These agricultural wastes may be used alone or in an appropriate combination of two or more. The form of the agricultural waste is not particularly limited, and may be used as it is or after pretreatment such as pulverization.

好ましい。By subjecting these agricultural wastes to explosive or steaming treatment, the amorphous portion is hydrolyzed and the physical structure is destroyed, thereby facilitating composting. In addition, in the case of agricultural waste having a solid structure such as rice husk or buckwheat husk, it is desirable to pulverize after steaming. The explosion treatment in the present invention refers to an operation in which agricultural waste is put into a pressure-resistant container, held at a predetermined pressure in the presence of steam for a predetermined time, and then rapidly released to the atmospheric pressure. At this time, pressurization can be performed by a method using compressed air, a method of externally heating a closed container, a method of introducing high-pressure saturated steam into the container, or the like. The method of introducing is preferred.

The pressure is 9 MPa, preferably 1.0 to 2.9 MPa. If the pressure exceeds the upper limit, substances that inhibit the growth of microorganisms may be generated and accumulated.If the pressure is lower than the lower limit, the hydrogen ion concentration does not increase and hydrolysis of the amorphous portion proceeds. Therefore, the physical structure is not sufficiently destroyed, which is not preferable. The pressurizing time is usually 1 minute to 2 hours, preferably 5 to 60 minutes. The temperature is usually 1

ることにより、堆肥化し易い素材とすることができる。[0010] Next, the steaming treatment in the present invention is to heat and pressurize the agricultural waste in steam or liquid, usually by immersing the agricultural waste in water in a pressure vessel. The processing conditions are the same as the above-mentioned explosion processing, and the pressure is 0.5 to 4.9 MPa, preferably 1.0 to 2.0 in gauge pressure.
The treatment time is usually 1 minute to 2 hours, preferably 5 minutes to 1 hour. After the steaming treatment, if necessary, the material can be easily composted by crushing, for example, crushing with a hammer mill or the like.

に応じて、処理物を水洗あるいは中和する。[0011] The above-mentioned explosion or steaming treatment can be carried out by adding an acid or buffer solution to prepare a material which can be easily composted under milder conditions. As the acid used at this time, for example, mineral acids such as hydrochloric acid, sulfuric acid, nitric acid, and phosphoric acid and organic acids such as acetic acid, lactic acid, citric acid, malic acid, succinic acid, and oxalic acid can be used. Acetic acid is particularly preferred. As the buffer solution, for example, an acetate buffer or a phosphate buffer is used, and an acetate buffer is preferable. These acid or buffer solutions are added so that the hydrogen ion concentration becomes 10 -6 to 10 -1 mol · dm -3 . When an acid or buffer solution is used, the treated product is washed or neutralized as necessary.

することができる。[0012] Explosive or steamed agricultural waste is usually obtained as a slurry, and the treated product is recovered by appropriate solid-liquid separation. Solid-liquid separation may be performed by known means such as squeezing, centrifugation, or filtration alone, or if necessary.
A combination of more than one kind can be applied arbitrarily, and any of a batch type or a continuous type may be used, but a screw press capable of continuously pressing is preferable. Composting can be easily performed by adding an appropriate nutrient to the explosion-treated or steamed product of the agricultural waste obtained as described above. At that time, composting can be carried out by means such as open pile type, rotary kiln type, auger type, multi-stage type, silo type or bottle type. In addition, when composting, useful microorganisms such as aerobic bacteria can be inoculated as seeds, if necessary.

The present invention is not limited by these. Example 1 250 g of uncrushed rice hulls was put into a reaction vessel of a 2 dm 3 volume explosion crusher (manufactured by Tsukishima Kikai), pressurized with a saturated steam pressure of 1.5 MPa gauge pressure for 15 minutes, and then rapidly placed in a receiving tank at atmospheric pressure. Released and exploded. The obtained slurry was resuspended in about 20 times water after centrifugal dehydration, and again centrifuged to remove water by about 5 times.
A 0% one was prepared. Then, air-dry this outdoors,
Finally, a dried product having a water content of about 10% was obtained. The explosion-treated product thus obtained is different in appearance from the raw rice husk, but as shown in Table 1, the water retention is greatly improved, and the water absorption is also about 25%. It has grown.

Then, after adjusting the water content to about 60% (w / w), a commercially available group of useful microorganisms [EM bacteria, manufactured by Shuto) was added to 2% (w / w).
The mixture was added and composted in a horizontal stirring fermenter (internal volume: 100 dm 3 , charge: 50 kg). For comparison, the same treatment was applied to unmilled rice hulls or rice hulls hydrolyzed for compost.

On the other hand, the uncrushed rice hulls and the water crushed rice hulls hardly change even if treated for one month or more.
Composting hardly progressed. Moreover, as is clear from Tables 2 and 3, the explosion-treated product has a remarkable increase in the soluble components in cold water, soluble components in hot water and 1% NaOH, and a decrease in cellulose. And EM bacteria. On the other hand, in the unmilled rice hulls and the water-milled rice hulls, all components showed little change.
