Clever trash bin

You've claimed knowledge of the logistics. Are you assuming to know the logistics of this particular situation the basis of the sales ad for these compacters?

Nope. It doesn't really matter what we're talking about, the modeling of the system is pretty similar.

And I claim knowledge about logistics in the way you claim to be an environmental expert. Actually less. I claim to know a thing or two about logistics, and you claim to be an expert...

"Real world" modeling is, in the end, just modeling. It's at best an approximation, and only as good as the originating data that initializes the study. Without any "audit" on the effectiveness of such trash compactors, you could very well see no reduction in pick-ups.

Yes, it's all predicated on the assumption that the cans actually compact. Thanks for that insight. I guess I implied that was one of my assumptions but didn't state it explicitly.

Yes it is. Modeling fails to take into consideration unknown variables. So some weeks, some compactors could easily fill more quickly than others - unless you presume to know the exact patterns and habits of the users. Dealing with such variability would require a visit for pick-up to prevent overflow, or possible break-down.

That isn't what I said at all. What I said was that the problem is the same for either kind of trash can. In other words, that dimension doesn't make a compacting trash can better or worse than the ordinary can. As it is, rather than be emptied when they are full, trash cans tend to overflow and people litter instead. So, if the collection frequency remains the same, it's probably going to result in less litter (since it will be less likely for the trash cans to reach their capacity between collections).

The goal seems to be to reduce operating costs rather than improve service. So long as compacting cans are no more likely to be filled to capacity before collection than ordinary cans, the point is moot. Collection frequency can be adjusted to target any level of service desired.


Which means the that all the promises concerning fuel consumption and so on are being way oversold by the manufacturer.

Well, perhaps. To be fair, this is a quick blurb written up by a magazine. The company may well have provided all the underlying assumptions but the magazine omitted them for brevity. I would say that even a mixed fleet would lower the number of collections per trip and total distance traveled.

No doubt you'd want to see a new tax in Toronto to support that job.;)

If it were up to me, I'd offer you the job. But I'd want you to live in the city first.

Isn't that illegal?



I guess your concern about the particular reliability, etc. of the trash can isn't anything I'd be concerned with at this stage. That is something that would have to be examined as part of a detailed CBA. I thought the concept was interesting enough to justify posting here. I only got into the logistics discussion because you misunderstood the claim about reduced operating costs.

To what? Your sentence is vague.

This appears to have gotten under your skin in a big way. You are taking all this too personally. Also, I've never claimed to be an environmental "expert" as you assert. That being said, I know a thing or two about environmental issues.

Yes, it's all predicated on the assumption that the cans actually compact. Thanks for that insight. I guess I implied that was one of my assumptions but didn't state it explicitly.

No, you missed it. The point is that these compacters will inevitably be used at different rates over time. Some will be filled faster than others, and at different times, so they will have to be checked and emptied more regularly. The easiest and cheapest way to do it is while servicing the larger number of cans.

Trash cans can overflow. So, presumably, can compactors that get over-filled. The point you claim as being moot is the one where visits to empty the compacters will most likely be the same as visits to empty trash cans. As you suggest, the system will be mixed (lots of trash cans compared to fewer compacters), so frequency of visits to empty all of these won't change. Also, try to remember that trash cans are not machines, compacters are. That means that they require service checks to maximize their efficiency, or to replace units that will inevitably break down (big savings there, yeah).

Well, perhaps. To be fair, this is a quick blurb written up by a magazine. The company may well have provided all the underlying assumptions but the magazine omitted them for brevity. I would say that even a mixed fleet would lower the number of collections per trip and total distance traveled.

You might want to view the company video. In any mixed system of cans versus compactors, the cans (outnumbering the compactors) would lead the way in terms of frequency of visits to empty. The status of the compactor will not be known otherwise.

Isn't that illegal?

Well, for a guy (you) who argued so ardently for the Toronto land-transfer tax without actually living in the city, I'm only holding you up to residing in the place you want taxed. Then you can have a job to finally pay those taxes. ;)

I only got into the logistics discussion because you misunderstood the claim about reduced operating costs.

