Streamlined life cycle analysis of a Tim Horton's style paper cup
Transcript of Streamlined life cycle analysis of a Tim Horton's style paper cup

Paper Cup Streamlined Life Cycle Analysis of a Tim Horton's style Paper Cup Risk Characterization Matrix 1 million paper cups are sent to landfills from Toronto every day
-Entec Consulting 2009 Process Matrix Resources Anatomy of the Paper Cup LID
Made of polysterene and is 100 percent recyclable.
milled using elemental chlorine-free process
comes from FSC ( Forest stewardship Canada) or SFI ( sustainable forestry initiative)
Cup liner made of PET ( polyethylene)
water based ink with no heavy metals
The whole cup has recently been remade into trays through a new Tim Hortons initiative. Process Sequence Diagram - Manufacturing Process Each year, 1.6 billion takeout coffee cups end up in land fills needlessly because most Canadians have not switched to using travel mugs.
-Vancouver Sun 2010 Highest carbon Emissions from Distribution Fleet at 50 percent
Energy use – fossil fuel (non-renewable) resources used in processing and transportation of paper products.
Risk factor for energy: Time and Distance
Gaseous residues: emission dues to long distance transport and energy use in pre-manufacturing.
Large time, distance, and peril risk factors
Material choice: Time to replace paper products, non-renewable fossil fuels used in processing
Risk Factors are time, distance and peril Risk Analysis: Predominant Stressors Largest risk stages:
Pre-manufacture: virgin paper and plastic
Product Delivery: Emissions from transport and wasted packaging Risk Analysis: Predominant Stages Dominant Stressors Product Assessment Matrix Cup-to-tray initiative
Tim Horton’s are working with local waste management companies to expand recycling program Tim Horton’s Recent Initiatives for improved sustainability 215,112 tonnes CO2 per year 2011 by Tim Hortons combined restaurants and distribution.
Paper mills, saw mills, logging industry has huge inefficiencies and emissions.
As transportation cost go up, it will become more worthwhile to have more distribution centers and less transportation
Transportation largest contributor to CO2 / gaseous residues
Use of hybrid / electric fleet vehicles
Advanced Particulate Filter / Catalytic Converter
GenCat (uk based exhaust after treatment specialist) recommends regenerative particulate filters (where the soot, being primarily carbon) is captured, and combusted completely using catalysis) and catalytic converters (which convert CO and unburned Hydrocarbons)
– Gencat Ltd., 2010
Virgin Paper production largest contributor to liquid, solid residues
Could use recycled paper or plant based plastics
Manufacture of paper should use chlorine free bleaching process
2008 -2011, improvement of 6.74% fuel efficiency was achieved in Tim’s transport vehicles ($1 million in savings)
Improvements: in-cab heaters, speed cap, re-routing, EPA-certified engines
