Hello Thin water: Regarding using waste oil.
You are in the industry, wonderful.
I have made a proposal to the national park and the government here. In general it has been well received. I may be getting back to you as there is no existing system in place. Pretty sad to see all of the waste oil just dumped into the street. Do you have any simple literature I can use to back up what I am proposing ? Case studies or any simple to comprehend literature that I can use to present to the government ?
I am sure I can find it, but we simply need to collect all of the waste oil, clean it and burn it in the island generators, too much info will melt their minds. Any similar projects in remote areas that have been proven to work ? I do not need exhaustive studies.
Thanks
Larry
