The Chair Conservative Harold Albrecht

I call the meeting to order.

This is meeting number 41 of the Standing Committee on Environment and Sustainable Development. We're continuing our study today on the management of municipal solid waste and industrial materials.

We're honoured today to have Mr. Bob Mills appear by video conference from Calgary, Alberta. Bob is well known in many circles for his work on the environment.

Bob, welcome. You understand the process better than we do. You were a chair of this committee for a lot longer than I was, so welcome. You have a 10-minute opening statement and then we'll have some questions from our members.

3:30 p.m.

Bob Mills As an Individual

Great. Thank you very much. This is a new experience for me sitting as a witness, not around the table, but hello to all former colleagues and congratulations for dealing with this issue. It's one I tried as chair and a member of the environment committee to get in the forefront because every single municipality in our country and most other places has this as a problem.

To give a little bit of background, I am 100% opposed to landfills. I think they're ticking time bombs. The liabilities there are tremendous and I began my fight in the early 1970s against landfills.

I used to take my wife on trips to various places. We went to the Netherlands, Spain, Germany, Iceland, Denmark, all over the place, and I would always take her out and show her the garbage facilities wherever we happened to be.

The worst was when I took her to Denmark and told her she would get some shopping in. It ended up we went out from 7 a.m. until 9 p.m. and she only had time to window shop.

It has been a long time. I sat next to the mayor of Vienna and after our banquet we went out and looked at a garbage facility, so it has been a long time.

I've always been looking for an alternative. I think that if you're going to oppose something you had better have an alternative that's better. I've looked at different things and looked at incineration in detail. When they started in the 1970s they were a disaster with what they emitted. You have to remember that for incineration you always have about 30% of slag that now becomes toxic and you usually end up landfilling that.

While scrubbers have improved, they still haven't improved enough as your last witness told you, so incinerators are out. They use too low a heat. They don't destroy many of the contaminants.

Denmark has a great incineration program using straw and wood chips, and district heating. Iceland has geothermal and incineration. Berlin has been drying sewage for over 50 years and using it to provide district heating. There are a lot of examples around the world of different types of processes and different types of incinerators.

When I arrived in Ottawa in 1993 I asked my employee, Louise, what the federal government does about garbage. She said, “Well, why don't you call Environment Canada?” I did. They told me it was a provincial matter. I wrote all of the provincial environment ministers and I got an answer back from all of them, surprisingly, and they said that they would really like to look at new technologies, but it's a municipal problem so I should talk to the cities.

I wrote to almost all the major cities in Canada and got a lot of replies. The basic reply was, “We would love to try some new things, but we don't have the money, we don't have the technique, and we don't have the staff that can explore it, so why don't you talk to the province?” Then they said, “Why don't you talk to the feds because that's where you are?” It has been a great circle of nobody wanting to take responsibility.

In the early 1990s I visited Barcelona. Spain had put in a law against landfills, so I thought that's the place I had to go to. I looked, with the help of HERA, the big garbage people there, at the mining process and the piping and so on. I also was told about a problem that they had when they opened up a landfill and a chemical cloud came out. In a landfill you never know what the chemical makeup will be. We like to think that people don't put batteries and stuff like that in there, but of course they do.

Then I discovered there was a new technology that they were looking at. It was called Plasco. I found out it was a Canadian company and then I got involved in looking at what their technology was. The big advantage for them was they were using 5,000°C and producing a slag which then could be used for road material and water and so on. In other words they gasified everything with the plasma. I think you've heard about that technology.

In central Alberta I thought I'd better start at home. I went around to all the councils in our area . This is a bit of a case study here. There were about 200,000 people in that area at that time. They were just instituting a new landfill and I was deadly opposed to that and let everyone know.

Then I approached the Red Deer County. They said that they were on side. We had another 10 municipalities on side. The president of Red Deer College at that time chaired the group. We formed a commission and held public meetings. Where we thought we'd get 50 people, we got 500. There was a huge interest.

As a result of that, a contract was drawn up, but then we ended up going back to councils and we heard what the problems would be: “Well, it might blow up. What if it doesn't work?”

