Description

【0001】
【発明の属する技術分野】
本発明は、原料のすべてが産業廃棄物あるいはリサイクル品から作られる農園芸資材、中でも用土や土壌改良材の販売方法に関するものである。更に詳しくは、上水または工業用水を製造する過程で発生する浄水排泥や工業用水排泥、土木工事で発生する不要な土砂、紙パルプを製造する過程で発生する製紙スラッジ、及び肉牛、乳牛、豚、鶏等を飼育する際に発生する家畜糞尿等の各種廃棄物を効率的に再利用する技術に関する。
【0002】
特に、原価構成上、輸送費の占める割合が高い用土や土壌改良材の販売方法において、環境問題解決への取り組みに賛同が得られる法人、個人を広告主とすることで、無料あるいは安価で広範囲に配布する販売方法に関する。
【0003】
【従来の技術】
近年、主に一般家庭より出される一般廃棄物や事業所から出される産業廃棄物の量は増加の一途をたどり、その処分方法をめぐり、環境や人体に与える影響が問題視されている。
【0004】
一般に、浄水排泥や工業用水排泥は多量の水に懸濁した状態で排出されるため、適当な薬品を添加して凝集、脱水後、多くは埋め立て処分されている。建設発生土は、水分含有量が多い場合には固化剤等を付加して脱水後、水分含有量が少ない場合にはそのまま埋め立て処分されている。また、紙パルプ製造工程より排出される製紙スラッジはパルプ繊維や填料、デンプン等の製紙原料からなり、凝集、脱水後、多くは焼却処分されている。さらに、牛、豚、鶏等を飼育する畜産業から排出される家畜糞尿の一部は堆肥や肥料として利用されているものの、大部分については有効な処分方法が無く、素堀や野積みによる処分が問題になっているのが現状である。
【0005】
これら排泥、建設発生土、製紙スラッジ、家畜糞尿はいずれも産業廃棄物であり、処分には多大な経費を要すると共に、最終処分場の用地不足や焼却施設の不備等によるダイオキシンの発生、不完全な処分による環境汚染の懸念等が深刻な問題となっている。
【0006】
農園芸資材、特に1〜数10Lの用土や土壌改良材の販売では、スーパー・ホームセンター・園芸店・農協等において、製品情報のみが印刷された高分子フィルム製の袋に入れられて、販売されている。また、この袋等の包装材料は、意匠性や見た目を気にしたり、あるいはコストを意識した場合、リサイクル品を使うことは必ずしも効果的でない場合がある。
【0007】
一般に、農業、園芸の分野において、鉢植えや苗床用に用いられる用土類や、農地に混合される土壌改良材には土壌や鉱物、ピートモス等が大量に用いられている。これらの多くは、本発明が考案しようとしている産業廃棄物の有効利用によるものではなく、天然の資源を採取あるいは採掘して利用している場合が多い。
【0008】
天然の土は、主に山林等から採取されているが、これに伴う環境破壊が問題となっている。また土壌表層付近の良質な山土を大量に入手することは困難であり、必ずしも植物の生育には適さない土を、土壌改良するなどして手間と時間をかけて利用している例が多い。また、ピートモスの多くは北米及び北欧で採掘、輸入されており、多大なエネルギーをかけて輸送されているのが実状である。
【0009】
本来浄水排泥や工業用水排泥、建設発生土は山林や緑地、田畑等の土壌に由来するものであり、再び自然環境中に還元しうるものとの考えから、植物の培養土等として再利用する試みがなされている。その際、排泥や建設発生土を植物の生育に適した状態にする必要がある。中でも、水に懸濁した状態の浄水排泥や工業用水排泥、建設発生土を、適当な水分率まで脱水、乾燥することが重要である。一般的な加圧脱水装置等を用いた場合、土壌鉱物からなる粘土やシルトを含んだ排泥では、目詰まりや濾砕の形成等が原因で脱水が非常に困難となるため、遠心脱水装置等の限られた装置でしか脱水ができない。そのため、設備費用が莫大となり、最終製品としても高価なものとならざるを得ない。
【0010】
このような状況下において、特開平5−207816号公報には、脱水後粒状に粉砕した高水分の浄水ケーキに低水分のバーク等有機質素材を添加して浄水ケーキの水分を低下させ、さらに動植物性有機肥料を添加、混合して発酵させたぼかし培養土の製造方法が開示されているが、粒状に粉砕するための加工装置やエネルギーが必要となる他、浄水ケーキの水分調整のために、水分を予め調整した有機質素材が必要となり、実現するためには多くの制約が課せられてしまう。
【0011】
特開平9−195278号公報には、下水処理の際に発生する汚泥をコンポスト化し、緑化基材として用いることが開示されているが、下水汚泥コンポストは有機物の割合が高い点を利用して、従来の有機質緑化基盤材に改良資材として一部添加する方法で使用されており、多量の塩類を蓄積していることなどから、下水汚泥コンポストのみで培養土を形成させることは極めて困難である。
【0012】
これらの公報は、製造方法に関するものであるが、いずれにおいても本発明が目的とする産業廃棄物の著しい減少とはなりえていないのが実状である。
【0013】
一方、従来から景品・特典等を使った商品あるいは商品自体に広告を付記する販売方法は広く普及している。しかしながら、本発明のごとく、環境問題を重視すべくその多くを産業廃棄物あるいはリサイクル品から製造することを特徴とした農園芸資材において、それらを充填する袋に広告を付加し費用を回収することで、農園芸資材自体を無料あるいは安価に配布する販売方法はいまだ開示されていない。
【0014】
【発明が解決しようとする課題】
本発明の目的は、上記実状を鑑みたものであって、排泥、建設発生土、製紙スラッジ、家畜糞尿といった産業廃棄物を再利用するにあたり、再処理費用、製品品質、販売価格との関係が、製品を円滑に広く流通させるのに経済的に妥当なものとなるシステムを構築することにある。
