大丈夫？

新しい技術を使ってより効率的に資源再生、二酸化炭素排出削減を実現する。

もちろんミミズを飼ってコンポストで処理することも可能であれば効率的でしょうが、少子高齢化の日本で、誰が生ゴミを運んでコンポストに捨て、誰がコンポストの整理をするんでしょうか？

業務用の粉砕機で粉砕したものを下水に流してはいけないなんて、世界共通の規制です。水質汚濁というよりかは下水管のつまりを防ぐために規制されるのはある程度当然ですが、日本では実証実験を行って、ディスポーザーの使用が下水道システムにほとんど問題ないことが実証されています。

日本の科学技術的やり方より、ヨーロッパの伝統的農法の方が正しいかも知れませんが、ヨーロッパの多くの国で粉砕機による粉砕ゴミを下水に流してはいけないなんて、日本でも同じですよ。工場排水の基準がありますからね。

今までと異なり、新しいやり方に変わっていくことが潮流に乗るってことだと思いますが？

History

The garbage disposal unit was invented in 1927 by John W. Hammes, an architect working in Racine, Wisconsin.[1] He applied for a patent in 1933 that was issued in 1935.[2] His InSinkErator company put his disposer on the market in 1940.[citation needed]

Hammes' claim is disputed, as General Electric introduced a garbage disposal unit in 1935,[3][4] known as the Disposall.

In many cities in the United States in the 1930s and the 1940s, the municipal sewage system had regulations prohibiting placing food waste (garbage) into the system.[5] InSinkErator spent considerable effort, and was highly successful in convincing many localities to rescind these prohibitions.[6]

Many localities in the United States prohibited the use of disposers.[7] For many years, garbage disposers were illegal in New York City because of a perceived threat of damage to the city's sewer system. After a 21-month study with the NYC Department of Environmental Protection,[8] the ban was rescinded in 1997 by local law 1997/071, which amended section 24-518.1, NYC Administrative Code.[9]

In 2008, the city of Raleigh, North Carolina attempted a ban on the replacement and installation of garbage disposers, which also extended to outlying towns sharing the city's municipal sewage system, but rescinded the ban one month later.[10][11]

で、さらにこの部分ね。Rationaleってわかるかな？

https://en.wikipedia.org/wiki/Garbage_disposal_unit#Rationale

Rationale
Food scraps range from 10% to 20% of household waste,[20] and are a problematic component of municipal waste, creating public health, sanitation and environmental problems at each step, beginning with internal storage and followed by truck-based collection. Burned in waste-to-energy facilities, the high water-content of food scraps means that their heating and burning consumes more energy than it generates; buried in landfills, food scraps decompose and generate methane gas, a greenhouse gas that contributes to climate change.[21]

The premise behind the proper use of a disposer is to effectively regard food scraps as liquid (averaging 70% water, like human waste), and use existing infrastructure (underground sewers and wastewater treatment plants) for its management. Modern wastewater plants are effective at processing organic solids into fertilizer products (known as biosolids), with advanced facilities also capturing methane (biogas) for energy production.[22][23]

Environmental impact

Kitchen waste disposal units increase the load of organic matter that reaches the water treatment plant, which in turn increases the consumption of oxygen.[30] Metcalf and Eddy quantified this impact as 0.04 pounds (18 g) of biochemical oxygen demand per person per day where disposers are used.[31] An Australian study that compared in-sink food processing to composting alternatives via a life-cycle assessment found that while the in-sink disposer performed well with respect to climate change, acidification, and energy usage, it did contribute to eutrophication and toxicity potentials.[32]

This may result in higher costs for energy needed to supply oxygen in secondary operations. However, if the waste water treatment is finely controlled, the organic carbon in the food may help to keep the bacterial decomposition running, as carbon may be deficient in that process. This increased carbon serves as an inexpensive and continuous source of carbon necessary for biologic nutrient removal.[33]

One result is larger amounts of solid residue from the waste-water treatment process. According to a study at the East Bay Municipal Utility District's wastewater treatment plant funded by the EPA, food waste produces three times the biogas as compared to municipal sewage sludge.[34] The value of the biogas produced from anaerobic digestion of food waste appears to exceed the cost of processing the food waste and disposing of the residual biosolids (based on a LAX Airport proposal to divert 8,000 tons/year of bulk food waste).[35]

In a study at the Hyperion sewage treatment plant in Los Angeles, disposer use showed minimal to no impact on the total biosolids byproduct from sewage treatment and similarly minimal impact on handling processes as the high volatile solids destruction (VSD) from food waste yield a minimum amount of solids in residue.[35]

