Streamlined LCA of paper towel end of life options for UBC SEEDS : recycling vs. composting
This study was performed for the University of British Columbia Alma Mater Society (AMS) as part of the Sustainable
Ecological Economic Development (SEEDs) program. Although paper towel is proven to be an environmentally damaging
method for drying hands, relative to other methods such as hand dryers, many buildings on the UBC campus must still
provide paper towel for technical or sanitary reasons (Gregory, 2011). In particular, the AMS is concerned with how to
minimize the environmental footprint of paper towels used in the Student Union Building (SUB). This streamlined LCA
provides a comparison between end-of-life options for paper towel used in SUB bathrooms, in particular for recycling
and composting. The study used a closed loop process for recycling, and an open process with avoided burdens for
composting. Overall it was determined that when considering impact categories of solid waste, electricity use, water
depletion, fossil fuel depletion, climate change, and human toxicity, composting is the better option for all categories
except for electricity consumption. Avoided burdens calculated to not change this result. For example, the Climate.
Change impact for Recycling was 1,039 kg COâ‚‚ eq while for composting it was 734 kg COâ‚‚ eq (874 kg COâ‚‚ eq without
avoided burdens). Additionally, a basic life cycle cost analysis was completed, and composting costs to the university are
less than those for recycling. Annual costs for composting were estimated at 16,120.