【0015】
【課題を解決するための手段】
上記課題を解決するため検討した結果、製造方法からのみ検討していたのでは、これらの多大なる量の産業廃棄物を削減することが困難であることが分かった。そこで鋭意検討した結果、本発明者の主旨に賛同する法人、個人が広告主となることで高品質製品を製造するための再処理費用を回収し、天然の土や各種資源を使用しない廃棄物を原料とした用土や土壌改良材を、無料あるいは安価に配布することで解決できることを見出した。
【0016】
農園芸資材を用いる農家ばかりでなく、一般消費者にも本発明者の主旨に対して理解が得られ、しかも無料あるいは非常に安価で資材が入手可能となれば、従来では想像出来なかった程大量の産業廃棄物が有価物となり、有効利用されることは自明である。
【0017】
本発明における排泥とは、河川や湖沼等から取水した土砂や土壌、浮遊物質等の固形物が混入した水から、飲料水や工業用水を製造する際に除去されるこれらの固形物と水との混合物であり、その含水率は一般に80〜99.9重量%である。

【0023】
本発明における畜産廃棄物とは、養牛、養豚、養鶏業等を営む農場において排出される牛糞尿や豚糞尿、鶏糞といった家畜糞尿を主体とした廃棄物である。これらの家畜糞尿は窒素分を含む易分解性の有機物を含有し、畜産廃棄物の量を調節することで、温度上昇を伴う、原料の急速な発酵を促進する。また、植物の生育を促進する窒素、リン、カリなどの肥料成分を含有し、植物の生育促進効果を有する用土や土壌改良材を製造することが可能である。
【0024】
本発明におけるリサイクルフィルムとは、使用済みプラスチックから再生されたプラスチックよりなるフィルムで、一旦溶融されて再生されるものの他、使用済みの袋を洗浄するなどしてそのまま使用するものも含まれる。プラスチックとしてはポリエチレン、ポリプロピレン、ポリエチレンテレフタレート、ポリ塩化ビニル等が挙げられる。
【0025】
【発明の実施の形態】
本発明に用いられる排泥とは浄水または工業用水を製造する際に河川や湖沼等の水から分離された固形物と水との混合物であり、例えば浄水場や製紙工場で発生する産業廃棄物である。
【0026】
本発明に用いられる建設発生土とは、例えば、トンネルの掘削、山林や原野の造成等の土木工事により発生する土砂である。水分70%以下で、粘土、シルト、砂が適度に存在するものが好ましいが、脱水や篩い分け等により、目的に応じた性状とした後に使用することも可能である。
【0027】

【0028】
本発明に用いられる製紙スラッジとは製紙工程において排出される、スラッジ状懸濁液であり、固形分の90%以上は製紙原料に由来する。中でもパルプ繊維の含有率が高く、このパルプ繊維が脱水助剤となると共に、発酵の際の炭素源として微生物に資化される。このような製紙スラッジとしてパルプ精選工程におけるスクリーンリジェクト、クリーナーリジェクトや抄紙工程における白水等が挙げられる。
【0029】
本発明に用いられる畜産廃棄物とは、畜産業を営む施設において排出される主に家畜の糞尿からなる廃棄物であり、この様なものとして、牛糞尿、豚糞尿、鶏糞等が挙げられる。本発明における培養土や緑化基盤材の原料として用いる場合には、家畜糞尿単独でも使用可能だが、畜産農家での飼育方法に応じ、敷きわら等と混合された状態であってもよい。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a method for selling agricultural and horticultural materials in which all of the raw materials are made from industrial wastes or recycled products, particularly, soil and soil improvement materials. More specifically, purified and industrial water sludge generated in the process of producing tap water or industrial water, unnecessary earth and sand generated in civil engineering work, papermaking sludge generated in the process of producing paper pulp, and beef cattle, dairy cattle The present invention relates to a technology for efficiently reusing various wastes such as livestock manure generated when breeding pigs, chickens, and the like.
[0002]
In particular, in the method of selling land and soil improvement materials, which account for a high proportion of transportation costs due to the cost structure, advertisers can use corporations and individuals who have obtained support for solving environmental problems, and are free or inexpensive. Related to the sales method to distribute.
[0003]
