Description
本発明は、肉骨粉を有価物として利用可能にした肉骨粉の処理方法に関するものである。 The present invention relates to a method for treating meat-and-bone meal that makes meat-and-bone meal available as a valuable resource.
従来の肉骨粉の処理方法は、平成１３年に日本国内において狂牛病（ＢＳＥ）が発生してから、全ての肉骨粉を一般廃棄物として取り扱うのみであった。具体的には、肉骨粉を焼却して最終処分場に埋めたり、肉骨粉をセメントに混合して処理される等していた。
しかしながら、従来の肉骨粉の処理方法では、肉骨粉を一般廃棄物として処理しているだけであるので、肉骨粉の有価物としての利用が全くなされていなかった。 However, in the conventional meat-and-bone meal processing method, since the meat-and-bone meal is only treated as a general waste, the meat-and-bone meal has not been used as a valuable resource.
そして、肉骨粉を肥料として利用することができれば、肉骨粉の有価物としての利用が可能となるため、肉骨粉の肥料としての利用が強く望まれることとなった。 And if meat-and-bone meal can be used as a fertilizer, it will become possible to use meat-and-bone meal as a valuable material, and therefore use of meat-and-bone meal as a fertilizer has been strongly desired.
そこで、本発明は如上のような従来存した諸事情に鑑み創出されたもので、従来は一般廃棄物として処理していた肉骨粉を、肥料として利用可能にした肉骨粉の処理方法を提供することを目的とする。 Therefore, the present invention was created in view of the existing circumstances as described above, and provides a method for treating meat-and-bone meal in which meat-and-bone meal that has been treated as general waste can be used as fertilizer. For the purpose.
本発明に係る肉骨粉の処理方法においては、牛の特定危険部位を含む牛のみからなる肉骨粉を、単体で空気中の燃焼温度がおよそ１２００℃で燃焼させた骨灰を、肥料として使用することによって、上述した課題を解決した。 In the method for treating meat and bone meal according to the present invention, bone ash obtained by burning meat and bone meal consisting only of a cow containing a specific dangerous part of the cow at a combustion temperature of about 1200 ° C. in the air is used as a fertilizer. The above-described problem has been solved.
以上のように構成された本発明に係る肉骨粉の処理方法において、牛の特定危険部位を含む肉骨粉を単体で、空気中１０００℃〜１３００℃の温度範囲で、このうち好ましくは、およそ１２００℃で焼却することによって、肉骨粉から有害な物質が取り除かれ、肉骨粉から良質な肥料（骨灰）が生成される。 In the meat-and-bone meal processing method according to the present invention configured as described above, the meat-and-bone meal containing a specific dangerous part of cattle alone, in the temperature range of 1000 ° C. to 1300 ° C. in air, preferably about 1200 Incineration at ℃ removes harmful substances from meat-and-bone meal and produces high-quality fertilizer (bone ash) from meat-and-bone meal.
本発明は以上のように構成されているため、従来は一般廃棄物として処理していた肉骨粉を、肥料として有効に利用することができる。 Since this invention is comprised as mentioned above, the meat-and-bone meal conventionally processed as a general waste can be utilized effectively as a fertilizer.
すなわち、１０００℃〜１３００℃の燃焼温度で肉骨粉を燃焼処理したときには、窒素全量（Ｎ）が減少し、リン酸全量（Ｐ２Ｏ５）が増加することとなり、肉骨粉から良質な肥料（骨灰）を得ることができる。 That is, when meat-and-bone meal is burned at a combustion temperature of 1000 ° C. to 1300 ° C., the total amount of nitrogen (N) decreases and the total amount of phosphoric acid (P 2 O 5 ) increases. Bone ash) can be obtained.
特に、およそ１２００℃の燃焼温度で肉骨粉を燃焼処理したときに、窒素全量（Ｎ）が最も減少し、リン酸全量（Ｐ２Ｏ５）が大幅に増加する事実が判明している。 In particular, it has been found that when meat-and-bone meal is burned at a combustion temperature of about 1200 ° C., the total amount of nitrogen (N) is the smallest and the total amount of phosphoric acid (P 2 O 5 ) is greatly increased.
また、およそ１２００℃の燃焼温度で肉骨粉を燃焼処理したときには、狂牛病（ＢＳＥ）の要因となる遊離アミノ酸組成物が全く存在しなくなり、肉骨粉から極めて安全な肥料（骨灰）を得ることができる。 In addition, when meat and bone meal is burned at a combustion temperature of approximately 1200 ° C., there is no free amino acid composition that causes mad cow disease (BSE), and extremely safe fertilizer (bone ash) is obtained from meat and bone meal. Can do.
