How to deal with meal waste?
How to deal with food waste in the diet? Throw away the extra fruit and vegetable skins and vegetable leaves? Throw away unfinished meals? In fact, as long as these kitchen wastes are sorted, recycled, and reused reasonably, and they are fermented into natural organic fertilizers. This not only eliminates the trouble of cleaning the kitchen but also avoids the natural energy consumed by the decomposition of this garbage.
Application of food waste:
Kitchen Waste Food waste is food waste, food waste, food processing waste, non-edible animal and vegetable oils, and various oil-water mixtures from households, schools, canteens, and catering industries. It is a part of urban domestic waste.
The advancement of domestic waste classification, continuous improvement of domestic waste terminal treatment facilities and equipment, standardization of domestic waste collection and transportation, and realization of harmless and resource-recycling energy-based treatment equipment for kitchen waste has attracted more and more attention.
In the early days, these were good things. Every day we could see some dirty and greasy trucks under the night, pulling them away from the restaurant in buckets. Where did you go? Most of them are sent to pig farms and used directly as pig feed.
Then there was a policy that food waste was not allowed to feed pigs directly. After a period of interception, a considerable part of the food waste was sent to the food waste treatment plant. The treatment principle of the food waste treatment plant is basically: deoiling (processing into industrial grease or biodiesel)-controlling moisture and salt content-microbial fermentation (the product is a bio-organic fertilizer raw material with a certain fertilizer efficiency).
How to make fertilizer from food waste?
First of all, clean up the food waste, such as bones and the like should be cleaned out and crushed. Large pieces of food should be cut into pieces.
Then there is the preparation of auxiliary materials. The auxiliary materials can be straw sawn wood, weeds, leaves, fungus residue, crop scraps, etc. These are mainly used to regulate water. Then every ton of material needs to add 20-30% of livestock manure and 10-20 kg of urea.
After the above-mentioned meal waste is mixed with auxiliary materials, livestock and poultry manure, and urea. Adjust the water content to about 50-55%, and then add 400-500 grams of Youjunkang organic fertilizer starter per ton of materials, mix evenly, and then pile and ferment.
Stacked composting can be used, the stacking material is about 1.5 meters high, 2 meters wide, and the length is not limited. The piled material must be loose and breathable, and not agglomerate. You can poke holes in the piled material. Or tank fermentation put the piled material directly into the tank.
Generally, the stack temperature can rise above 60 degrees in 1-2 days. At this time, the first turning is necessary. The stack-type composting needs to be turned by a Compost turner, and the stack temperature will rise every 2 to 3 days. Turn the pile at 60-75 degrees. The whole process will be turned at least 3 times. After about 15 days of fermentation, the waste will become crunchy and black. It will not heat up anymore. The pests and diseases inside will be affected. Be killed. Meal waste becomes a safe and effective organic fertilizer raw material. The organic fertilizer raw material can be used directly or granulated and packaged through the Organic fertilizer production line.