[Prior art]
2. Description of the Related Art In recent years, the amount of general waste mainly from general households and industrial waste from business establishments has been steadily increasing, and the impact on the environment and the human body of the disposal method has been regarded as a problem.
[0004]
Generally, purified water sludge and industrial water sludge are discharged in a state of being suspended in a large amount of water. Therefore, most of them are added to a suitable chemical, coagulated, dehydrated, and then disposed of in landfill. The soil generated from construction is dewatered by adding a solidifying agent or the like when the water content is high, and is landfilled as it is when the water content is low. Further, papermaking sludge discharged from the paper pulp manufacturing process is made of papermaking raw materials such as pulp fiber, filler, starch, etc., and after coagulation and dehydration, many are incinerated. Furthermore, although some of the livestock manure discharged from the livestock industry that breeds cattle, pigs, chickens, etc. is used as compost and fertilizer, most do not have an effective disposal method, and At present, disposal is a problem.
[0005]
These wastewater, construction soil, papermaking sludge, and livestock manure are all industrial wastes, which require enormous costs for disposal, as well as the generation of dioxins due to shortage of land at final disposal sites and inadequate incineration facilities. Concerns over environmental pollution due to complete disposal have become a serious problem.
[0006]
In the sale of agricultural and horticultural materials, especially 1 to several tens of liters of soil and soil improvement materials, supermarkets, home improvement centers, horticultural stores, agricultural cooperatives, etc. are sold in polymer film bags with only product information printed on them. ing. Also, in the case of packaging materials such as bags, it is not always effective to use recycled products when the design property and appearance are concerned or the cost is conscious.
[0007]
Generally, in the fields of agriculture and horticulture, soil, minerals, peat moss, and the like are used in large amounts for soil used for pot planting and nursery and soil improvement materials mixed with farmland. Most of these are not due to the effective use of industrial wastes that the present invention is trying to devise, but often utilize natural resources by extracting or mining them.
