Also used as
この家畜用敷材は、牛や豚などの家畜の畜舎の床に敷き詰められて使用される。そして、家畜用敷材は、炭化したコーヒーかすが消臭剤や糞尿の吸収剤として機能するとともに、粉末状の卵殻が中和剤や糞尿の凝集剤として機能し、炭化した茶かすが殺菌剤として機能する。そのため、家畜の畜舎を衛生的に維持することができる。 The livestock covering material is used by being laid on the floor of a livestock barn such as cattle or pigs. And for livestock bedding, the carbonized coffee grounds function as a deodorant and fecal urine absorbent, the powdered eggshell functions as a neutralizing agent and an excrement coagulant, and the carbonized tea grounds function as a disinfectant To do. Therefore, the livestock barn can be maintained in a sanitary manner.
この家畜用敷材は、使用中に家畜の糞尿が混合するが、そのまま回収して、土壌改良材の原料として有効利用することができる。 This livestock bedding mixes livestock manure during use, but can be recovered as it is and effectively used as a raw material for soil amendments.
すなわち、使用により家畜の糞尿を吸収した家畜用敷材を乾燥する乾燥処理を行い、それをそのまま袋詰めなどして土壌改良材として使用できる。なお、乾燥処理は、高温加熱による乾燥でもよく、天日干しなどによる自然乾燥でもよい。また、乾燥後は、再び家畜用敷材としても使用することができ、複数回家畜用敷材として使用した後に土壌改良材として使用することもできる。 That is, it can be used as a soil conditioner by performing a drying process for drying livestock bedding that has absorbed the excrement of livestock, and then packing it as it is. The drying treatment may be drying by high temperature heating or natural drying such as sun drying. Moreover, after drying, it can be used again as a livestock bedding material, and can also be used as a soil improvement material after being used as a livestock bedding material multiple times.
以上に説明したように、本発明に係る土壌改良材では、従来廃棄物として処分されていたコーヒーかすや卵殻や茶かすを有効に循環して再利用することができる。 As explained above, with the soil improvement material according to the present invention, coffee grounds, eggshells and tea grounds that have been disposed of as waste can be effectively circulated and reused.
また、本発明に係る土壌改良材では、コーヒーかすを脱水後に炭化して使用している。そのため、コーヒーかすの重量を軽減することができ容易かつ安価に運搬することができる。また、炭化によりコーヒーかすの比表面積を約200m2／gにまで増大させることができ、通気性、吸水性、消臭性に優れた土壌改良材とすることができる。 Moreover, in the soil improvement material which concerns on this invention, the coffee grounds are carbonized and used after dehydration. Therefore, the weight of the coffee grounds can be reduced and can be transported easily and inexpensively. Moreover, the specific surface area of the coffee grounds can be increased to about 200 m 2 / g by carbonization, and a soil improvement material excellent in air permeability, water absorption, and deodorization can be obtained.
しかも、本発明に係る土壌改良材では、炭化したコーヒーかすに粉末状の卵殻を混合しているために、卵殻の主成分であるカルシウムによる中和剤や凝集剤としての機能を発揮する土壌改良材とすることができる。また、混合により粉末状の卵殻が炭化したコーヒーかすの細孔に含有されるので、体積当りの重量を軽減することができ、これによっても運搬を容易かつ安価なものとすることができる。 Moreover, in the soil improvement material according to the present invention, since the powdered eggshell is mixed with the carbonized coffee grounds, the soil improvement that functions as a neutralizing agent or a flocculant by calcium, which is the main component of the eggshell.
