Hydrogen sulphide is a poisonous gas that is commonly found in swamps and areas of high volcanic activities. Due to the dangers and hazards that it may impose such as neurological disorders and miscarriages, continuous innovative attempts to remove the gas are in place. A study was conducted to synthesize an adsorbent that is made from activated ri...
Hydrogen sulfide (H2S) is a naturally occurring component found during microbial disintegration and processing of natural gas & oil which can cause wellbeing and condition issue if being discharged into a climate at high fixation. Activated carbon which cost a lot in manufacturing is used as an adsorbent for removing these hazardous gases. As an al...
Food waste (FW) and empty fruit bunches (EFB) possess a great potential to be used for anaerobic digestion process, as these two biomasses are rich in biodegradable organic matter, in which its contents play an important role in determining the efficiency of the digestion process. In this study, the elemental compositions, nutrients content, and li...
Bio-ethanol, a type of biofuel, is known as renewable energy source as it is derived from biomass as its raw material. Biomass can be found in abundance and sustainable i.e. sources are available continuously, unlike the currently used conventional fossil fuels where these sources are limited and depleting. In this study, biomass from fruit waste,...

... The results shown in Table 5 revealed that the values showed significant variation. The production of bioethanol from banana peels using Saccharomyces cerevisiae was reported by Hamzah et al. (2019) to be more efficient at acidic pH values than at alkaline pH values (Table 5). The production rate was dependent on the type of yeast cells used. ...

... Fig. 2 illustrates the closed-loop waste biomass management via anaerobic digestion. Scientists have recently reported that biochar has an incredible potential for contaminants removal from gas and wastewater (Rahman et al., 2019). For example, biochar prepared via carbonization of leaf waste at 400°C removed 84.2 % H 2 S (from 1254 ppm to 201 ppm) from raw biogas for 25 min (Sahota et al., 2018). ...

... EFBs are the remaining parts after oil palm fruitlets are stripped from fresh fruit bunches (FFBs) [4,5]. According to Hamzah et al. [6], the amount of EFB produced is estimated to be 22% of the FFB (in wet weight), which is the largest proportion of oil palm plantation solid waste. Based on the FFB yield data from MPOB (2019) [7], it is estimated that the average total amount of EFB produced from 2017 to 2019 is 22.42 million tons annually. ...
