• Life and death

    A stack of tower style PCs.
    These patients are waiting patiently to be triaged.

    When we receive our patients they all go through a thorough and careful process, and we are usually able to give them a longer, healthier life.

    Sometimes the sheer numbers overload our facilities and so we firstly carry out a quick triage of all the incoming patients. Some of the better Windows 7 and 8 machines go straight to the operating theatre for a Windows 10 upgrade to give them a new lease of life. Core 2 Duo patients are deemed to need palliative care but we euthanise them with the dismantling process. There is rarely a need to keep doner parts from them for other sick PCs. Some of the Windows XP patients are still quite healthy after quite a long life and a few humans like and need their company. We give them a new lease of life with a wipe, an operating system reload, and sometimes a little cosmetic surgery.

    During the triage we find that some patients are DOA, in some cases it is because they have been butchered for parts.

    A dusty PC
    We euthanised this patient.

    It is disappointing that we get some patients who have led an unhealthy life. They quite obviously have been cooped up in a dusty environment and kept working all day and all night. This leads to overheating and possibly to a premature death.

    We do the best we can with all our patients by reviving them and ensuring that they can be a healthy part of the home and the workplace. However, it is quite depressing to see that some of them will never again be gainfully employed. A very satisfying part of our job, on the other hand, is to take some of the geriatric computers into our care. We know full well that they will never be employed again but being so interesting we keep them ourselves for the good company they provide, or we pass them on to those who will lavish them with love and care and attention.


  • Market report: Paint pails

    After a decade of slow demand the market for second hand paint pails has strengthened.  Market analysts working in the second hand paint pail market have seen a supply side issue.  This appears to be largely due to a shortage of plasterboard in the construction sector leading to a lower demand for paint.  It was announced that there could be 100 shipping containers of plasterboard arriving to cover the shortfall in local production.

    The supply of the pails is now sporadic.  Creative Junk are experiencing high demand with them “flying out the door”.  Retail prices are either $2 or $4 on Facebook and are not readily available on the Trade Me auction site.

    Alan Liefting the Paint Pail Purchasing Manager at Ecotech Services, has been watching the paint pail market for some time.  “We have been using the pails for storing all manner of itmes from our recycling operation for a long time,” said Mr Liefting.  “They were easy to get. People were glad to get rid of them. Now we have to pay for them!”

    The reputable paint supply merchants rarely have empty paint pails and the ones withat have paint residue are sent away for recycling.  There is speculation that there is stockpiling of paint pails to reduce the supply and attempt to manipulate the market but wthere is no concrete proof of this.

    (Whilst this is my attempt at humour it is largely based on facts – except my company role!)


  • Ecotech comes up with the goods!

    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!

    tool drawers

    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.

    Close up of runner.
    This is the ball bearing holder now with its full set of bearings.

    Ecotech now has some better tool storage in our mechanical work area!

     


  • Peter’s homemade e-bike

    Check out Peter’s homemade e-bike.The battery pack housing is from a recycled NZ Post e-bike battery that Peter repacked with recycled 18650 cells.  The battery pack housing and the 18650s are from us here at Ecotech Services.  Peter sourced the hub motor from overseas and it was easily retrofitted to the Marin bike frame.

    Good on ya Peter!  Nice job!


  • TiVo recycling

    The TiVo service is shutting down as of 31 October 2017.  It is unfortunate that that TiVo has only been in New Zealand for such a short time making the set top boxes redundant.

    If you have a CASPA wallet go to mytivo.co.nz to organise what to do with the remaining balance.

    Ecotech Services is able to recycle the redundant set top boxes, remotes, and related items.

  • Battery recycling in Lincoln

    In what may be a first for a supermarket in New Zealand, the Lincoln New World now offers a battery recycling service.  The scheme is an initiative of Lincoln Envirotown and has funding from the Sustainable Initiatives Fund (SIFT).  Dave Fitzjohn, the project manager at Lincoln Envirotown, has been the driving force behind this worthwhile scheme.

    Ecotech Services is proud to be associated with this battery recycling initiative.

  • A throwaway society

    We really are in a throwaway society.  We have  been calling it that since the 1950s and all of this technology of ours is an increasing part of the throwaway society.

    I had a Canon PIXMA MG2960 ink jet printer/scanner come in for recycling.  I can’t find any date code on it without stripping it down but it looked brand spanking new.

    Apparently the paper was not feeding.  I was going to see if it was fixable but it had no ink cartridges.  I then jumped online and checked it out.  It sells for a mere $32.99!  And it is still a current model!  I did know that these low end inkjet printers are cheap but I just can’t get used to the idea of these low prices.  These printers sell for less than the minimum service fee that most repair companies charge out.

    This is nothing new of course.  Back in the early 2000s I worked for a company that did a lot of printer repairs, including low end inkjets.  The minimum service fee was $33.75.  It got to the stage that we had to charge that fee up front because we were left with too many cheap inkjet printers that the customers did not want to have repaired.  So not only was the company out of pocket for the time taken to do the diagnostics for a quote but there was also the disposal cost of the unwanted printer.

    It is easy to see why the amount of e-waste is rising and the repair industry is in decline. We really are in a throwaway society.

  • Carpet downcycling and hot water cylinders

    We had a hot water cylinder come in for recycling.  It is not something that we have had before but I knew that they have valuable copper as the actual cylinder.   It was pulled out of a house because it had a leak in the base.  A date written inside the cylinder for an element change said 1986 so it is at least 30 years old.

    Before I started pulling it apart I saw some wadding that looked like carpet.  Sure enough, when I took the ends off this is what fell out:

    hot-water-cylinder-insulation

    You don’t see shredded carpet used in modern hot water cylinders.  The newer ones are pumped full of insulating foam from what I gather.  Sure, specialist insulating foam is probably better than shredded carpet as an insulator, but it is not a recycled product.  And can the foam be recycled at the end of its useful life?

    The carpet has been downcycled, which is  recycling into something of less use that the original thing.  Downcycling is better than not recycling at all but it is not as good as recycling it into something that can go back into what it came from originally (or an equivalent).

    I don’t think shredded carpet has any real use so unfortunately we will have to dump it.  Damn, it looks like our monthly mass balance will be on the environmental debit side!

  • Poor quality Ozito cordless drill charger

    An Ozito OZCD12V1A cordless drill came in to us for recycling and it looked like it had hardly been used.  Rather than recycling it I thought it might be a good candidate for repurposing or rehashing with different batteries.

    Photograph of a printed circuit board inside a power pack.
    Never been soldered!

    On inspection I found that the NiCd batteries were leaking (this may or may not be an issue since I have no idea how old it is) but more importantly I found that a wire on the transformer in the power supply had never been soldered at the factory!  It didn’t help that the circuit board on the transformer was only flimsily attached.

    The drill was hardly used, possibly because that batteries could not get charged?

    I don’t know how the mechanical side stacks up but the electronics is pared back to an absolute minimum.  Firstly, there is no filter capacitor in the charger power supply.  You can get away without one in some cases but it is usually good practice to have it.  The NiCd charging circuit is really basic.  Maybe even too basic to the extent that it may damage the NiCd cells.  It consists of six components, and two of those are indicator LED’s.  Having the two LED’s (one red and one green) is one positive thing.  Sometimes cheap products only use one.  Temperature sensing of the NiCd cells is also non-existent and that, coupled with the lack of battery voltage detection, means that the really basic charging regime will shorten the lifetime of the cells.

    It is a real shame that consumers demand cheap products and manufacturers supply them.  It is creating unnecessary environmental problems