[0008]
Natural soil is mainly collected from forests and the like, and the resulting environmental destruction has become a problem. In addition, it is difficult to obtain a large amount of high-quality mountain soil near the surface of the soil, and in many cases, soil that is not necessarily suitable for plant growth is used for labor and time by improving the soil. . Most peat moss is mined and imported in North America and Northern Europe, and is transported with a great deal of energy.
[0009]
Originally, purified water sludge, industrial water sludge, and soil generated from construction are derived from soil such as forests, green lands, and fields, and can be returned to the natural environment. Attempts have been made to use it. At that time, it is necessary to make sludge and soil generated from construction suitable for plant growth. Above all, it is important to dehydrate and dry purified water and industrial water and suspended soil from water suspended in water to an appropriate moisture content. When a general pressurized dehydrator is used, dewatering of clay or silt made of soil minerals becomes extremely difficult due to clogging and formation of filtration. Dehydration can be performed only with a limited device such as. For this reason, the equipment cost is enormous, and the final product must be expensive.
[0010]
Under such circumstances, Japanese Patent Application Laid-Open No. Hei 5-207816 discloses that an organic material such as bark having a low moisture content is added to a high-moisture purified water cake which has been dewatered and pulverized into granules to lower the moisture content of the purified water cake. Addition of organic fertilizer, the manufacturing method of the blurred culture soil fermented by mixing is disclosed, but in addition to processing equipment and energy for crushing into granules, for water adjustment of water purification cake, An organic material whose water content is adjusted in advance is required, and many restrictions are imposed to realize the material.
[0011]
Japanese Patent Application Laid-Open No. 9-195278 discloses that sludge generated during sewage treatment is composted and used as a greening substrate, but sewage sludge compost utilizes a high ratio of organic substances, It is used in a method of adding a part of a conventional organic revegetation base material as an improving material and accumulates a large amount of salts. Therefore, it is extremely difficult to form a culture soil using only sewage sludge compost.
[0012]
These gazettes relate to production methods, but in any case, the present invention has not been able to achieve the remarkable reduction of industrial waste.
[0013]
On the other hand, a sales method of adding an advertisement to a product using a prize, a privilege, or the like or a product itself has been widely used. However, as in the present invention, in agricultural and horticultural materials characterized in that most of them are manufactured from industrial waste or recycled products in order to emphasize environmental issues, it is necessary to add advertisements to bags filled with them and collect costs. Thus, a method of distributing agricultural or horticultural materials themselves for free or at low cost has not yet been disclosed.
[0014]
[Problems to be solved by the invention]
An object of the present invention is to solve the above-mentioned situation, and relates to a relation between reprocessing cost, product quality, and selling price in recycling industrial waste such as sludge, construction soil, paper sludge, and livestock manure. However, it is an object of the present invention to construct a system that is economically reasonable for smoothly and widely distributing products.
[0015]
[Means for Solving the Problems]
As a result of studying to solve the above-mentioned problems, it was found that it was difficult to reduce such a large amount of industrial waste by studying only from the manufacturing method. Therefore, as a result of diligent examination, the corporation and individual who agree with the intent of the present inventor collect reprocessing costs for manufacturing high-quality products by becoming advertisers, and use natural soil and waste that does not use various resources. It was found that the problem could be solved by distributing free or inexpensive soil and soil improvers made from lime.
[0016]
Not only farmers who use agricultural and horticultural materials, but also ordinary consumers can understand the gist of the present inventor, and if materials become available for free or at very low prices, it would be impossible to imagine in the past. It is obvious that a large amount of industrial waste will be valuable and effectively used.
[0017]
In the present invention, the sludge is water and solids such as sediment and soil, suspended solids and the like taken from rivers and lakes, and these solids and water removed during the production of drinking water and industrial water are removed. With a water content of generally 80 to 99.9% by weight.
