Comparison of end of life options for waste paper towel at the University of British Columbia

University of British Columbia. Sustainability Office

In this paper, three paper towel disposal options were evaluated – landfill, compost and gasification (Nexterra Plant). The seed office would like to find that if it is feasible that UBC collects the paper towel waste and sends it to Nexterra Plant to produce syngas. Below is the summarized of the findings. Economy: $0.073/kgPT landfill, $0.079/kg compost, and -0.062 gasification; thus, gasification is economic feasible. Environement: 1.882kgCO₂/kg PT landfill, 0.7577 kgCO₂/kg PT, and 1.15kg CO₂/kg PT; thus, the compost option is the most environmental- friendly option. Social impact: 9.243 kg/year/mg/m³,5.85 kg/year/mg/m³,and 332 kg/year/mg/m³; thus, the composting option also has the lowest health impact. Based on the finding, the compost option is the best based on the overall consideration in this paper; however, the gasification gives economic savings; even though it is not as environmental-friendly as the compost option, it is feasible.
