AB  - A common challenge for the anaerobic digestion (AD) of food waste (FW) is the 
      contamination by disposable plastic materials and utensils. The objective of this 
      batch study was to investigate the effects of disposable plastic materials - 
      polystyrene (PS), polypropylene (PP), high density polyethylene (HDPE) and wooden 
      chopsticks (WC) on the AD of FW. Results showed that methane production from the 
      AD of FW was inhibited to different extents when different materials were present 
      in FW. PS and PP were found to reduce methane production from food waste more 
      than HDPE and WC. The reduction in methane production was hypothesized to be due 
      to the production of toxic plastic by-products or due to reduced contact between 
      microbes and FW. Pyrosequencing and Field Emission Scanning Electron Microscope 
      (FESEM) results indicated that the reduction in methane production was more 
      likely due to the interference of good contact necessary between microbes and FW 
      for biodegradation, and that the biological processes of AD were not affected by 
      the contamination of plastics. Greater reductions in methane yields were also 
      observed when the surface areas of the disposable materials were increased. 
      Studying the effects of disposable materials on the AD of FW would provide plant 
      operators with more information that could optimise the process of resource 
      recovery from food waste.
