    Groundwater from fractured granite and metasedimentary rocks in the west coast of Peninsular Malaysia
    (Universiti Pertanian Malaysia Press, 2012) Nasiman Sapari; Raja Zainariah Raja Azie; Hisyam Jusoh
    Hard rock formations consisting of granite and metasedimentary rocks in Peninsular Malaysia, have beenconsidered to be of poor aquifers. The map of shows the area underlain by hard rock as having poorto moderate potential for groundwater production (<230m3/well/day). This paper presents a finding ofproductive hard rock aquifers in the west coast of Peninsular Malaysia. Data from tubewell drillingscarried out for industrial water supply were analyzed.

    Methane gas production from a landfill model under saturated conditions
    (Universiti Pertanian Malaysia Press, 1995) Nasiman Sapari
    A laboratory experiment was conducted to examine methane gas production from landfills under saturated moisture conditions. A landfill model was constructed from a 4-m PVC cylinder of 20 cm internal diameter, to simulate municipal landfill cells of 2.5 m thickness on sandy soils. The same soil was used as the cover material. The landfill was operated over a period of 30 months, for the first 24 months without leachate mobilization and the last 6 months with leachate mobilization.

    Technological and economic evaluation of solid waste scavenging and recycling practices
    (Universiti Pertanian Malaysia Press, 1996) Zainur Dalila Abd Malek; Mohd Nasir Hassan; Nasiman Sapari
    Existing solid waste scavenging and recycling practices in the Klang Valley, Malaysia were investigated through personal visits and field surveys to landfill sites, trading companies and factories involved in recycling. Collection of recyclable material has long been practised in landfill sites as it provides good additional income. Dealers of scrap and recyclable items who operate at the landfill sites provide a source of supply to manufacturing concerns. Glass recycling industries benefit greatly by using recycled cullet, which improves fuel efficiency. Major economic, technical and other constraints related to recycling are discussed.
