Part 2: Odaira's Yojigen - Look for more than one product from a single process

Abe V Rotor

In rice milling, rice bran is a by-product used as a main feed component. The idea is, to be able to efficiently use both the principal and its by-products. In Mindanao, pineapple pulp and peelings from the cannery are fermented into vinegar, or fed directly to livestock. In the banana industry, rejects are converted into catsup, or cattle feed. Sugar is fermented into wine, or made into vinegar. The production of nata de coco can be combined with vinegar making, creating a three-stage process wine, vinegar and nata manufacture.

There are enterprises engaged in integrated rice production and piggery. The idea is to make use of the grain by-product for meat production. On a larger scale, there is need for a complex of rice milling, feed milling, storage, and transportation facilities in one location.

Take advantage of any leftovers as a resource for the next process.

The idea behind this concept is the recycling of waste. A biogas digester processes piggery and poultry waste into two products: Cooking gas and sludge used as organic fertilizer. Corn stalks and peanut hay, harvesting leftovers can be fed to livestock as forage. Rice hay may be used as mulch.

Mushroom culture depends largely on the availability of suitable substrates such as rice straw, banana leaves, and sawdust. According to Prof. Odaira, aside from being used as fuel, peat is also a good material for growing mushroom. Peat, after all, is an accumulation of cellulose materials (mainly lignin) spared of decomposition under anaerobic (living, active and occurring in the absence of oxygen) and waterlogged condition. Such material is plentiful in swamps such as the Sab-A Basin in Leyte.

Chicken manure is applied in fishponds to increase algal growth which in turn is forage to milkfish or tilapia.
