They define green waste as anything fresh and the manures are mentioned in the article. Sewage sludge has undergone bacterial treatment in either aerobic or anaerobic methods. There seems to be something about it BSF do not like. In over ten years of employment and our city Waste Water facility, I have never noticed BSFL in any of the sludge drying beds or in the plant processes though they are numerous in my on site worm beds where fresh organics are added and in our city sanitation truck during the summer months, undoubtedly from weekly dumping of residential and business dumpsters.
Now I am knowing of the BSFL and bin technology used to keep them and have thought to try some of the processed sludge as it becomes available from our new facility's sludge press. It will be a few months before this new facility produces enough sludge in quantities to activate the press but I will give it a try anyway regardless of the article studies.
Composting worms are well known to process sewage sludge and BSFL waste excrements to a further usable product of worm castings so it seems a multi tier continuous flow design of bin with BSFL on top to handle fresh organics with their wastes able to screen onto the lower worm bin, both green wastes and sewage sludge could be processed at the same location and result in worm castings. The liquid from the top BSFL bin would likely be perfect to maintain the moisture in the lower worm bin.
My brain is reeling from the possibilities
Edited to add...As indicated in the ESR Power Point slideshow, the acceptance of BSFL technology by "spoiled" countries and restaurants like you mention due to health department regs is likely to be a major stumbling block for any wide spread use of this technology. It's too bad some buerocratic red tape would prevent such great things to happen. The very use of BSFL to process fresh human waste solids would negate the need for conventional waste treatment facilities like where I work but then you're looking at too many people losing their jobs and a long accepted system of waste treatment simply going away and you know that ain't gonna happen in the US! It was hard enough to get EPA approval just for a pilot project of using composting worms for biosolid conversion and that had to be approved by a resident engineer! We are truly a spoiled nation but I wouldn't want to live anywhere else so am as spoiled I'm afraid...