[0018]
The construction-generated soil in the present invention is earth and sand mainly generated by excavation and creation by civil engineering work, and the moisture and soil constituent components differ depending on the geology and environment.
[0019]
Agricultural and horticultural materials in the present invention are various materials used for agriculture, horticulture, greening, cultivation of individual plants, etc., and in the present invention, mainly, materials used as plant growth bases are targeted. Become.
[0020]
The soil according to the present invention is soil used as a plant growth base or a material that substitutes for soil, and includes a mixture of various materials in consideration of plant growth and workability. The conditions required for the soil according to the type and cultivation method of the plant are various, but the soil that can be produced in the present invention includes a culture soil for flowers, a culture soil for vegetables, a culture soil for fruit trees and flowers, a soil for growing various seedlings, and a soil for growing seedlings. Examples include culture soil, seedbed soil, and a greening base material.
[0021]
The soil improving material in the present invention is a material mainly used for improving the physicochemical properties of soil on agricultural land or the like, and includes various organic and inorganic materials.
[0022]
The papermaking sludge in the present invention is a suspension containing a papermaking raw material discharged in a papermaking process, and various papermaking chemicals such as a pulp fiber, a filler, a paper strength enhancer, a filler retention improver, and a sizing agent. It contains. Although the components and concentrations thereof are not constant, the papermaking sludge used in the present invention is limited to those containing pulp fibers and containing no harmful substances that inhibit plant growth. By adding the papermaking sludge to the sludge, the sludge can be easily dewatered.
[0023]
The livestock waste in the present invention is waste mainly composed of livestock manure such as cow manure, pig manure, and poultry manure, which is discharged from a farm that operates cattle, pig, poultry, and the like. These livestock manures contain easily decomposable organic matter containing nitrogen, and by controlling the amount of livestock waste, promote rapid fermentation of raw materials accompanied by a rise in temperature. In addition, it is possible to produce a soil or soil improvement material containing a fertilizer component such as nitrogen, phosphorus, and potash that promotes plant growth and has a plant growth promoting effect.
[0024]
The recycled film in the present invention is a film made of plastic regenerated from used plastic, and includes a film that is once melted and regenerated, and a film that is used as it is by washing a used bag. Examples of the plastic include polyethylene, polypropylene, polyethylene terephthalate, and polyvinyl chloride.
[0025]
BEST MODE FOR CARRYING OUT THE INVENTION
The sludge used in the present invention is a mixture of water and solid matter separated from water such as rivers and lakes when producing purified water or industrial water, for example, industrial waste generated in water purification plants and paper mills. It is.
[0026]
The construction-generated soil used in the present invention is, for example, earth and sand generated by civil engineering works such as excavation of tunnels, creation of forests and wilderness. It is preferable that the clay, silt, and sand are present in an appropriate amount at a water content of 70% or less.
[0027]
The filling bag used in the present invention may be made of commonly used materials such as paper and vinyl. It is not particularly limited to recycled products unless it has excessive quality and fancy design, but the gist of the inventor is to give priority to environmental preservation and add as little environment as possible. desirable. Therefore, a filling bag made of waste paper that has been excessively deinked or made highly white or a film or the like that has unnecessarily strong strength is not preferred.
[0028]
The papermaking sludge used in the present invention is a sludge-like suspension discharged in a papermaking process, and 90% or more of the solid content is derived from papermaking raw materials. Above all, the pulp fiber content is high, and this pulp fiber serves as a dehydration aid and is utilized by microorganisms as a carbon source during fermentation. Examples of such papermaking sludge include screen reject in the pulp selection process, cleaner reject, and white water in the papermaking process.
[0029]
The livestock waste used in the present invention is a waste mainly composed of livestock excreta discharged from a facility operating a livestock industry, and examples thereof include cattle excreta, pig excreta, and chicken dung. When used as a raw material for a culture soil or a greening base material in the present invention, livestock manure alone can be used, but it may be mixed with bedding or the like depending on the method of breeding by a livestock farmer.