Power usage is typically 500?1,500 W, comparable to an electric iron, but only for a very short time, totaling approximately 3?4 kWh of electricity per household per year.[36] Daily water usage varies, but is typically 1 US gallon (3.8 L) of water per person per day,[37] comparable to an additional toilet flush.[38] One survey of these food processing units found a slight increase in household water use.[39]

Garbage disposal unit

From Wikipedia, the free encyclopedia

A garbage disposal unit installed under a kitchen sink

A garbage disposal unit (also known as a waste disposal unit, food waste disposer (FWD), in-sink macerator, garbage disposer, or garburator) is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap. The device shreds food waste into pieces small enough?generally less than 2 mm (0.079 in) in diameter?to pass through plumbing.

History
The garbage disposal unit was invented in 1927 by John W. Hammes, an architect working in Racine, Wisconsin.[1] He applied for a patent in 1933 that was issued in 1935.[2] His InSinkErator company put his disposer on the market in 1940.[citation needed]

Hammes' claim is disputed, as General Electric introduced a garbage disposal unit in 1935,[3][4] known as the Disposall.

In many cities in the United States in the 1930s and the 1940s, the municipal sewage system had regulations prohibiting placing food waste (garbage) into the system.[5] InSinkErator spent considerable effort, and was highly successful in convincing many localities to rescind these prohibitions.[6]

Many localities in the United States prohibited the use of disposers.[7] For many years, garbage disposers were illegal in New York City because of a perceived threat of damage to the city's sewer system. After a 21-month study with the NYC Department of Environmental Protection,[8] the ban was rescinded in 1997 by local law 1997/071, which amended section 24-518.1, NYC Administrative Code.[9]

In 2008, the city of Raleigh, North Carolina attempted a ban on the replacement and installation of garbage disposers, which also extended to outlying towns sharing the city's municipal sewage system, but rescinded the ban one month later.[10][11]

Adoption and bans
In the United States, 50% of homes had disposal units as of 2009,[12] compared with only 6% in the United Kingdom[13] and 3% in Canada.[14]

In Sweden, some municipalities encourage the installation of disposers in order to increase the production of biogas.[15]

In Britain, Worcestershire County Council and Herefordshire Council started to subsidize the purchase of garbage disposal units in 2005, in order to reduce the amount of waste going to landfill and the carbon footprint of garbage runs.[16] However, the use of macerators was banned in Scotland in 2016[17] in non-rural areas where food waste collection is available, and banned in Northern Ireland in 2017. They are expected to be banned for businesses in England and Wales in 2023.[18][needs update] The intention is to reduce water use.

Many other countries in Europe have banned or intend to ban macerators. The intention is to realise the resource value of food waste, and reduce sewer blockages.[19]

Rationale
Food scraps range from 10% to 20% of household waste,[20] and are a problematic component of municipal waste, creating public health, sanitation and environmental problems at each step, beginning with internal storage and followed by truck-based collection. Burned in waste-to-energy facilities, the high water-content of food scraps means that their heating and burning consumes more energy than it generates; buried in landfills, food scraps decompose and generate methane gas, a greenhouse gas that contributes to climate change.[21]

The premise behind the proper use of a disposer is to effectively regard food scraps as liquid (averaging 70% water, like human waste), and use existing infrastructure (underground sewers and wastewater treatment plants) for its management. Modern wastewater plants are effective at processing organic solids into fertilizer products (known as biosolids), with advanced facilities also capturing methane (biogas) for energy production.[22][23]

Operation

The parts of a garbage disposal

Top view of sink, with splash guard visible

A modern disposal unit
A high-torque, insulated electric motor, usually rated at 250?750 W (1?3?1 hp)[24] for a domestic unit, spins a circular turntable mounted horizontally above it. Induction motors rotate at 1,400?2,800 rpm and have a range of starting torques, depending on the method of starting used. The added weight and size of induction motors may be of concern, depending on the available installation space and construction of the sink bowl. Universal motors, also known as series-wound motors, rotate at higher speeds, have high starting torque, and are usually lighter, but are noisier than induction motors, partially due to the higher speeds and partially because the commutator brushes rub on the slotted commutator.[25][26]

Inside the grinding chamber there is a rotating metal turntable onto which the food waste drops. Two swiveling and two fixed metal impellers mounted on top of the plate near the edge then fling the food waste against the grind ring repeatedly. Sharp cutting edges in the grind ring break down the waste until it is small enough to pass through openings in the ring. Sometimes the waste goes through a third stage where an undercutter disc further chops it, whereupon it is flushed down the drain.

