Early the next morning, Zhang Chao and the others came to the designated place, and the quarry that used to be used to build the road was also a place that Zhang Chao was more familiar with, because they had also worked there for a while.

But when they came here again, they found that the gravel field had been enclosed by a wall, leaving only an iron gate.

There was also a wire mesh on top of the fence, and it was clear from the flashing red lights that it was a forbidden place to touch.

Because from the moment I came to this Huaxia country, I was told of several danger signs.

Among the signs that can be life-threatening, this regular and constantly flashing red light is the highest level of danger warning.

This warning means that you can die if you touch it, especially the carcasses of small animals that often appear under the barbed wire, which proves to everyone that they are terrible and intimidating.

There is a row of iron houses not far from the fence inside the iron gate, an iron house near the iron gate is used to register and upload information about garbage classification, and the other iron houses are equipped with various tools used in the garbage sorting process.

After Zhang Chao and his group of 300 people registered with their identity numbers in the office, each of them received the tools they needed for their work, gloves, masks, a small iron hook and a bucket truck.

Once they had all the tools, they were taken to the hill-like garbage heap.

A full-fledged member of the Huaxia Kingdom introduced the garbage samples at the entrance of the sorting and stacking points around the garbage heap one by one, as well as the corresponding remuneration for each catty of the garbage.

Of course, for these displaced people, who have almost zero level of cultural knowledge, it is impossible to distinguish what kind of material the garbage in the other world is made of.

Especially for those different plastic materials, it is good to be able to tell that this is a plastic product under a simple introduction.

As for the garbage sent here, the large plastic products, cardboard, glass bottles and other high-value items have actually been cleaned up by the waste pickers, and the rest is just something that they don't even look at.

Therefore, for the primary classification of these garbage, Wei Minsheng has only identified ten kinds of vegetable and fruit peel food waste, paper, textile fiber, wood, porcelain, glass, plastic, rubber, metal and solid construction waste.

Among the ten kinds of garbage, solid construction waste is the most convenient to collect, and with the right means of transportation, a labor force can easily collect and transport such waste to a designated place in a day.

Although the remuneration price of construction waste is the lowest, only one yuan of Huaxia yuan is paid for two hundred catties of this kind of garbage, but a laborer can also get at least five yuan or more Huaxia yuan.

This solid construction waste is eventually used for landfills in the roadbed and as fill in the shore forts on the dock site.

Due to its light weight and high recyclability rate, plastic waste can be paid 10 yuan Huaxia coin.

However, since the collection of various types of garbage has been measured in advance, and the corresponding remuneration calculation parameters for each type of garbage have been adjusted, the final remuneration is generally similar regardless of the type of garbage selected for collection.

Vegetable and fruit peel food waste is collected and sent to the newly built biogas digester of the treatment site, which is decomposed by anaerobic bacteria, and the biogas produced is used to generate electricity, providing sufficient power resources for this relatively independent garbage disposal site.

A row of charging stations has also been set up near the gate of the garbage disposal site, and the surplus electricity is used to charge the electric vehicles that transport the garbage.

The three types of garbage, namely paper, wood and textile fiber, which are highly polluted, are sent to a special incinerator in the treatment site for incineration because they produce less harmful gases during combustion and are easily degraded naturally in nature.

The heat generated during the incineration process is used to generate hot water to clean the surface of the solid waste.

The cleaned sewage is mixed with vegetable and fruit peel food waste and sent to the biogas digester, and the waste heat of the sewage is used to increase the temperature in the biogas digester to ensure that several biogas digesters run in the temperature range with the highest gas production at any time.

In such a situation, the processing capacity and gas production capacity of the digester can reach a very desirable level.

Paper and textile fibres that are suitable for recycling are sent to the recyclable stockpile.

The tiles that have been discarded during the renovation process are cut into porcelain tiles of various sizes after cleaning and are sorted and stored according to the color and pattern of the surface.

After a certain number of porcelain tiles of similar colors and patterns have been reached, they can be used as wall decoration materials for new bathrooms.

Broken porcelain shards and porcelain pieces left over from processing can be used to decorate the floor of the toilet and some pavement.

The tiled floor has high slip resistance, but also makes the floor easier to clean, and more beautiful and practical than gravel pavement.

Although the recycling value of those broken glass is not high, if it is discarded randomly, the sharp corners can easily cause damage to people, and this potential injury will not disappear over time.

Therefore, in order to minimize the possible harm of these items, Wei Minsheng still decided to collect them.

Regardless of how much value is created, as long as it does not lose money, at least the comprehensive value of society has been reflected, and it is still cost-effective overall.

Plastic, rubber and metal waste, on the other hand, are further dismantled and sorted in more detail by people who have learned some professional knowledge.
