Equipment Collected

National totals

946 tonnes of e-Waste were collected from the 33 drop-off sites (and approximately 200 schools) participating in eDay 2008. Summary statistics are as follows.

Overall tonnage 946 294**

* Miscellaneous equipment includes: power supplies, speakers and any other electronic equipment.

** Based on equipment count on eDay; shipping weight was 415 tonnes.

Average equipment weights

The following average equipment weights based on information supplied by recyclers and equipment collected during the pilot eDay in 2006 were used to calculate the total tonnage at each collection site, based on the number of items counted:

Monitors 16.5 kg
Desktop computers 12.46 kg
Peripheral (including printers) 6.84 kg
Cellphones 0.1 kg

Equipment mix by weight

Using the equipment average weights in Table 3 and the total equipment quantities, the overall equipment mix by weight is summarised in the following pie chart.

Figure 1: Total weight representation

The pie graph shows the proportion of total equipment weight represented by each equipment type. Monitors comprised the greatest equipment weight at 54%, followed by computers at 33%. Printers made up 13% of the total weight and cell phones 1%.

Equipment tonnage by eDay area

The total number of cars as well as the quantity and weight of e-waste collected, as estimated on eDay, is summarised in Table 4. The projected figures were used for planning purposes and were based on averages from 2007 and scaled to the number of households in each collection area. In areas running their second eDay, an awareness factor of 50% was added to the projection; this was based on the Wellington experience between 2006 and 2007, where the number of cars doubled. The percentage variation is calculated from the ratio of actual: projection numbers. Percentage variations less than 100% mean that the actual numbers were less than the projections and variations above 100% mean that the actual numbers exceeded the projections.

Some of the very large variations are because the actual numbers are quite small, e.g. Amberley. Auckland and Christchurch fell well below projections most likely because of the late start and low level of promotion in these two centres. However, for most centres, the actuals were sufficiently close to projections to ensure that adequate provision was made for site logistics and e-waste transport.

Equipment mix by eDay area

The quantities of each type of equipment collected and the number of cars for each eDay area is summarised below. The variation in the average number of items per car is most likely being influenced by the amount of equipment collected from schools before eDay, or in some cases, collected during the year and stored at the collection site until eDay.

e-Waste by eDay area

The percentage of e-waste collected by area is summarised in the table below. This is also expressed as an average weight per 1000 households. Some of the averages are distorted by the local collection arrangements. While most of the figures represent on-the-day collections and include school collections, some sites collected e-waste progressively throughout the year and used eDay as a means of removing and recycling this material, e.g. Wanaka, Amberley and Wairoa, although in the case of Wairoa the high average tonnage was a direct result of school e-waste being stockpiled over a number of years.
