Abstract

Municipal sewage sludge can be used as fertilizer as it contains a lot of nutrients. By focusing on copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) contents in municipal sewage sludge from primary oxidation ponds and in plant tissue sections, this study attempts to explain the relationship between plant yield and metal concentrations. Raw sludge samples were collected, air-dried, and ground to powder form at the beginning of fieldwork. The metal concentrations of sewage sludge were copper 6.9 mg/kg; iron 330.2 mg/kg manganese 6.7 mg/kg and zinc 9.1 mg/kg. Orthosiphon stamineus (cat’s whiskers) was selected and the plant received a different quantity of sludge application ranging from 1 g to 4 g per plant weekly for six consecutive weeks while observations were done for eleven weeks. Physical parameters such as shrub width and height were monitored to determine plant growth. Through this study, the determined optimum sewage sludge dosage for cats’ whiskers was between 2 to 3 g per plant.

Abstract

Waste management issue has been a major threat and challenge due to the undergoing rapid industrialization and urbanization not only to Malaysia, but also other countries around the world. To tackle that, the first step starts at household level where people are encouraged to try to manage their wastes properly. The aim of this study was to review the current practises of household waste management, to assess household awareness of the health and safety risked posed by inadequate handling of special household waste and to identify future prospect and potential for effective waste management system in Kampung Parit Haji Siraj, Ayer Hitam, Johor. A survey questionnaire was used to collect complete information on the objectives stated and the data were analysed using SPSS software. Results showed that 97.2% of residents were aware about waste management and social media with 80% contributed the most in delivering information about waste management to the public. The most type of solid waste generated from household were food waste and plastic with 94.4% and 86.1%, respectively. 66.7% of residents emptied their waste container once in 2 days and about 63.9% of the residents dispose their household waste in a hole near their compound. Majority of the residents are aware of any health and safety risked posed by inadequate handling of household waste. Lastly, waste management system in the area can be improved by providing proper waste disposal place and educating proper disposal ways to guarantee that residents do not discard their waste in an indiscriminate manner.

Abstract

Silver nanoparticles (AgNPs) presence has considerable impact on microbial growth. In this paper, AgNPs was deposited on surface of four textiles to enhance the anti-microbial properties using immersion technique. Immersion technique was selected since it was simple, no need high energies, and no additional equipment required. In addition, AgNPs was synthesized using in situ-bio technique which is non-toxic, harmless and eco-friendly approach. Four textiles were evaluated, such as TA, TB, TC and TD. The finding projected that antifungal ability was correlated to the type of the textiles. TC textile has the significant antimicrobial activity with 12.33 ± 2.08 of inhibition zone which followed by TD (16.00 ± 3.46), TB (17.67 ± 7.09), and TA (17.67 ± 6.65). In addition, the surface bonding AgNPs on textile was possibility caused by the -OH group. It has a lone pair of electrons on the O atom that can interact with AgNPs to form –OAg bonds.

Abstract

The issues of global warming and greenhouse gasses have raised the concern of the people and led to integrate ambitious of using bioenergy in many countries. In this paper, the issues of conventional energy are stated, and the different types of conventional energy resources are discussed including coal, petroleum and natural gas. The process of pulverized coal combustion (PCC) to generate electricity is also studied and discussed in this paper to have a better understanding of the process and the emission of greenhouse gas released from the use of coal to generate conventional energy. The reason of soil contamination and air pollution caused by the refinery process of petroleum is also discussed in this paper and several study cases of the social economic impact caused by the production of natural gas in development countries. Furthermore, the used of bioenergy and different type of bioenergy resource are discussed including biogas, algae biofuel, and biodiesel. The process of algae cultivation for algae biofuel and the study of toxic waste algae strains that can give a negative impact to the environment is studied to avoid harmful substances released to the environment. The potential algae application in different fields is also included to show the benefit of algae biofuel which is flexible and able to contribute to the global economic growth. Lastly, the advantages of using bioenergy are discussed including the mitigation of greenhouse gas emission, improve social economic growth, renewable energy resources and prevent prescribed burning of the forest.

Abstract

The adulteration of the environment by hazardous waste, such as heavy metals, nuclear wastes, hydrocarbons, pesticides and greenhouse gases is the major serious problem which need to be reduced. Common remediation technique such as physical, chemical and biological process are being applied. Chemical process can transform and change organic contaminant of interest which is not sufficient to clean the environment, while physical technique requires additional equipment. Thus, bioremediation exist as green approach to eliminate the hazardous waste in the environment. In this review, bioremediation is comprehensively presented. Remediation process types, challenges, limitations, mechanisms, and future suggestion has been elaborated to develop bioremediation technology for future prospect.