Maybe you should examine the claims of the company. Also, the burden of proof is on you to show that operating costs will be reduced with these machines. Among other things, I've stated that in a mixed can/compacter system, visits would be determined by servicing the cans. I've pointed out that rates of filling compacters would differ from one location to another over time, and this would require visits to check on their status (to prevent overflow or breakdown). You've opted to ignore these things. I've pointed out that these compacters are machines, and machines must be checked, serviced and eventually replaced. That ain't cheap.

Add to all of that, compacters actually don't address the overall quantity of garbage. So they do nothing to address the actual source of the problem (trash).

So no, there is no significant cost-savings to be found.
 
To what? Your sentence is vague.

To other logistics models. Servicing navigation buoys, say.


This appears to have gotten under your skin in a big way. You are taking all this too personally. Also, I've never claimed to be an environmental "expert" as you assert. That being said, I know a thing or two about environmental issues.

I think claiming authority as a result of conducting studies for government is essentially claiming to be an expert. Nevertheless, you didn't really get under my skin. You have a penchant for condescension that I don't appreciate.

No, you missed it. The point is that these compacters will inevitably be used at different rates over time. Some will be filled faster than others, and at different times, so they will have to be checked and emptied more regularly. The easiest and cheapest way to do it is while servicing the larger number of cans.

Trash cans can overflow. So, presumably, can compactors that get over-filled.

That is true of either normal or compacting bins, therefore, it isn't a useful basis for comparison. Having a larger capacity means that for a given service frequency, the larger can is less likely to overflow and less litter will result.


The point you claim as being moot is the one where visits to empty the compacters will most likely be the same as visits to empty trash cans. As you suggest, the system will be mixed (lots of trash cans compared to fewer compacters), so frequency of visits to empty all of these won't change.

Well, it should. Since they have higher capacity, they won't need to be emptied as frequently. Think about it some more. If lower volume cans are visited once per week, while high volume cans need to be emptied daily, there is an advantage to increasing the capacity of the higher volume cans so they can be emptied at a reduced frequency. Do you disagree with this? (Honestly, I don't understand what your quibble is.)

Also, try to remember that trash cans are not machines, compacters are. That means that they require service checks to maximize their efficiency, or to replace units that will inevitably break down (big savings there, yeah).

You might want to view the company video. In any mixed system of cans versus compactors, the cans (outnumbering the compactors) would lead the way in terms of frequency of visits to empty. The status of the compactor will not be known otherwise.

I don't know what you mean by that last statement. Presumably, the highest volume locations would benefit from increased capacity, either by reducing the collection frequency required to something more in line with the rest of the bins, or by less resulting in less overflow due to exceeding capacity.

Well, for a guy (you) who argued so ardently for the Toronto land-transfer tax without actually living in the city, I'm only holding you up to residing in the place you want taxed. Then you can have a job to finally pay those taxes. ;)

I'm not sure I argued 'ardently' for it (not what I would consider an ideal way of raising revenue). Living in the city would also not mean that one paid the land-transfer tax. Also, you'll be pleased to know that I have a job--though for the right price I'd be willing to audit trash cans on weekends.

Maybe you should examine the claims of the company. Also, the burden of proof is on you to show that operating costs will be reduced with these machines.

I have no such burden. I don't particularly care what the company has to say (I'm not buying, and analyzing whether they should be bought). Their implementation of the concept may or may not be good. I liked the concept.


Among other things, I've stated that in a mixed can/compacter system, visits would be determined by servicing the cans. I've pointed out that rates of filling compacters would differ from one location to another over time, and this would require visits to check on their status (to prevent overflow or breakdown). You've opted to ignore these things. I've pointed out that these compacters are machines, and machines must be checked, serviced and eventually replaced. That ain't cheap.

Right. If the machines are unreliable enough that they are more likely to break down between visits than reach capacity, they probably should not be used.

I have also not ignored that cans fill at different rates. I mentioned that this would motivate a mixed fleet, if anything. Yes machines require service, but I rather doubt that that would dominate operating costs (visits every day to ensure they working properly?). All I've said is that there would need to be further analysis done to see whether it makes sense. In terms of the collection cost component (to spell it out, ignoring cost of the cans, maintenance and replacement), it is pretty clear that it would lower cost due to more efficient collection. We can talk about that if you want. I don't have any interest in whether the cans are reliable or not, because that is all just speculation.

Add to all of that, compacters actually don't address the overall quantity of garbage. So they do nothing to address the actual source of the problem (trash).

