Bio-diesel and bio-gas production from seafood processing by-products

Pomegranate by-products (peel and seed) contain about 40-45 percent of the fruit’s weight. The rind of the fruit (peel),when dried, is brown outside, yellow inside, hard, dry, brittle, in irregular fragments, inodorous, and with a very astringent, somewhat bitter taste. Analysis of pomegranate peel (PP) is shown that it contains 18.8 percent of tannin, 17.1 of mucilage, 10.8 of extractive matter, 30 of lignin, a trace of resin, and 29.9 of moisture. However, little information is available on PP nutritive value for ruminants. It is poor in protein and rich in tannins. Tannins components of the peel prevents its optimal use. The objective of this experiment was to evaluate the effect of different levels of urea (U) on in vitro gas production with and without added polyvinylpolypyrrolidone (PVP) to ensiled pomegranate peel (EPP).

By Products

The amount of by-product feedstuffs generally increases as the human population increases and economies grow. Large quantities of by-products are used in the ruminant’s diet in agro-industrial areas. (Gasa, et al. 1989). However, little is known about their fermentation pattern in the rumen and a better understanding of their digestion and products of fermentation is necessary in order to properly balance their introduction into the diets and the knowledge about their potential feeding value is insufficient.