尚、およそ８００℃以上の燃焼温度で肉骨粉を燃焼処理したときにも、狂牛病（ＢＳＥ）の要因となる遊離アミノ酸組成物が全く存在しなくなる事実が判明している。 It has been found that even when meat-and-bone meal is burned at a burning temperature of about 800 ° C. or higher, there is no free amino acid composition that causes mad cow disease (BSE).
一方、所定の燃焼温度で処理した肉骨粉を肥料として水稲の田に使用すると、稲の茎が丈夫になり、大風・豪雨・日照り等の自然災害に対して非常に強い耐性を備えた稲を栽培できる。 On the other hand, when meat-and-bone meal processed at a prescribed combustion temperature is used as a fertilizer in paddy rice fields, the rice stalks become strong, and the rice has extremely strong resistance to natural disasters such as heavy winds, heavy rain, and sunlight. Can be cultivated.
また、稲の実の部分の殻も強くなって、大きな米の収穫が可能となり、米の収穫量を大幅に増やすことができる。 In addition, the husks of the rice seeds are strengthened, allowing large rice to be harvested and greatly increasing the amount of rice harvested.
しかも、米自体に張りが生じて、米が非常に美味しくなる。 In addition, the rice itself becomes stretched and the rice becomes very delicious.
この他、田における種々の農作物の肥料として燃焼処理した肉骨粉を使用したときにも、様々な優れた効果を発揮するものである。 In addition, when meat-and-bone meal combusted as a fertilizer for various crops in the rice field is used, various excellent effects are exhibited.
以下に、本発明を実施するための最良の形態を説明する。 The best mode for carrying out the present invention will be described below.
本発明に係る肉骨粉の処理方法で処理する肉骨粉は、日本国内で制定された肥料取締法の骨灰の定義に基づき、例えば、蛋白プリオンが病巣といわれる狂牛病に冒された牛の特定危険部位を含む肉骨粉を、他のものと混合せずに単体で使用する。 The meat-and-bone meal to be treated by the method for treating meat-and-bone meal according to the present invention is based on the definition of bone ash in the Fertilizer Control Law established in Japan, for example, the identification of cattle affected by mad cow disease in which protein prions are referred to as foci Use meat-and-bone meal containing dangerous parts alone without mixing with other ingredients.
具体的には、牛の肉骨粉を、空気中１０００℃〜１３００℃の温度範囲で、特に好ましくは、およそ１２００℃近傍の温度で燃焼させる。このとき、燃焼時間が長くなるほど骨は脱水し、含有物の油分や炭化物等が灰化し、骨に含有される全リン酸成分が高まるものとなって、良質な肥料（骨灰）が生成される。 Specifically, beef meat-and-bone meal is burned in air at a temperature range of 1000 ° C. to 1300 ° C., particularly preferably at a temperature around 1200 ° C. At this time, the longer the burning time, the more the bone is dehydrated, the oil content, carbides, etc. of the contained material are ashed, and the total phosphoric acid component contained in the bone is increased, producing a high-quality fertilizer (bone ash). .
次に、上述した方法により生成された肥料（骨灰）の分析・試験結果について説明する。 Next, analysis and test results of fertilizer (bone ash) generated by the above-described method will be described.
先ず、１０００℃近傍の温度で肉骨粉を燃焼させた場合の肉骨粉焼却灰の分析・試験結果は、下記の表１に示す通り、窒素全量（Ｎ）が０．１７％、リン酸全量（Ｐ２Ｏ５）が２０．１３％、く溶性リン酸（Ｐ２Ｏ５）が１８．７６％、加里全量（Ｋ２Ｏ）が０．８３％、石灰全量（ＣａＯ）が２９．４８％となる。 First, as shown in Table 1 below, the analysis and test results of meat-and-bone meal incinerated ash when meat-and-bone meal was burned at a temperature in the vicinity of 1000 ° C. showed that the total amount of nitrogen (N) was 0.17%, the total amount of phosphoric acid ( P 2 O 5 ) is 20.31%, soluble phosphoric acid (P 2 O 5 ) is 18.76%, total potassium (K 2 O) is 0.83%, and total lime (CaO) is 29.48%. It becomes.
