Energy Opportunities

We compliment Adam Chamberlain for views expressed in his article “Energy Opportunities” (see Final Analysis in the June/July 2002 edition). We endorse the conversion of landfill gas to electricity but remind Solid Waste & Recycling readers that the gas capture potential of this technology is less than 50 per cent over the full life-cycle of the landfill.

In contrast, energy-from-waste technology relies on advanced combustion technology and can capture 100 per cent of the potential energy and is environmentally clean. Energy-from-waste facilities (or if you prefer resource recovery facilities) are demonstrating their ability to economically provide reliable green energy in over 2000 installations worldwide. The technology is proven and mature, certainly not speculative in nature. Invariably you will find that the critics of high-temperature incineration have not visited a plant incorporating the latest furnace and emission control technologies.

Energy-from-waste is, by a wide margin, the most significant energy opportunity for the Canadian waste management industry.

Tim Hortons cleanup initiative

I’m writing in response to the news item (in the June/July 2002 edition) about the Tim Hortons cleanup initiative. When this announcement first came out with some fanfare in the local newspaper on April 23 I was quite excited and wanted to get involved. I called the local owner of the outlet in my area and left a voicemail identifying myself and offering to help. I also called the local office and left a voice mail there. In addition, I e-mailed a Tim Hortons/Wendy’s address and sent a letter by snail mail commending them for their efforts and offering to help with the cleanup. I have not received any response from anyone (as of press time).

I would think that if they were really committed to this issue they would jump at the chance to have as many people involved as possible. Also, in Pictou County the program date was delayed.

I really hope I’m wrong, but I find myself doubting their motives.

Single-Stream Recycling

I read with great interest Bob Marshall’s article in the April/May edition entitled “Single-Stream Recycling.” Mr. Marshall points out that “it’s important to remember that traditional multi-stream processes do not guarantee better quality because they are only as good as their curbside sort and the separation system within the recycling truck.” I cannot agree more.

It is important that the buyer understand the importance of individual item separation and the body design, which has tremendous importance. I constantly speak with people in our industry that are not aware that there are manufacturers that design recycling bodies that can accommodate up to 12 separate items without cross contamination.

There is some misinformation floating around that recycling bodies must be single stream collection and sorters/pickers are needed because curbside separation is not efficient. Not true. There are many communities that use curbside separation with great success and are very profitable too. One such community is Fayetteville, Arkansas where they have a model program, separating at the curb over 12 items. There are manufacturers that will custom make bodies to meet the individual needs of communities. As with any other product, an educated recycling equipment consumer is a manufacturers best customer.
