The ConAgra plant in Carthage, MO is either shut down or is in very limited production, and the cost of the end product is much higher than originally estimated.
One major problem - a horrendous odor.

the problem was more than just the odor. that will be fixed. the problem is that the US government did not ban meat products from animal food supplies. the plant was built on the assumption that because of mad cow disease the government would disallow meat products from animal feed. that didn't happen so now they have to buy the turkey offals for the same price that feed producers buy it for. the second thing that didn't happen that was susposed to happen was that the government was susposed to give them tax credits. as a result, in order to make a profit oil has to be up around $80@ barrel.
changing world technologies as a result will open a bunch of plants in europe where they can get better tax breaks--and the meat byproducts are banned so they can get the feed stock free.
