‘Large household appliances, as ovens and refrigerators, formerly finished with white enamel, but now often
colored’
What are White Goods?
• 0.6% unable to afford a washing machine• 6.5% unable to afford clothes dryer• 8.6% unable to afford dishwasher
A white goods refurbishment program can Greatly reduce prices and make necessaryWhite goods available to all.
For example: • A standard new Bosch washing machine sells for ~479.99 (D.I.D. electrical) [2].• A refurbished Bosch washing machine sells for 160euro from Budget Appliances in Dublin [3].

EOL Decision1. Re-use the product (no increase in energy usage for manufacture).2. Purchase a new product (note the rise in energy due to manufacture).3. Throw it away
The amortization period is the time taken from when the decision is made to change or re-use the product (1 or 2) until the energy usage for purchasing a new product becomes less than that of a reused product (3).

Case Study - Environmental• 60˚c wash with 6kg load• Manufacturing energy,
3508MJ• 220 cycles per year• Recommended amortization
period 6years
Results:• For ‘A’ and ‘B’ rated washing
machines re-use would be the preferred EOL strategy
• ‘C’ rated machines, when used at a medium or low intensity, re-use is best strategy

Case Study - Economic• New machine 300euro,
refurbished 100euro• 20c per kWh• No water charges
Results:• From an economic
standpoint, ‘A’, ‘B’, ‘C’ as well as medium/low intensity ‘D’ and even low intensity ‘E’ would be suitable for reuse

• The US EPA has estimated that 10,000 tonnes of material creates 1 job at an incinerator plant, 6 at a landfill, 36 at recycling centres and 28-296 in the re-use industry.
• At a refurbishment plant in Northern Ireland 16 people were responsible for processing 6395 machines, of which, 4605 were reused.
• 2009 almost 25% of Irish households were in arrears on bills compared to 10% in 2008
Social Issues
![Page 8: ET4407 Problem 2 Presentation](https://reader033.fdocuments.net/reader033/viewer/2022061617/56815d29550346895dcb2292/html5/thumbnails/8.jpg)
• A constant supply of parts, sometimes no longer in production would be needed.
• 42% of the Irish population and 46% of the UK would be willing to purchase second hand electronics.
• Previous case study shows how ‘A’ and ‘B’ are favoured for re-use, currently 90% of washing machines are ‘A’ rating so re-use of low rated machines would not be a massive issue.
Sustainability of a re-use scheme