So no, there is no significant cost-savings to be found.

That does not follow. Not even close. Sort of like arguing that there is no point in trying to optimize the delivery of food from farms to stores, since the real problem is that people don't grow their own food. Ergo, there are no opportunities to significantly reduce costs in food transportation.

Furthermore, that problem is beyond the scope of the what the can was designed to solve. Maybe we should design a motion sensitive trash can that will give people guilt trips when they deposit waste?
 
You have shares in this company or what?

I think claiming authority as a result of conducting studies for government is essentially claiming to be an expert. Nevertheless, you didn't really get under my skin. You have a penchant for condescension that I don't appreciate.

Think what you want. I've done what I've done and nothing you say will change that. The fact that you brought it up points directly to it getting under your skin. You've claimed expertise about logistics, but you still miss the key points here.

Oh, if you find debate with you condescending, try getting a thicker skin.

That is true of either normal or compacting bins, therefore, it isn't a useful basis for comparison. Having a larger capacity means that for a given service frequency, the larger can is less likely to overflow and less litter will result.

That is why the frequency of visits to empty compacters won't be any different than normal trash cans. There is no way to know how full a compacter is, so a visit will be made anyway. Why skip the minority of trash receptacles on the basis of an assumption about full they may or may not be?

You are presuming some foreknowledge about how fast a compacter will fill. You don't have such knowledge.

Since they have higher capacity, they won't need to be emptied as frequently. Think about it some more. If lower volume cans are visited once per week, while high volume cans need to be emptied daily, there is an advantage to increasing the capacity of the higher volume cans so they can be emptied at a reduced frequency. Do you disagree with this? (Honestly, I don't understand what your quibble is.)

Again, you don't know if the compacters will have to emptied less frequently. You don't know if any individual compacter will have to be emptied less frequently in any given location that they are situated. All you are operating on is that these devices compact trash. The only way to know their status is to check - which means a visit - which means the deployment of a crew on a regular trash pick-up route. They're already out there visiting the majority of the trash receptacles on a regular route.

I don't know what you mean by that last statement. Presumably, the highest volume locations would benefit from increased capacity, either by reducing the collection frequency required to something more in line with the rest of the bins, or by less resulting in less overflow due to exceeding capacity.

Regular trash bins will set the garbage pick-up schedule. This will happen because these bins will exist in higher numbers. Higher volume or not, the smaller number of compacters would still be visited as frequently because there is no other way to know their status.

I'm not sure I argued 'ardently' for it (not what I would consider an ideal way of raising revenue). Living in the city would also not mean that one paid the land-transfer tax. Also, you'll be pleased to know that I have a job--though for the right price I'd be willing to audit trash cans on weekends.

By the length of your responses, you appear to be sold on these things. Nice to hear you have job, but auditing trash is full-time. Would you like a bike or a truck?

I have no such burden. I don't particularly care what the company has to say (I'm not buying, and analyzing whether they should be bought). Their implementation of the concept may or may not be good. I liked the concept

I have no issue with the "concept" either, I just don't see it being particularly useful. All it has over a regular trash receptacle is that it crushes garbage. It still has to be checked and emptied, it is more expensive than a regular trash bin, it can break down, it must be regularly serviced and repaired, and eventually must replaced more frequently and at greater cost than a regular trash receptacle.

I have also not ignored that cans fill at different rates. I mentioned that this would motivate a mixed fleet, if anything. Yes machines require service, but I rather doubt that that would dominate operating costs (visits every day to ensure they working properly?). All I've said is that there would need to be further analysis done to see whether it makes sense. In terms of the collection cost component (to spell it out, ignoring cost of the cans, maintenance and replacement), it is pretty clear that it would lower cost due to more efficient collection. We can talk about that if you want. I don't have any interest in whether the cans are reliable or not, because that is all just speculation.

What would the costs be for deploying a "mixed fleet?" Would it actually be cheaper? Have you made any inquiries with respect to the scheduling of city crews and human resources? Since there are fewer numbers of compacters, you would still be deploying a regular schedule of workers to visit the majority of regular trash receptacles. You still would also have to factor in extra service visits to compacters - plus technicians and replacement costs, loss, repair and replacement due to accidents, break-downs, vandalism, etc. In reality, you don't get to ignore the other costs. You don't get to ignore reliability issues. Fascination is never a sound basis for the procurement of equipment.