It was going to be all private money, but the City of Red Deer made the decision that it would only put 10% of its garbage in because they had a 17-year investment in the landfill. The province put $10 million in, but the project died, largely because of the City of Red Deer. I could give you a lot more details on that.

You have heard testimony from other witnesses which I've gone through. It has been very interesting. If I were to summarize some of that, I would agree with most of it. Garbage is not a waste; it's a resource. Streamlining and modernizing regulations is certainly necessary. For instance, in the province of Alberta, if you have a BSE animal, you have to put it in a designated landfill. You wouldn't be able to gasify it; you wouldn't be able to do anything else with it. You have to change the regulations to modernize them for the 21st century.

We need more data. We need to know what goes into a landfill. I've been part of a team that has opened garbage bags at various landfills. You would be shocked at what's in there. While people know they shouldn't put batteries in, almost every bag contains a battery or two. Of course, those have all kinds of contaminants which seep out.

We should continue the cycle of reuse and reduce as much as we possibly can. I don't believe we should ever end the green box program. We need to change the way we think—now that's a big one—and those public hearings that I went to, I can answer some of your questions later about those.

We need to consider the real cost of a landfill: the cost to the air, what's being given off and the greenhouse gases in particular, and the cost to the water, the groundwater that we are contaminating. The big thing is the future liability from future landowners with the possibility of—and they're finding this throughout Europe and many parts of the U.S.—leachate seeping into their basements, into their land, making their land literally unsaleable.

Technology will be the solution and that's certainly where the federal, provincial, and municipal governments need to focus. You heard about optical sorters, how the seven plastics can be sorted now without using hands. Incinerators are old technology. They use low temperatures to destroy dioxins and furans. You need at least 1200°C. You have air quality concerns. You have so many things being released. You've heard about that.

I would like to tell you a little story. I drove from Orlando to Miami two weeks ago and there were about five or six landfills by the expressway. You could tell at least a mile before you got to one of the landfills and a mile after you went by. The odour from these capped landfills was just unbelievable.

In conclusion, my recommendations would be that we need much tougher standards. We need municipalities, provinces, and feds to stop saying that it's somebody else's responsibility. We need them to take responsibility, to cooperate, and to encourage the new technologies that are out there.

We need more research and development. We need to encourage all of this new technology; some of it will work, some of it won't. SDTC does a great job. Tax credits and accelerated depreciation are other ways that the federal government could be involved.

The big thing that is out there right now, and that you need to look at, is that there are a great many projects. Many people have many ideas. Unless they've gone through the steps of the engineering, the research, the pilot project, the demonstration plant, then the valley of debt where they actually have to commercialize, until they've gone through those steps, you really don't know if you have a technology that will work or not.

I don't think the federal government needs to be cherry-picking one over the other, but they all need an opportunity to really prove that their system will work. You've heard that from other witnesses as well.

In my opinion, from travelling the world and looking at this, including an in-depth study in China of how they can deal with their garbage, technology will be the solution.

With regard to education, we must let people know there's a huge liability out there, that no engineer will guarantee there won't be seepage of leachate.

Finally, the federal government needs to support and encourage, not necessarily with money, but help all of these new technologies to grow.

Every one of us, every single municipality in this whole country, has a problem with garbage.

I hope that gives you a summary. You can see that I'm kind of passionate about the issue.

The Chair Conservative Harold Albrecht

Absolutely. You're going to have to work on that passion a bit.

We'll move now to our round of questions.

We'll start with the government side, Mr. Carrie.

Colin Carrie Conservative Oshawa, ON

Thanks a lot, Bob, for being here. I remember talking to you, and I remember your passion about this issue, so it's great to have you in front of committee today.

I remember you talking to me about this gasification and Plasco. I am wondering if you could explain a little more about the difference between the incinerators and the gasification plants.

3:40 p.m.

Bob Mills

Hi.

I guess the biggest point really is the temperature. I think the very fact that about 99% of everything that is in garbage....

