    Malaysia has a high rate of depleting forest activities than any other tropical countries in the world. This lead to an increasing of pollution and loss of forest trees include animal to our nature. Lemon grasses as a substitute material from non-wood material had been choose for pulp and papermaking industry. This study was going through the chemical composition analysis and fibre properties for lemon grass pulp. These conclude that lemon grass had a high percentage of cellulose; with a low lignin content; good fibre length by TAPPI method. Thus, lemon grass has a potential to be alternative material for becoming waste-wealth product especially for Malaysia’s pulp and papermaking industry.

    The robust combination of landfill waste recognized as a potential source of hazards. Landfills is one relatively distinctive issue associated with leachate. Generally, zeolite is considered a known adsorbent however relatively very high in cost. Meanwhile, Feldspar is the world’s most common mineral groups which making up as much as about 60 percent of the crust of the earth. Its quality and availability makes the feldspar become relatively low price material. The mixture of feldspar-zeolite are believe to produces effective and inexpensive composite for the treatment of leachate wastewater. The batch experiment was conducted in an Erlenmeyer flask, 250 mL volume with varying the volume of composite mixture ratio and then shaking for 5 hrs with 200 rpm at pH7. The optimum mixing ratio of feldspar-zeolite is chosen 1:1. The optimum removal of COD and ammonical nitrogen is 55% and 50% respectively. The availability of low-cost materials such as feldspar in the composite has helped to minimize the cost of treatment and has helped to increase the potential capacity for adsorption.

    Natural rubber is an important material because of its high strength compared to synthetic rubber. However, the production process of natural rubber discharges a large amount of wastewater containing high concentrations of organic compounds and nitrogen. Therefore, discharging natural rubber processing wastewater without an appropriate treatment can lead to environmental problems such as deterioration of water quality and eutrophication. In this study, the batch adsorption experiment was carried out for the removal of chemical oxygen demand (COD) and ammonia nitrogen from natural rubber wastewater using kaolin as adsorbent. The efficiency of the kaolin was studied by varying the parameters adsorbent dose, pH, shaking speed and contact time. The experimental equilibrium data for this system has been analyzed using the linearized forms of Langmuir and Freundlich isotherms. COD and ammonia nitrogen removal efficiencies were 71.6% and 75.8%, respectively. While, Langmuir isotherm was found to provide the best theoretical correlation of the experimental data.
