For the past 18 months engineers have been testing coal, petroleum coke (a refining by-product) and other fuels in the plant, tinkering with the catalyst and gathering data.
In my case, it began with a well-researched and supervised seven-day fruit and vegetable juice cleanse (during which time I weaned myself off caffeine), followed by an entirely plant-based nutrition program -- an animal-product-free regimen I have adhered to ever since.
