I was pottering around at work on the Sunday night of a long Easter weekend and decided to fix a set of tool drawers that came in for recycling. Yep, we get all sorts of things coming in for recycling!
Ecotech Services has needed a set of tool drawers for a while and I have been looking out for a suitable second hand bargain. And then these turn up!
The bottom drawer was a bit hard to close. Turns out the drawer runner had lost its bearings. All but one of the ball bearings on the runner were missing.
What are the chances of getting a new runner for it? Possibly not good but repairing is usually the first option for me. So I need some 3.8mm diameter ball bearings to fix it. We have got things that look like short drawer runners in stock that have been salvaged off all sorts of things, including monitor stands and photo printing kiosks. They would a good source of replacement ball bearings. The first one I pulled apart had 4.8mm ball bearings but I got lucky on the second one. It had the 3.8mm ball bearings that I was after.
The drawer was easy to get out. There are two plastic clips that act as end stops and can be moved to get the drawer out.
I cut the end off the sacrificial runner to get the ball bearings out. I then had to remove the end clip on the tool drawer runner to take out the ball bearing holder and I then added the replacement bearings to it. I used bit of grease as a “glue” to keep all of the bearings in place while getting it back on the runner. It was then a matter of putting the runner end clip back on and sliding the drawer back in.
Ecotech now has some better tool storage in our mechanical work area!
We had a cheap Homemaker brand HT7145KM heater come in for recycling. This one had two of the halogen heating lamps rattling around in the bottom because the ends had shattered and the third on was on the way out as well. I thought I would take it apart for a bit of a laugh. And look what I found.
One of the case screws had pierced one of the wires, in this case it was carrying the voltage going to the oscillating motor. This is pretty poor manufacturing quality to say the least! Fortunately the screw is recessed about 20mm down a hole otherwise it would be a serious safety issue.
Another worry is that if the wire strands were cut by the screw would the remaining wires have created enough heat to melt and burn the plastic? Possibly not given that the oscillating motor is quite low current.
This box of stationary items came in with one of our e-waste recycling consignments.
It was going to be thrown out but our staff member said we would take it. It was unneeded due to a reduction in overseas student numbers and that is due to COVID-19.
Lincoln Envirotown is holding a repair cafe event on Saturday the 4th of December from 10am to 1pm. As well as bikes and clothing repairs to appliances, computers, and anything else that is electrically powered will be offered.
As a means of promoting the repair industry Ecotech Services is once again offering free repairs or evaluation to a wide range of faulty electrical, electronic and computer equipment on the 2021 International Repair Day.
The event will be held at our premises on Saturday the 16th of October between 8:30am and 5:00pm at 139A Wordsworth St in Sydenham, Christchurch.
The free repair offer does not include any parts that may be needed and if time is limited the repairs may not be completed. The repairs will be carried out by experienced technicians and where needed will be carried out by registered electrical workers.
At this stage the countries that Ecotech Services is directly involved with in is only Australia. Our downstream recyclers would be sending processed e-waste to a number of countries. Note that exporting e-waste is covered by the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal as well as a few other international agreements. The countries that our downstream recyclers export to is documented on the EPA website.
We use reputable, well established organisations for downstream recycling and we expect that they comply with relevant legislation. I have anecdotal evidence from about fifteen years ago that e-waste was likely to have been exported illegally. I recently asked for auditing and compliance information from our downstream recyclers and the information was either not available or not forthcoming.
To answer your question as to where it all ends up is difficult to answer since the reverse supply chains for recycled materials is probably as long as those for the initial manufacturing of the items.
The items we receive are either refurbished, stripped for parts, or stripped of recyclable material. Items and recovered material are then sold with the waste going to landfill.
At present we do not have any external auditing of our processes. It is too expensive, not required, and takes time and finances away for the actual task of minimising the environmental impact of e-waste. See our auditing and certification pages.
It is impossible to give a definitive and quantitative answer to your question. To give an answer even approaching a worthwhile analysis would mean that we would have to either have a volume of e-waste that is simply not available to us at present (or indeed the whole industry) or we would have to charge our customers a ridiculously high price to recycle the e-waste
As you can see from the matters described above you simply cannot do an accurate full lifecycle analysis of your equipment. In my opinion doing a full lifecycle analysis of e-waste in New Zealand at present is not a worthwhile exercise.
Ecotech Services occasionally gives equipment to groups and individuals to dismantle to foster education about technology and the environment. We recently gave some equipment to the St Martins Scout group. Here is a report and photo from Alex Head, the St Martins Scout Group Cub Leader.
The St Martins Cubs group were excited to learn about electronics while disassembling electrical goods including speakers, computers, DVD drives and more. The cub group comprised of 50 children aged between 8-11 years of age, who over two separate nights, took apart and sorted the electronics and computers into five different components, cables, circuit boards, plastics and non ferrous and ferrous metals.
The children, under supervision by the St Martins Cub leaders loved the challenge of discovery, working together in their Sixers groups, they solved the puzzle of how to undo and take apart the goods, and delighted in the exploration of circuits boards and the gold and silver within.
The educational aspects included learning about the different metals, ferrous and non ferrous, where circuit boards go to be recycled and understanding the role we can all play in environmental protection by correctly repairing or repurposing and disposing of electrical goods.
Special thanks to Ecotech Services who provided over 50 broken electrical goods, enough for one item per child, and educated the Scout leaders to make this possible. I learned a lot and we certainly hope to be able to assist in future to help prevent many of these components from ending up as landfill.
