Increase in the energy usage and declining of non-renewable fossil fuels has changed the perceptions to energy recovery methods to satisfy the need of the energy. Through extensive research and innovation of technology, especially to recover the plastic waste to energy feedstock has been developed. The chosen plastic waste samples are polyethylene terephthalate (PET), high-density polyethylene (HDPE), and polypropylene (PP). This sample is collected from daily household waste and was characterized according to the resin types or plastic types. In this research the determination of the moisture content and ash analysis has been carried out using proximate analysis and also determination of the carbon, hydrogen, nitrogen, and sulphur content has been carried out by using the ultimate analysis. In addition, the calorific value of the samples has been determined and activation energy is obtained based on thermogravimetric analysis (TGA) data. The chosen kinetic modelling is modified Arrhenius equation. According to the results, HDPE was the best choice for energy recovery from waste plastics in Malaysia due to high calorific value, low activation energy, low moisture content and ash content and it has low sulphur content among all the plastic samples experimented.

Continuous Demand

Wastes from landfills originate from many spheres of life. These are produces as a result of human activities either domestically or industrially. The global plastic production increased over years due to the vast applications of plastics in many sectors. The continuous demand of plastics caused the plastic wastes accumulation in the landfill consumed a lot of spaces that contributed to the environmental. In addition, economic growth and development also increased our demand and dependency on plastics which leads to its accumulation in landfills imposing risk on human health, animals and cause environmental pollution problems such as ground water contamination, sanitary related issues, etc. The management and disposal of plastic waste have become a major concern, especially in developing cities. The idea of waste to energy recovery is one of the promising techniques used for managing the waste of plastic. Hence, this paper aims review at utilizing of plastic as an alternative fuel.

Land Filling

The disposal of waste plastics has become a major worldwide environmental problem. The USA, Europe and Japan generate annually about 50 million tons of post-consumer plastic waste, previously landfilled, generally considered as a non-sustainable and environmentally questionable option. Landfill sites and their capacity are, moreover, decreasing rapidly, and legislation is stringent. Several European Directives and US legislation concern plastic wastes and the required management. They are briefly discussed in this paper. New processes have emerged, i.e., advanced mechanical recycling of plastic waste as virgin or second grade plastic feedstock, and thermal treatments to recycle the waste as virgin monomer, as synthetic fuel gas, or as heat source (incineration with energy recovery). These processes avoid land filling, where the non-biodegradable plastics remain a lasting environmental burden. The paper reviews these alternative options through mostly thermal processing (pyrolysis, gasification and waste-to-energy). Additional research is, however, still needed to confirm the potential on pilot and commercial scale.

Waste Plastic Oil

The demand for plastic is eternally growing in urban areas and producing enormous quantity of plastic waste. The management and disposal of plastic waste have become a major concern worldwide. The awareness of waste to energy retrieval is one of the promising modes used for the treatment of the waste plastic. The present investigation evaluates the prospective use of waste plastic oil (WPO) as an alternative fuel for diesel engine. Different blends (WPO0, WPO30, and WPO50) with diesel are prepared on a volume basis and the engine is operated. Experiments are conducted for various injection timings (9 deg, 12 deg, 15 deg, and 18 deg BTDC) and for different exhaust gas recirculation (EGR) rates (0%, 10%, 15%, and 20%) at 100 MPa injection pressure. Combustion, performance, and tail pipe emissions of common rail direct injection (CRDI) engine are studied. The NOx, CO, and Soot emissions for waste plastic oil-diesel blends are found more than neat diesel. To reduce the NOx, EGR is employed, which results in reduction of NOx considerably, whereas other emissions, i.e., CO and Soot, get increased with increase in EGR rates. Soot for WPO-diesel blends is higher because of aromatic compounds present in plastic oils. Brake thermal efficiency (BTE) of blends is found to be higher compared to diesel.
