  • Rubber toughened plastics from thermoplastic waste and rubber waste 
    Wickremaratne, KR; Madusankha, TMS; Premachandra, BAJK [Conference-Extended-Abstract]
    A huge amount of plastic and rubber waste is generated on a daily basis around the world and due to the reason that both rubber and plastic do not degrade naturally and poses a high threat to the environment. Therefore, a ...
  • Effect of urea-based activators on reinforcing activity of silica in natural rubber-based compounds 
    Ambewela, D; Bhashini, JWM; Elvitigala, PSH; Gunapala, O [Conference-Extended-Abstract]
    Silica-filled rubber compounds has a high demand for making white and colored rubber products. Silica-filler has high reinforcing ability compared to other white-fillers. Traditionally, polyethylene glycol (PEG) is used ...
  • Manufacturing of floor tiles using plastic waste and agricultural waste 
    Hussain, H; Perera, H; Premachandra, BAJK [Conference-Extended-Abstract]
    Floor tiles are the most common and widely used construction and building material around the world. Most of the plastic wastes are non-bio degradable and it takes a long time to deteriorate. Even though agricultural wastes ...
  • Manufacturing of roofing tiles by using plastic waste and agricultural waste 
    Wijerathne, DS; Rajamanthree, HL; Premachandra, BAJK [Conference-Extended-Abstract]
    Most available agricultural waste, rice husks and plastic waste, HDPE were selected as raw materials. HDPE is a huge waste material in Sri Lanka. Therefore, it is very important to select HDPE as a raw material for roofing ...
  • Natural paint development using local flora 
    Thuduwage, A; Muthumal, I; Premachandra, BAJK [Conference-Extended-Abstract]
    The objective of this research was to extract the pigments of these waste flowers and use it to produce a natural paint that can be used for frescoes in religious locations as a community service project. The Soxhlet ...
  • Preparation and characterization of natural rubber nanocomposites 
    Guruge, AR; Madubhashana, MKPP; Ranawickrama, LLHSDS; Weerasekara, WMGS; Walpalage, S [Conference-Extended-Abstract]
    Natural rubber nano composite shows good mechanical properties with lower amount of nano clay. This report presents a new strategy for development of natural rubber-clay nano composite with enhanced properties by incorporation ...
  • Property enhancement of natural rubber by blending with rice husk ash and PET powder 
    Ekanayake, EMHL; Hewa, HKLR; Premachandra, BAJK [Conference-Extended-Abstract]
    Rubber industry is a well-established industry with a growing demand in modern world. Rice husk ash and PET (Poly Ethylene Terephthalate) powders are gaining interest as fillers in rubber compounding. RHA filler results ...
