Yes. I can add that the process was quite elaborate in the sense that first we determined if P3 was the right method. Then we did an international search to narrow down teams and we had over 10 responses, pretty much from Asia, Europe, North America, and Canada. Then the process went down to three main proponents that had the best business case as a team. Then there was the final selection, and as the mayor mentioned, now they're building the facility. The project includes them, basically.
The city contributes per tonne of organic waste it delivers and then the project guarantees a certain amount of gas coming back to us to offset the cost that we've paid for the tipping fee. Essentially, as the mayor mentioned, the gas is then used for the garbage trucks collecting the waste. We are already collecting all that waste, so we've established this as an area where the city took a risk for the private sector, where we guarantee the actual feedstock.
Two years ago we started getting our population ready to provide the feedstock, so the private sector doesn't have that risk, which is a risk that's easy for us to take, so that further reduces the cost of the project.
Now that we have closed on the project and we've selected the technology, we know we're going to have enough gas not only to fuel our garbage trucks that are collecting the waste.... That was an integral part, by the way, of getting citizens to understand what we were doing with the organic waste. When we rolled out the program a year and a half ago we reduced our garbage tonnage by half in the city of Surrey within two month's time. That was because there was a good understanding from the public that we are now adding value to something that was seen as waste before. This was valuable to the city, so everyone contributed.
The last component, which is quite exciting, is that with our district energy now in the city centre we're looking to use the excess gas, which is pure, clean gas, and carbon free, to help heat all our high-rises in our downtown.
