How do you think of the new waste classification method in Shanghai?

I am foolish to see this garbage classification method.

Indeed, Japanese garbage is classified and thrown at fixed points, but everyone is very conscious. But you have to be comprehensive, don’t you?

since you all said how Japan is doing, let’s talk about the garbage classification in Japan first, and then come back to Tucao Shanghai. This is a stupid garbage sorting policy.

Japan mainly uses incineration and landfill to dispose of garbage. Although policies vary and rules vary from place to place, the overall logic of classification is clear and can even be described as simple and crude: You can pick out things that are not very good to burn .

Specifically, Japanese garbage can be roughly divided into four categories.

< UL > < li > combustible garbage < / Li > < li > non-combustible garbage < / Li > < li > resource garbage < / Li > < li > crude garbage < / Li > < / UL >

Let’s talk one by one from the back.

First of all, Coarse garbage . This is a special category, specifically large items, wardrobes, tables and beds, which need to be paid extra to be processed. This is beyond our scope of discussion.

Besides < b > resource garbage . That’s understandable, just look at the recyclable ones, cardboard boxes, clean newspapers, PET beverage bottles, pop cans and so on. Actually, we have done a good job of this. We are very conscious of the classification, because we can exchange it for money.

Finally, domestic waste is classified as < b > flammable and < b > non-flammable .

Non-flammable means picking out things that are obviously not easy to burn, such as metal and porcelain glass, specifically pots and pans, umbrellas and kitchen knives. The impression is that there are places where plastic is required to be picked out, as if it is easier to produce dioxins, but garbage has to be packed with plastic tapes, right? With the continuous improvement of incineration technology, plastic bags are burned directly in most places nowadays.

The rest is flammable. Just pack it and throw it away.

This is the garbage classification of Wenjing District. Can you appreciate whether it is easy to separate?

Osaka people are more rugged (especially Osaka City, Kansai Circle is not the same), combustible and non-combustible, everything is taken to burn. Because garbage classification is too rough, Osaka is not much tucking out by other Japanese. What’s more wonderful is that it’s flammable and non-flammable, but it’s also strange for brain circuits to force foaming utensils, such as plastic lunch boxes / foaming containers in supermarkets, to be picked up and recycled separately. (Voluntary recycling elsewhere, such as collecting it for supermarkets)

So on the issue of classification, in fact, people are not required to do many complicated things.

Well, let’s talk about the killing places. Flammable garbage (including kitchen waste) is collected only two or three times a week, and it will taste at home one more day in summer. If you miss one, it will be a disaster. When I first came to Japan in my early years, I asked my Japanese teacher how to solve this problem. She said that just leave it in the garage or yard for the time being. I%… & amp; *, almost MMP.

Why is the system so anti-human? Because the government is too poor to employ so many sanitation workers to collect them every day.

Fortunately, it is flexible in terms of time, although the system requires that garbage be taken out before 8 o’clock on the day of collection and put in a designated place. But many people throw out their garbage the night before or in the middle of the night, and all of us turn a blind eye to it.

Despite budget constraints, the timing of garbage collection is a very, very pitiful thing. But throwing garbage at any time is almost just needed, which is the same for everyone.

So in fact, as long as you don’t live in that kind of special to old apartment (over 30 years old), there is still a way to alleviate it.

If you live in a Japanese-style household building (“Robot Cat” has always seen it? The protagonist’s kind) usually has a yard with a garage, and plastic bags are sealed and placed in the corner of the yard.

If a collective house is built, a slightly new house will be considered in this matter. Generally, there will be a special public garbage bin in which households can throw it at any time. On the day of garbage collection, the property or landlord will unlock the garbage bin and let the garbage truck take it away.

Yes, you heard me right. The garbage bin is usually locked. This belongs to the welfare of the household/owner and is not allowed to be thrown in by outsiders.

It’s more convenient to update the building.

Each building will have a special garbage storage room. Rubbish is packed in large plastic bags, and the room is usually equipped with industrial deodorization equipment. You say that a little taste is not boastful, but overall it is acceptable.

The room is usually equipped with a faucet and a drainage device. After the garbage is collected, the water will be washed clean. So even if it’s a garbage storage room, the hygiene can go well. Of course, the property is responsible for this, and the cost is naturally included in the property cost.

The plastic baskets of various colors on the left are used to hold all kinds of resource rubbish.

The movable iron frame on the right is used to hold combustible garbage. Photographs are collected three times a week, 2, 4, 6 times (marked on the iron frame), and at most every three days. Four iron frames like this are probably enough to throw a building (60-80 households) for about three days.