You know, you've recycled and done all that at the front end. You do that no matter what. Whatever is left is what you now put into the gasification process. By using plasma at 4,000 to 6,000°C, you are destroying everything and turning it into its molecular base. It is then recombined into usable materials. In China, the most interesting part is that they see the water as being one of the most useful materials produced by this process.

An important point is that you have 99% of this never getting out again. You have slag, which can be used for road material, and then you can use scrubbers and so on to handle that 1%.

In an incinerator, you have 30% of waste ash that is left after you finish. That can be used—some in concrete, and so on—but it's very concentrated, bad stuff, so that's a big concern. No matter how good the scrubber is, you do have the release of a number of materials. That's documented all over.

I guess that's the big difference between the two processes. It's a matter of not releasing anything and turning it into a valuable product, and you can do that with almost 99% of garbage.

3:40 p.m.

Conservative

Colin Carrie Conservative Oshawa, ON

I was going to ask you that.

What are the substrates that are left? I thought some was for gypsum. You could use some things for asphalt. They said it could even be nitrogen for fertilizer. What is left when you gasify things?

3:45 p.m.

As an Individual

Bob Mills

Well, remember, you have everything broken down into its chemical base, so by the technology that's involved, you can create pretty much what you want. You do produce nitrogen for fertilizer. You produce CO, which can be burned as a gas and can then power our electricity, provide a lot of electricity.

With the slag, which you've removed all of the heavy metals from and sold those metals, you've removed anything that would be a contaminant and turned it into a usable material. I think that's the big thing.

Also, as I said, for the Chinese, water was the big thing for them, that they can get a source of water. Now nobody is recommending in Canada that we would put that into our domestic water stream. I don't think that would sell too well. However, in other places where there's a big shortage of water, you could certainly use it for agriculture and so on.

It's pretty well everything that can be used that comes out of a full gasification plant.

3:45 p.m.

Conservative

Colin Carrie Conservative Oshawa, ON

Are there any noted health risks with gasification that you know of?

3:45 p.m.

As an Individual

Bob Mills

Well, the Ontario government has done a study of projects like Plasco, and there are other ones that are well along in the development stages, some in the U.S. and in Europe. The analysis shows that in many cases the amounts are undetectable.

I was at some hearings in California, and people said that if they're undetectable, why not say it's zero? Well, an engineer will say it's zero today because we can't detect it, that the instruments today will not detect the mercury coming out or the lead or whatever, but maybe sometime in the future, 20 years from now, somebody will develop a technology to identify these nanoparticles.

You could basically say we'll never do anything because there might be something we don't know. You do need the science, but importantly, you need to know what's going into that garbage, and that's where the regulations and restrictions could be much tighter.

3:45 p.m.

Conservative

Colin Carrie Conservative Oshawa, ON

Would you be able to share with us some more of the success stories from around the world? Who's doing it best? Who would you say has the best practices if we're looking at a country right now?

When I started this, and remember this was in the seventies so it's a long time ago, certainly the Scandinavian countries, Germany, and the Netherlands, but they have been passed by now because the incinerator process was the big deal, and that's what they were perfecting.

I think today you will find a whole bunch...you've heard from witnesses about some plants that are using all kinds of new technologies. I think Canada could easily be a leader and the export potential of that leadership, whether it's Plasco or Enerkem, or whoever it is, if they perfect that technology, the saleability of it to countries like India, China, and Brazil is just tremendous.

The Danes developed the windmill and perfected that and then they made big profits for their country in jobs. I think we could do the same with garbage if we just put our minds to it, but you do need to give provinces and municipalities the confidence that the federal government wants to find a solution. That was lacking in my little case study here in Red Deer in central Alberta. We didn't have strong support. We had no negatives, but no strong support positively to make this happen, so municipalities and provinces didn't have the confidence to go ahead with some of this new technology.

The fear of change is what's so critical here. Everybody says that if we do it like grandpa did it, at least we know what's going to happen. We have to go further than that.

Sorry for the long answer.

Thank you, Mr. Carrie. Your time is up.

I will move now to Mr. Bevington for seven minutes, please.

Mr. Mills, it's nice to see you again. We remember you from your time here.

You didn't talk much about the U.S. and what they do there and how they deal.... It is the second largest economy in the world, close to the first still. What are they doing that we could pick up on?