Usually, there is a partial rubber closure, known as a splashguard, on the top of the disposal unit to prevent food waste from flying back up out of the grinding chamber. It may also be used to attenuate noise from the grinding chamber for quieter operation.

There are two main types of garbage disposers?continuous feed and batch feed. Continuous feed models are used by feeding in waste after being started and are more common. Batch feed units are used by placing waste inside the unit before being started. These types of units are started by placing a specially designed cover over the opening. Some covers manipulate a mechanical switch while others allow magnets in the cover to align with magnets in the unit. Small slits in the cover allow water to flow through. Batch feed models are considered safer, since the top of the disposal is covered during operation, preventing foreign objects from falling in.

Waste disposal units may jam, but can usually be cleared either by forcing the turntable round from above or by turning the motor using a hex-key wrench inserted into the motor shaft from below.[27] Especially hard objects accidentally or deliberately introduced, such as metal cutlery, can damage the waste disposal unit and become damaged themselves, although recent advances, such as swivel impellers, have been made to minimize such damage.[citation needed]

Some higher-end units have an automatic reversing jam clearing feature. By using a slightly more complicated centrifugal starting switch, the split-phase motor rotates in the opposite direction from the previous run each time it is started. This can clear minor jams, but is claimed to be unnecessary by some manufacturers: Since the early sixties, many disposal units have utilized swivel impellers which make reversing unnecessary.[28]

Some other kinds of garbage disposal units are powered by water pressure, rather than electricity. Instead of the turntable and grind ring described above, this alternative design has a water-powered unit with an oscillating piston with blades attached to chop the waste into fine pieces.[29] Because of this cutting action, they can handle fibrous waste. Water-powered units take longer than electric ones for a given amount of waste and need fairly high water pressure to function properly.[citation needed]

Environmental impact
Kitchen waste disposal units increase the load of organic matter that reaches the water treatment plant, which in turn increases the consumption of oxygen.[30] Metcalf and Eddy quantified this impact as 0.04 pounds (18 g) of biochemical oxygen demand per person per day where disposers are used.[31] An Australian study that compared in-sink food processing to composting alternatives via a life-cycle assessment found that while the in-sink disposer performed well with respect to climate change, acidification, and energy usage, it did contribute to eutrophication and toxicity potentials.[32]

This may result in higher costs for energy needed to supply oxygen in secondary operations. However, if the waste water treatment is finely controlled, the organic carbon in the food may help to keep the bacterial decomposition running, as carbon may be deficient in that process. This increased carbon serves as an inexpensive and continuous source of carbon necessary for biologic nutrient removal.[33]

One result is larger amounts of solid residue from the waste-water treatment process.

In a study at the Hyperion sewage treatment plant in Los Angeles, disposer use showed minimal to no impact on the total biosolids byproduct from sewage treatment and similarly minimal impact on handling processes as the high volatile solids destruction (VSD) from food waste yield a minimum amount of solids in residue.[35]

Power usage is typically 500?1,500 W, comparable to an electric iron, but only for a very short time, totaling approximately 3?4 kWh of electricity per household per year.[36] Daily water usage varies, but is typically 1 US gallon (3.8 L) of water per person per day,[37] comparable to an additional toilet flush.[38] One survey of these food processing units found a slight increase in household water use.[39]

根拠

食品廃棄物は家庭ごみの10%から20%を占めており[20]、都市ごみの厄介な要素であり、内部保管からトラックによる収集まで、各段階で公衆衛生、衛生、環境問題を引き起こしています。廃棄物発電施設で焼却される食品廃棄物は水分含有量が高いため、加熱と燃焼で生成されるエネルギーよりも消費されるエネルギーの方が多くなります。埋立地に埋められると、食品廃棄物は分解してメタンガスを生成し、気候変動に寄与する温室効果ガスとなります。[21]

ディスポーザーを適切に使用する【前提】は、食品廃棄物を事実上液体（人間の排泄物のように平均70%が水分）と見なし、既存のインフラストラクチャ（地下下水道や廃水処理施設）を使用して管理することです。現代の廃水処理施設は、有機固形物を肥料製品（バイオソリッドと呼ばれる）に処理するのに効果的であり、高度な施設ではメタン（バイオガス）を回収してエネルギー生産も行います。[22][23]
