power Fan-Controlled Rice Husk Gasifier Cooking Stove

The aim of this study therefore was to develop an economical, environmentally friendly, emission-free solution to power the Belonio stove fan. Consequently, a PV-battery system was designed inclusive of charge controller and inverter. The overall efficiency of the PV-battery, battery-inverter, and inverter-fan in the system was found to be 43.8 %. Fan speed had a great effect on inverter efficiency requiring either additional electricity consumers such as lighting or mobile phone charger or the use of a DC fan in which case the inverter can be omitted. However, economically viable fan speed controllers for DC fans must be developed. The daily cost of cooking for an average 5 family household was estimated to be RM 0.40 which can be further reduced with mass production of the stand-alone PV powered Beloniogasifier system.

Dye Removal Using Carbonized Biomass, Isotherm and Kinetic Studies

Effect of thermal treatment on green tea dredge, an abundant waste, for dye removal was investigated in the present study. Variable temperature (800 and 900°C) and residence time in furnace (10 min, 1 and 2 h) were used to prepare six adsorbents which were characterized for surface morphology. The adsorption study was carried out using methylene blue as a model molecule and the effect of shaking time, pH and concentration was determined. Adsorbents prepared at 900°C were found to be more effective than those prepared at 800°C while longer residence time in furnace yielded adsorbents with higher adsorption capacity. The maximum adsorption capacity achieved in this case study was 71.4 ± 4.6 mg/g which is better than many activated carbons derived from other materials. Langmuir model was a better fit in isotherm studies while the sorption process followed pseudo-second-order kinetics.

Treatment and Utilizationof Oil Palm Empty Fruit Bunch (EFB) by Pleurotus Sajor-Caju Cultivation and Vermicomposting

The oil palm industry in Malaysia is striving to show that it uses a sustainable approach in order to be accepted internationally and ensure palm oil remains a major commodity in Malaysia. The Malaysian government has already prohibited the burning of oil palm wastes leaving a problem of waste disposal. In this work, the cultivation of edible mushroom (Pleurotus sajor-caju) on unsterile oil palm waste empty fruit bunch (EFB) followed by vermicomposting by Eisenia fetida and Dendrobaena veneta is investigated as a sustainable approach to dealing with a major component of the waste.