Finally, it is emphasized that if the building is equipped with the garbage storage room mentioned later, any kind of garbage other than coarse can be thrown away at any time, not subject to fixed-point and regular restrictions. By the appointed date, the property will take things out to the garbage truck.

Of course, convenience is a cost, which is borne by all the owners. Although Japan does not share the area equally, it means almost the same. This garbage storage room maintenance, cleaning and so on, we also have to pay property fees.

The basic information has been introduced. To sum up, here is the summary.

< ol > < li > obviously means that resources should be separated (harmful ones should also be picked out) < / Li > < li > and those that are not burnable should also be separated out < / Li > < li > The remaining large plastic bags will be thrown in a pack < / Li > < li > fixed-time huge pit, but if you are willing to spend a little money, you can have a temporary garbage storage site, that is, you can throw it at any time.

That is to say, for ordinary people, throwing garbage is not a very obvious burden, nor is it very painful.

If you’re unwilling to pay a little extra cost, or really bad. It is really a fatal thing to throw garbage at regular intervals, which is also a big problem faced by low-income groups such as international students. If you want to save money on property/cleaning/rent, you have to deal with it yourself, either by not cooking at home (many old-fashioned, cheap single apartments do have only one electric stove and can only cook something) or by purchasing a kitchen waste processor at your own expense.

Although very expensive, after all, the audience is small, just a supplementary program.

By the way, one more spoon of kitchen waste processor, which is described here as a garbage can type, through biological decomposition or dry crushing to deal with garbage. For example, the following. Not under the sink.

I know you want to ask about the kind under the sink, which has special requirements for the drainage system. Private installation is not allowed in many parts of Japan. More importantly, 99.9% of the houses that can afford the kitchen waste disposal trough have dedicated garbage storage rooms, so it’s not really expected that this thing will solve all the problems.

Talk to a few friends who use this kind of garbage processor. The general opinion is that this thing is more delicate than imagined. The property also informs from time to time that the drainage of building X is blocked again. Be careful not to throw anything in.

Others can take a look at my previous answers.

Is the kitchen garbage processor reliable?

Then let’s talk about Shanghai again. I’m really foolish to see this problem. Let’s talk a little.

Lagged supporting facilities

First of all, what kind of ghost is dry garbage and wet garbage? Why do biscuits count wet rubbish, used paper towels count dry rubbish?

Until I see the following statement

pigs can eat wet waste, pigs can’t eat dry garbage,

The summary is in place, but why is it so categorized? Or how to deal with it? We know that incineration and burial are the main means of disposal of garbage at present. So which one burns which one buries it?

Dry garbage to burn, wet garbage buried? That’s not the case. The pots and pans are all garbage.

After the wet garbage is dried, it is burned and the dry garbage is buried. That’s not the case. Why can’t waste paper or something be burned?

So what the hell is going on? After reading the news and thinking about it, I finally realized that < b > China wants to overtake the garbage disposal in a roundabout way.

Specifically speaking, the existing waste treatment system should be incineration + landfill treatment, jumping directly to more advanced biodegradation + incineration + landfill treatment.

This step is a bit big, won’t you accidentally pull the egg? After all, we haven’t fully figured out what to burn, and to what extent have our biochemical degradation plants been built? It’s almost true.

This is the news last month.

The largest wet garbage resource utilization project in Shanghai will be put into operation by the end of next year

Production is not expected until the end of next year. Even if put into production, the processing capacity is 1,000 tons per day. The number of wet garbage produced in Shanghai in 2018 is 4,000 tons per day, and it is estimated that it will rise. This gap is a bit big.

That is to say, at this time point (June 2019) and for a long time to come, the big head of wet garbage may not be able to be disposed of alone. It can’t be handled or not. It can only be handled in the old way. So under this answer, many people say that the good garbage is actually mixed up and pulled away. It’s really realistic that such magical things can’t be done well.

Shanghai is still the case, and other supporting facilities are less likely to be built in the short term. How? Cool sauce.

This community handles 75% of the wet garbage by itself, and the first pilot project of reducing the emission of domestic garbage sources in Shanghai has been successful–Shangshan

See this pilot?

That is to say, in the near future, the gap of wet garbage will encourage families/communities to dispose of it by themselves. Pushing a wave of garbage disposal to boost domestic demand?

And if you look at the photos, the garbage disposal station at the community level actually uses two ordinary straight-row kitchen waste disposal units, which are ground up and discharged directly into the sewage system. It’s hard to say what happens to a city with tens of millions of people.

Japan’s garbage processors, which are installed under the sinks, are not very popular, and, as I said earlier, the main cities have banned such direct-row processors. If you want to use it, you have to deal with it first and then drain it into the sewerage system.