[0030]
In the case of producing the fermented product in the present invention, after mixing wastewater and papermaking sludge in a tank equipped with a stirrer or the like, water is removed by coagulation sedimentation or pressing, and livestock manure is further mixed. The fermentation may be carried out outdoors or in a compost house. Generally, it is necessary that the solid content of livestock manure is 5% or more of the solid content in the sludge. The fermentation period varies depending on the raw material, but is about one month to two years. During the fermentation, the fermentation can be performed more efficiently by appropriately stirring, adjusting the water content, aeration, etc., and the fermentation period can be shortened. As a guide for the completion of the fermented product, an evaluation method generally used in compost production or the like may be used to confirm that the fermented product does not adversely affect the growth of the plant.

The fermented product produced according to the present invention has most of the organic matter decomposed by fermentation unless only the hardly decomposable organic matter is used as a raw material, and the remaining organic matter is mixed with the soil-derived inorganic matter in the sludge. It becomes soil-like material. After completion of the fermentation, it can be easily pulverized and granulated using an appropriate device, and used after processing if necessary. In the production of soil and soil improvement materials, the fermented products are manufactured as they are or mixed with appropriate materials, and then sold in bags.
[0032]
In the filling bag used in the present invention, advertisements of corporations and individuals are described. These are not particularly limited in terms of format, design, and the like, but are desirably in agreement with efforts to solve environmental problems. In addition, these sales routes are not limited to conventional distribution such as the above-mentioned supermarkets, home centers, horticultural stores, agricultural cooperatives, etc., but are limited to any routes which can obtain the consent of the inventor. It is also possible to distribute free of charge in public places.

【Example】
Hereinafter, one example of the present invention will be described, but the present invention is not limited to these examples.
[0034]
Example A papermaking sludge containing kraft pulp fiber, which had been exposed to a hardwood with a moisture content of 99%, was mixed and stirred with 1000 L of wastewater having a moisture content of 95% generated in the production of industrial water so that the solid content of the pulp fiber was 30%. Dehydration was performed using a press to reduce the water content to 55%.
[0035]
Chicken manure was mixed with the cake-like sludge and papermaking sludge complex after dehydration so as to have a ratio of 10% with respect to the solid content of the complex, and deposited and fermented outdoors. The sediment fermentation was cut back as appropriate and the fermentation was completed after about one month.
[0036]
5 L of the fermented product was packed in a bag processed from a recycled polyethylene film. The size of the printed surface of the bag was about 2000 cm 2, and about 1000 cm 2 could be used as a space other than a part where necessary items such as product descriptions were described, that is, a space for placing an advertisement.
[0037]
A mixture of 3 L of river sand and 1 L of a fermented product was packed in a pot, and seeds of Komatsuna were sown. Komatsuna was raised in a sunny place with proper watering. No fertilizer was given during this time. The growth was good, and it became about the same size as the commercially available Komatsuna in about 30 days. In general, by adding a fermented product as a soil improving material to sand where plants are difficult to grow, it was possible to obtain soil suitable for growing Komatsuna.
[0038]
By adding a soil conditioner consisting of only waste and recycled products to soil where plant growth is difficult, it has become possible to improve the soil to high productivity. It is obvious to everyone that this soil conditioner contributes to the reduction of waste and environmental protection, and it contributes to the enhancement of the image of the advertiser. This advertising cost was about 70% of the production cost of the soil conditioner, and could be sold at 40% of the previous price.
[0039]
【The invention's effect】
As explained above, according to the present invention, agricultural and horticultural materials manufactured from wastewater discharged during the production of tap water or industrial water, or construction-generated soil are filled in a bag made of waste paper or recycled film, By adding an advertisement to the filled bag and collecting the cost, agricultural and horticultural materials can be distributed free or at low cost. In addition, it is possible to replace some or all of materials that have been used as soil and soil improvement materials, not only to save materials but also to reuse various wastes. Thus, there is no need to dispose of waste, thereby contributing to environmental conservation.
