“…Study by authors [31] showed that the number of recycle bins need to be increased to improve the recycle rate among the household in Kuala Lumpur, Malaysia. ReCellular and Rechargeable Battery Recycling Corporation (RBBC) which is a non-profit organisation has established a collective service around the country in Brazil to collect the obsolete cell phones and the results showed that the e-waste recycling rate has successfully increased [36]. Infrastructure also important in encourage the community to foster e-waste recycling behaviour.…”

Abstract. This study aims to identify the set of attributes to facilitate electronic waste (e-waste) behaviour among the community. E-waste disposal is increasing from year to year in parallel with increasing of global population. The short lifespan of electronics and poor e-waste recycling behaviour is among the main contributors to the steadily increasing of e-waste generated. Current recycling rate among the nation is lacking behind, which is only 10.5%. A questionnaire survey has been conducted among the students in Universiti Teknologi Malaysia to evaluate the current e-waste recycling practice. The results showed that majority of the respondents did not recycle their ewaste on campus. Aggressive efforts is needed to realize the country's target of 20% recycling rate in year 2020, one of the effective paths is to minimize e-waste generation via active e-waste recycling behaviour among the community. Extensive literatures have been reviewed to classify the attributes to facilitate effective e-waste recycling among the community. Total of five attributes that identified in this study which are Convenience of Ewaste Recycling Infrastruture and Services, E-waste Recycling Information, Incentives For E-waste Recycling, Reminder to Recycle E-waste And E-waste Recycling Infrastructure and Services. The set of attributes identified in this study may serve as guideline for the management in designing program to foster e-waste recycling behaviour among the community.

“…This indicates that there is degradation of the substrate and the stabilization of compost also occurred. These parameters are within the range required for agricultural use as soil amendment agreed as [24][25][26][27]. The data above showed significant indicator that the product of food waste compost gain from this study is not at an optimum level compare to use of standard compost as fertilizer which is 23: 1 (Kim et al, 2008) [14].…”

High food waste generation in Malaysia that reached up to 15, 000 tonnes per day assign for major problems towards environment, economy and social aspect. Alternative method had been studied for the past years, but composting was seen among the best possible solution to treat this matter. Composting not only has an environmentally method but it also produces a valuable end product that will benefit in agricultural sector. Further studies had been done in this paper to represent their macro and micro nutrient quality as well as their bioavailability towards plant and the analysis of data collected in both CHNS analyser and mathematical method using ultimate analysis. This study also applied enhanced composting process with its segregation, drying, grinding and standard aeration time. Each container has been rotated for 5 minutes yet different resting time was applied which are 25, 55, 155 minutes namely A, B, C and D within 2 hours period. Result shown that overall Carbon (C), Nitrogen (N) and Sulphur (S) concentration increases as the higher aeration was applied while the Hydrogen vice versa. The highest elemental percentage distribution recorded is carbon (31%) while the lowest recorded is S (0.115%). The data collected from Ultimate Analysis was seen not applicable to be use as it has the same content as food waste after composting. The compound molecular formula recorded was C29H7N5S. Regarding ratio of carbon to nitrogen results, it was found that it ranged from 5.39 to 5.71% for different compost treatment under study, where the lowest value of C and N ratio (5.39%) for sample C and the highest value (5.71%) was obtained for sample B with all has the same C/N ratio which is 6: 1 which suitable range in application of soil amendment. Therefore, this study found a significant relationship between chemical factors and compost formation which contribute to better analysis, especially to food waste management.

“…For over the decade, various procedure with preference targets on solid waste management in Malaysia were proposed such as recycling, composting, incineration and others (ordinary dumping) yet low level of accomplishment showed up until today specifically on composting rate is zero to only 1% from the year 2002 to 2006. In the year 2020, the government planned to reduce the landfilling to 50%, by increasing composting to (1) as supported by other study stating biological utilization in degrading organic waste was more proper solution method compared to other treatments such as landfill and incineration in dealing with the organic waste (2). The two largest problems faced by the composting process are odour and leachate where the both of them often correlate with the deficiency of process management.…”

Composting as a method of solid waste management should be given attention. It gives means of producing a valuable end product, by treating of organic wastes in an environmentally friendly method which does not release any hazardous chemical which can affect human health without causing a major disruption to the surrounding ecosystem. Nevertheless, the issue of time-consuming arises and this correspond to the sink of market demand. The optimized pre-composting process was done through drying, grinding and controlled aeration resulted in the fast-compost formation and cost-effective. This study aimed to discover the physical properties of food waste in composting process. The controlled parameter of the composting which is aeration time where pre-composting processes applied was drying and grinding. The manipulated parameter of composting process happened within two durations: rotation and rest. Each container has been rotated for 15 minutes yet different resting time was applied which are 15, 25, 50, 150 minutes namely A, B, C and D. The data collection has been done in hourly basis for the total of 72 hours. Based on the statistical analysis, results show that mass reduction of samples (A=38.6%, B=32.6%, C=24.6%, D=22.6%). The compost temperature ranged between (23°C -39°C) while the compost pH was (5.12 -5.85). Peak level of surrounding temperature was (35.7°C) while surrounding relative humidity (53%) in normal condition. Among the highest moisture content was (52.63%) while the lowest discovered in sample D (24.81%) respectively. Results show that with the longer the aeration time, the better physical properties of compost formed. The obtained data will provide evidence on its significances application to the agencies, the public and the industrial player to cope up with this major environmental threat. This study found a significant relationship between physical factors and compost formation which contribute to better analysis, especially to food waste management.