Of course, it is also possible that Japan is too worried about it. After all, the amount of excrement emitted by cities every day is astronomical. These grinded wet garbage may not bring more problems than excrement. But it’s always a mystery.

Chaotic and inconsistent classification logic

I think Japan’s garbage sorting is good because of its simple sorting logic. The logic of separating wet and dry garbage in Shanghai is very confusing, and sometimes it is difficult to harmonize with each other.

For example, since vegetable leaves are wet garbage, why dumpling cotyledons are dry garbage? Aren’t you all leaves?

why do fish bones count wet waste * why do pigs and cattle bones even dry rubbish? Aren’t you all bones?

Officially speaking, things like big bones are too hard to damage terminal equipment, but I don’t think that’s a problem for large crushing equipment.

In addition, from the point of view of perishability, raisins, honey, salted fish, which are almost difficult to decay, should be classified as dry garbage?

although it is possible to use classical pig to eat, it can achieve good results, but many people, including myself, should not have actually raised pigs. It’s also hard to put all the body into the pig’s mind. I have to say that there are so many special cases of garbage sorting, which is more than when I was studying high school chemistry. Horizontal comparison, this kind of classification work is really a very difficult type of work, without training can not be on the job, which makes it really difficult for ordinary families to do.

Some people say that there is APP, but the need for APP itself is a big problem, indirectly indicating that our garbage classification logic is too confusing, too many special cases, the complexity has almost reached the level of one treatment.

Moreover, it is difficult to avoid confusion if the standard is not clear and the fine is strictly enforced. For example, how big bones are big bones? Chicken bones don’t count. What about Turkey bones?

To be honest, the closer you look at this classification rule, I think this wet garbage standard is just tailored for household-level garbage processors. This is intended to push a wave of rhythm, so rich can consider investing in a wave of Ha, of course, don’t look for me.

Finally, let’s discuss a question of reflection. First look at the classification criteria

What kind of garbage is that slightly larger amount of oil (hundreds to thousands of milliliters), such as the sauce part of a pan of boiled fish?

Directly pour the drain like milk? I’m afraid not.

Wet garbage according to the standard of leftover soup? After all, wet garbage also needs to drain as much water as possible. I’m afraid it’s not appropriate for you to pour such a lot of liquid directly into it.

Dry garbage? That would be even more inappropriate.

I checked for half a day and did not find out how to calculate it. A friend who knows can tell me in the comments.

Someone suggested that you can’t throw away the oil like that before?

But I did throw it directly. Because as I understand it, a small amount of waste oil that is not easily separated can be burned directly with other combustible waste.

I don’t know how to deal with it. There are better ways to teach me.

For my part, if it’s in Japan, use a special oil curing agent or oil suction bag, similar to this, after curing, throw it away as combustible garbage.

The rational method of using

If at home, fill the plastic bags with napkins, paper towels and other things to make a simple oil-absorbing bag, and then throw away the plastic bags after multi-layer packaging.

But this treatment is really not suitable for the new waste classification method, so I am also desperate.

Some people even give the solution is to pour the toilet directly, the reason is basically “put more detergent will not dirty the toilet” and “I do that, never blocked”.

How dare you think about your home?!! So let’s not talk about it and waste each other’s time.

Suffocating wet garbage bags

This is a tasty operation. Let’s take a look at the wet garbage bin first.

They look like this.

Look like this

I’m X. Isn’t this an ordinary plastic trash can? There’s no extra sealing, wet garbage… Just throw it in?

reminds me of the pig compost *

It was better to have plastic bags separated from each other. Now they are mixed together directly, so they are not fermented directly.

What’s more, without plastic bags, would not garbage come into direct contact with the bucket? I don’t want to talk about it. I ask a very real question: , who will brush the trash cans with all kinds of dirty leftovers?

How to brush? What brush do you use? Where does water come from? Where is the sewage discharged? These are all problems.

Or are you not going to brush it? This trash can is definitely the source of pollution in the source of pollution. Is that really good?

My personal idea is that if wet garbage must be done like this, it can be done like this: wet garbage can be made into standard size, and there are certain sealing measures. Then when the garbage truck comes, it takes the garbage bin full of garbage and replaces it with clean one.

The trash can is pulled to the treatment plant, dumped, cleaned and recycled.

It can be done technically and cost… It’s not that bad. But now the dedicated wet garbage truck should be gradually put on line, and it is unlikely to turn this way again.

At least put a plastic bag on the garbage can, which is good for everyone.

It’s just that plastic bags are all put on the trash cans. Why do people have to break bags?