3:50 p.m.

As an Individual

Bob Mills

If you were to look at U.S. examples—I mentioned the one in Florida and I've been to the ones in New York and Michigan—they're landfilling. They claim they have liners that don't leak, but no engineer will guarantee that. I would say for the most part it's either incinerating or landfilling.

General Electric and Westinghouse have been working with new technologies, but they're really on a very backward scale as far as I'm concerned. I think we could become the leaders here and sell them a lot of this technology.

3:50 p.m.

NDP

Dennis Bevington NDP Northwest Territories, NT

Yes, if they're not there, perhaps we can get there. Is that your point of view?

3:50 p.m.

As an Individual

Bob Mills

I think so, yes.

3:50 p.m.

NDP

Dennis Bevington NDP Northwest Territories, NT

Have you examined federal funding for these types of projects? How does it fit in with other countries? Are we providing proper support to make this type of garbage revolution possible, or are we content to leave it in the hands of the provinces?

3:50 p.m.

As an Individual

Bob Mills

That's passing the buck. The municipalities don't have the money. They're stretched as far as they can go, so they can't do anything. The provinces have other priorities, health care and so on, so I don't think there's enough funding out there.

You can get a lot of private funding. SDTC does a good job with a limited amount of funding. Funds like the carbon tax in Alberta have quite a lot of money that they put into new technologies. A bit is being done, but there could be much more if we want to be world leaders.

3:50 p.m.

NDP

Dennis Bevington NDP Northwest Territories, NT

Have those funds you're talking about participated in any of the development of these new technologies?

3:50 p.m.

As an Individual

Bob Mills

I know they have with Plasco, and I know in Alberta they have with other projects like composting, so I would say yes, but I don't think you'd find any entrepreneur who would say it's enough. More than that, it's the physical support. The feds are behind in finding a solution. I think that's the moral we have to have, and we don't have that.

3:50 p.m.

NDP

Dennis Bevington NDP Northwest Territories, NT

Say you were going to burn garbage to produce electricity, what would the profile be in comparison to, say, coal?

3:50 p.m.

As an Individual

Bob Mills

Again, incineration is not the way to go. Even with modern scrubbers, incineration will pretty much give you the same problems as coal in terms of greenhouse gases, in terms of carcinogenic emissions, dioxins and furans. Again, they're just too low a temperature. You need a high temperature and you need to capture everything. That's the technology that is going to dominate, and unfortunately, or fortunately, the Chinese are really working on that, and I firmly believe—again I've been going to China since 1979—that environmentally 15 years out they are going to become leaders if we don't in this area of garbage.

That's hard to believe but I really believe it.

3:50 p.m.

NDP

Dennis Bevington NDP Northwest Territories, NT

If you're gasifying and you're using the gas to produce something, perhaps electricity, perhaps just simply heat, what's the comparison with the other energy forms right now? Would a carbon tax make the difference there to gasification to bring it on stream quicker to make the economics look better? Of course, garbage has to be a lower.... If you're avoiding landfill, you're avoiding some of the issues that come with methane and those other products in a landfill. What would you say would be required to make gasification producing electricity economically comparable to other forms of energy production?

3:55 p.m.

As an Individual

Bob Mills

At first it's going to be more expensive; I don't think there's any question about that. But you have to think about the whole package: what you're doing to your air, what you're doing to your groundwater, what you're doing to future generations, and the liability question. I think when you put all that package together and you think of the cost of it, and the cost of the carbon, I think you have a reason to say, “Let's get a new technology that releases nothing”. Biogas is basically a lot cleaner than using gasoline, or diesel, or whatever. I think you'd solve your greenhouse gas problem by refining—and that's really what it's all about—refining that garbage into a usable material, a biogas or an energy producer, electricity producer.

3:55 p.m.

NDP

Dennis Bevington NDP Northwest Territories, NT

Are you familiar with the process that they developed in Borlänge, Sweden? They sort the garbage very carefully and then they use sensors to detect anything that slips into their stream in order to provide that assurance that what they're burning is free of products that can create those hazardous components.
