Message-ID: <[email protected]> Content-Type: text/plain; charset=ISO-8859-1 Dear List, all biochemical reactions are accompanied by a cascade of electrons being transfered through a chain of electron acceptors and donors. I am quite sure that anaerobic digestion is also accompanied by a similar cascade of electrons. An A.D.Plant does not produce any heat, but if such a cascade of electrons occurs in anaerobic digestion, it might be possible to somehow use this electricity.

We'll compile them and put them on the websites while we determine what is most suitable for the particular application in Southern Africa. I have to admit that when I last looked at a pile of orange peels (in Brazil) I wasn't thinking of how they could be used. It certainly looks like at sufficient scale the limonene may be worth recovering. At smaller scales management (rotting) or use (briquetting, drying, charring) of the peel also seems to have potential. Pigs and chickens would also probably recycle the peel, or make enough of a mess to be incorporated in compost or soil. Feeding to birds with char is not high on my list unless there is a health benefit. Usually the object is to increase weight gain my increasing intake rather than reduce intake with a low density material like char.

A total of 120 broilers of Habbard strain at 22 days of age were used in the experiment and were divided into four groups of 30 birds in each. Each group was divided into five replicates with six chicks per replicate. Birds in the experimental groups were fed citrus wood charcoal at rates of 0, 2,4 and 8% of the ration DM in replacement of yellow corn. The results showed that inclusion of citrus wood charcoal at rate of 2% had an effect on body weight gain, feed intake and feed conversion efficiency. The results indicated that the effect of citrus charcoal is an age dependent as it had no effect at ages of more than 29 days. However, inclusion of citrus wood charcoal increased birds abdomen fat. http://www.najah.edu/researches/355.pdf cheers, Erich On Thu, Jun 23, 2011 at 12:47 PM, Tom Miles <[email protected]> wrote: > ** > > > I've had an inquiry from Southern Africa about orange peels.

Seemed that the moldy more so than the fresh which I attributed to some antibiotic production of the mold. I have used citrus in Lombriculture and found despite what literatue told me that worms like them and breed elevated rates when citrus drops are included in coffee pulp as compared to just coffee pulp. I also found this is true for Annona, and Guava drops which I attribute to sugar content.