It's hard to see how you can claim lower costs all the while suggesting more analysis be done.

That does not follow. Not even close. Sort of like arguing that there is no point in trying to optimize the delivery of food from farms to stores, since the real problem is that people don't grow their own food. Ergo, there are no opportunities to significantly reduce costs in food transportation.

Furthermore, that problem is beyond the scope of the what the can was designed to solve. Maybe we should design a motion sensitive trash can that will give people guilt trips when they deposit waste?

Of course, why would you not be following it? You are too busy removing reality from impinging on the fascinating world of solar-powered trash crusher and the analysis-free assumption that they will reduce pick-up costs significantly - whatever that is (okay, I admit being condescending here). Since I was talking about trash compacters and not food delivery, I was making a point about how trash compaction does nothing to address larger garbage issues (it follows). I was looking at the problem on a larger scale - and not removing annoying but relevant details that got in the way of unmeasured assumptions that such devices could reduce a little cost from the pick-up schedule.


And I was only kidding about the garbage audit job. I can't offer that to you. Sorry.
 
Hydrogen, the key point you're ignoring is the higher capacity. You're willfully ignoring it. To collect a given amount of garbage over a period time without allowing the can to exceed capacity (assume a constant rate), the smaller the can, the more collections are required. You are arguing that the capacity of the garbage can is irrelevant.

You also ignored my critique of your argument. You argued 'Generating trash is a problem' => 'The cost of collecting trash from public garbage cans cannot be significantly reduced'. That does not follow.

I'm not really in the mood for a quote war right now--I may go back later.
 
You're failing to recognize that there is more to garbage collection than a compacter you like, and some presumed (but unproven) effects that you happen to believe in. As you yourself have noted, compacters would make up a minority of the receptacle system. The majority of normal trash receptacles would then set the schedule, not the fewer numbers of compacters. That means the same numbers of trucks and crews would be out there anyway to service those receptacles.

You've probably noticed that people still put out their trash cans when they are half empty. Crews still empty them into the truck when they are half empty. They won't opt out of returning to that location on the next rotation simply because the garbage can never gets totally filled.

By the way, I didn't "argue," I stated that compacters ultimately don't address the overall trash issue. They don't. In reference to that, you continue to avoid noting that I began the sentence with "add to that." That should make it clear that it is a separate thought. Trash collection is part of a system of waste removal and processing. You neglect this only as a means of diverting attention from the fact that you are busy asserting claims that such receptacles would reduce costs, but admit that any analysis is actually in short supply. You simply believe that these receptacles will do so. Nothing more.
 
I didn't claim that it would reduce costs overall, but that it could reduce collection costs (which is what the manufacturers were claiming as well). Yes that is predicated on them being used intelligently/optimally. Are you arguing that it is impossible that these could lower collection costs? Unless you are, I doubt we are actually disagreeing.
 
There is an overall cost to trash collection of which collection from street receptacles is only one part. What I have been saying is that it's doubtful that these devices will produce any cost reductions. I'm not interested in repeating myself, but collection scheduling will still be set by the larger number of conventional trash bins. That does not even include the cost of collection from homes.

I don't see these devices bringing any savings.
 
Ahandle, I notice that you've responded to a whole slew of threads with these one-line posts that say nothing of significance. It's annoying.
 
I thought about stringing them all together to see if they could be used to form a sentence.

BIG BELLY:

By incorporating solar cells into the top of a trash compactor, Big Belly Solar has created a new urban garbage solution that has already survived four years on the mean streets of Flushing in Queens, N.Y. The compactor cuts garbage collection costs—and pollution from those garbage trucks—80 percent by reducing the need for pickup.

I think they're onto something good here but I don't think some of the designs are very attractive in some of the models shown in the video but more than that I wouldn't dare touch one of those handles to dispose of my refuse. That photo appears to be a shiny new model, imagine what one of these units would look like after a month of use downtown? Perhaps there's a cleaning maintenance program attached to this system? It's an interesting concept, worth the read & watching the video but a mute point for Toronto. We're already committed to the street furniture program for the next what, 20 or so years with the Tonka bins.
 
Besides, here in Toronto somebody would just plaster "Think in Spanish" posters over the solar collectors, anyway.