また、１２００℃近傍の温度で肉骨粉を燃焼させた場合の肉骨粉焼却灰の分析・試験結果は、下記の表２に示す通り、窒素全量（Ｎ）が０．０２％、リン酸全量（Ｐ２Ｏ５）が３３．６３％、く溶性リン酸（Ｐ２Ｏ５）が２８．７５％、加里全量（Ｋ２Ｏ）が１．０８％、石灰全量（ＣａＯ）が４８．７９％となる。 In addition, as shown in Table 2 below, the analysis and test results of meat-and-bone meal incinerated ash when meat-and-bone meal was burned at a temperature in the vicinity of 1200 ° C showed that the total amount of nitrogen (N) was 0.02% and the total amount of phosphoric acid ( P 2 O 5 ) 33.63%, soluble phosphoric acid (P 2 O 5 ) 28.75%, total potassium (K 2 O) 1.08%, total lime (CaO) 48.79% It becomes.
このとき、１０００℃近傍の温度で燃焼させた場合よりも窒素全量（Ｎ）が減少し、リン酸全量（Ｐ２Ｏ５）が増加している。その結果、肉骨粉を１２００℃近傍の温度で燃焼させるのが、良質な肥料（骨灰）を得るための最適条件となることが判明した。 At this time, the total amount of nitrogen (N) is decreased and the total amount of phosphoric acid (P 2 O 5 ) is increased as compared with the case of burning at a temperature near 1000 ° C. As a result, it was found that burning meat-and-bone meal at a temperature in the vicinity of 1200 ° C. is the optimum condition for obtaining a high-quality fertilizer (bone ash).
また、１２００℃（空気中…雷神処理）の温度で肉骨粉を焼却させた場合の肉骨粉焼却灰の分析・試験結果では、下記の表３に示す通り、窒素が０ｇ／１００ｇ（ケルダール法による分析）、リンが１７００ｍｇ／１００ｇ（比色法による分析）、カリウムが９６０ｍｇ／１００ｇ（原子吸光光度法による分析）、カルシウムが３１０００ｍｇ／１００ｇ（原子吸光光度法による分析）となった。 In addition, according to the analysis and test results of the meat and bone powder incineration ash when the meat and bone powder was incinerated at a temperature of 1200 ° C. (in the air ... thunder god treatment), as shown in Table 3 below, nitrogen was 0 g / 100 g (according to the Kjeldahl method). Analysis), phosphorous was 1700 mg / 100 g (analysis by colorimetric method), potassium was 960 mg / 100 g (analysis by atomic absorption photometry), and calcium was 31000 mg / 100 g (analysis by atomic absorption photometry).
この他、下記の表４に示す通り、１２００℃近傍の温度で燃焼させた場合の肉骨粉焼却灰のアミノ酸分析計（検出限界１ｍｇ／１００ｇ）による分析結果としては、例えば、イソロイシン、ロイシン、リジン、メチオニン、シスチン、フェニルアラニン、チロシン、スレオニン、トリプトファン、バリン、アルギニン、ヒスチジン、アラニン、アスパラギン酸、グルタミン酸、グリシン、プロリン、セリン等の遊離アミノ酸組成物（ｍｇ／１００ｇ）は、全て検出されなかった。 In addition, as shown in Table 4 below, analysis results of amino acid analyzer (detection limit 1 mg / 100 g) of meat-and-bone meal incinerated ash when burned at a temperature near 1200 ° C. include, for example, isoleucine, leucine, lysine , Free amino acid compositions (mg / 100 g) such as methionine, cystine, phenylalanine, tyrosine, threonine, tryptophan, valine, arginine, histidine, alanine, aspartic acid, glutamic acid, glycine, proline and serine were not detected.
このように、肉骨粉を１２００℃近傍の温度で燃焼させると、狂牛病（ＢＳＥ）の要因となる遊離アミノ酸組成物が全く存在しなくなり、極めて安全な肥料（骨灰）を得ることができる。 Thus, when meat-and-bone meal is burned at a temperature in the vicinity of 1200 ° C., there is no free amino acid composition that causes mad cow disease (BSE), and extremely safe fertilizer (bone ash) can be obtained.
本発明に係る肉骨粉の処理方法によって生成された肥料（骨灰）を、例えば、農作物の育成等に利用すると、極めて良質な農作物を栽培し、これを出荷できる。そのため、肉骨粉の燃焼処理により生成された肥料（骨灰）は、農作業者や農協等の様々な農業関係者に広く利用されるものである。 If the fertilizer (bone ash) produced | generated by the processing method of the meat-and-bone meal based on this invention is utilized for the cultivation etc. of crops, for example, very good quality crops can be cultivated and this can be shipped. Therefore, the fertilizer (bone ash) produced | generated by the combustion process of meat-and-bone meal is utilized widely by various agricultural persons, such as a farm worker and an agricultural cooperative.
