As we all know, in the catering industry, catering enterprises will not use catering waste oil (commonly known as waste oil) for the second time. On the one hand, it is because the waste oil of catering can not increase the taste of catering, and even affect the health of consumers. On the other hand, it is because all major cities are establishing waste oil treatment systems, thus reducing the waste oil that catering enterprises can't get reasonable treatment.
Today, Chinese scientists use waste oil for the second time. Instead of directly adding gutter oil to meals, they use cooking technology and purification technology to convert gutter oil into aviation fuel. In this way, the utilization rate of waste oil can be further improved, and the cost of space fuel can also be reduced.
The first reason: related technologies cannot be popularized on a large scale. Although ordinary people can master a very simple method of turning waste into treasure, for scientists, purification technology needs to be applied to a large number of instruments and related data. As far as the current situation is concerned, it is difficult to promote the relevant programs on a large scale. In the laboratory stage, scientists have repeated experiments many times to obtain the most accurate experimental results. In real life, ordinary residents can't master technology. How can we turn waste into treasure on a large scale?
The second reason: some waste materials are still available. Take waste books and paper as an example. Professional organizations will use waste paper to complete the production process of new books. In large-scale book manufacturing factories, most of the purchased waste paper will be crushed and bleached. Then, the staff will turn the treated waste paper into tissue paper again, thus completing the printing process. In fact, most of the waste materials still have very good secondary utilization value, so people call the waste materials treasure in the wrong place.
Generally speaking, although every family produces garbage every day, unreasonable garbage disposal methods will cause environmental pollution. Ordinary residents can try to use simple methods to turn waste into treasure, and further improve the secondary use value of goods.
