What is What is Green ComputingGreen Computing??
The positive (or least negative) relationship between the physical computer and its impact to the environments in which it moves through from cradle to grave

Green Computing – Why?Green Computing – Why?
Growing public environmental awareness
Increasing impacts on environmental and human health
Corporate social responsibility

Manufacturing – Fossil FuelsManufacturing – Fossil Fuels
Average desktop computer with monitor requires 10 times its weight in chemicals and fossil fuels to produce
240 kg of fossil fuel for CRT monitor (United Nations University)
266 kg of fossil fuel for LCD monitor (Williams, 2003)
![Page 6: Green Computing: The Environmental Impact of Desktop Computing Catherine Steeves Associate Chief Librarian, ITS Gillian Maurice Sustainability Coordinator.](https://reader033.fdocuments.net/reader033/viewer/2022061306/55147a98550346b2598b477e/html5/thumbnails/6.jpg)
ManufacturingManufacturing –– Monitors Monitors
CRT – lead and zinc leachate mean monitors are hazardous waste (Lee et al., 2004) Lead: bioavailable in soil - can attack proteins
and DNA, as well as interfere with nervous system function (Bechara, 2004; Needleman, 2004)
LCD – 4-12 mg mercury /unit (Williams, 2003)
Liquid crystals – polycyclic or halogenated aromatic hydrocarbons, 588 different compounds 4% have potential for acute toxicity, but show no
mutagenic effects in bacteria tests (Williams, 2003)

Manufacturing – Other ToxinsManufacturing – Other Toxins
PBDE – similar structures to PCB and DDT Bioavailable, environmentally persistent,
biomagnifies in blood, fatty and liver tissue (Domingo, 2004)
Extraction impacts – refining of petroleum for energy and plastic, mining and smelting of metals
Solvents in microchip fabrication – hydrochloric acid, hydrofluoric acid, arsenic, benzene and hexavalent chromium (Williams, 2003)

Short product life expectancy (2-4 years)
Same toxins in manufacturing process can cause environmental contamination
Human health risks Lead, barium, chromium, CNS
disruptors etc. (Baul, 2002)

Computer ProcurementComputer Procurement
Typical computer procurement selection criteria : functionality and specifications required
by the user commercial aspects that offer best value
(best combination of functionality, price, service and other desired criteria)
compatibility with existing equipment and use

Best Practice - DisposalBest Practice - Disposal
Current UG e-waste disposal program represents a best practice
E-waste is divided into two separate streams, CRT monitors and all other electronic equipment
● General e-waste is sent to Production Works where it is dismantled and redistributed to scrap companies and recyclers
● CRT monitors sent to an environment friendly Toronto-based company
![Page 27: Green Computing: The Environmental Impact of Desktop Computing Catherine Steeves Associate Chief Librarian, ITS Gillian Maurice Sustainability Coordinator.](https://reader033.fdocuments.net/reader033/viewer/2022061306/55147a98550346b2598b477e/html5/thumbnails/27.jpg)
Recommendations Recommendations –– Disposal Disposal
Maintain current program, plus:
Obtain suitable space for storage of e-waste and monitors
Develop and implement methodology for tracking tonnage diverted from landfill
Formalize reuse and reallocation procedures and policies
