Dust sewage charges to levy a steel building or crack of the Road

    Recently, a lot of research in the field of well-known large V on the microblogging remind the public: the real causes of haze in fact is a consequence of a region or city integrated pollution, attracted more people are concerned about the burning of coal and oil and petrochemical pollution.

    Status: haze rule most overlooked part - dust

    This year's two sessions, the spokesman Fu Ying, when answering reporters' questions on environmental law firm, said the new "zero tolerance", "have teeth", where the pollution is not only mentioned in our traditional concepts familiar to industry emissions, waste pollution, the "zero tolerance" concept, an important part of the composition of the haze - dust, have a few days to get some attention to Beijing and other parts of the former two sessions, and the promulgation of the relevant statute of limitations city dust phenomenon.

    It is reported that Beijing since March 1 this year began implementing the sewage charges, and the main condition for the object is the construction site dust, the charging process is the first major re-assessment of differential charges, we understand that the construction site dust management to achieve excellent grades Standard, 1.5 yuan per kilogram; achieving the rank of standard 3 yuan per kilogram; non-compliance, 6 yuan per kilogram; public rental construction projects, disaster relief and rescue works and renovation of residential housing construction dust waive the charges.

    In fact, in most people's perception, and will consider the main source of haze is produced by burning coal smoke and car exhaust these two aspects, while the CAS survey in Beijing PM2.5 culprit has been described in published form One haze "culprit" fired only to 18%, the much-maligned automobile exhaust is only 4%, while the city has been neglected, but accounted for 15% of dust, until this year, "Beijing today," released the latest data show, "Green Beijing" construction site caused by dust and road dust accounted for about 30% of the total suspended particulate emissions.

    It is foreseeable that with Beijing dust collection fee purposes, especially in major cities suffered haze troubled city will usher in the era of engineering dust charges. As a representative of green building, compared with the previous concrete structures, steel buildings on dust control has a greater advantage.

    Future: energy saving building materials is the future trend of development

    Premier Li Keqiang in this year's government work report pointed out the need to lay the energy conservation and environmental governance battle. Environmental pollution is a risk of people's livelihood, the pain of the people, to iron-fisted control. This year, the intensity of carbon dioxide emissions to be reduced by more than 3.1%, chemical oxygen demand, ammonia emissions should be reduced by about 2 percent, sulfur dioxide, nitrogen oxide emissions to be reduced by about 3% and about 5%.

    Therefore, as a haze of construction dust core culprit will become this year's environmental governance "top priority." Data show that only a total carbon emissions, carbon emissions from traditional construction accounted for almost 50%, the proportion is much higher than the transportation and industrial sectors. In addition, since the average life expectancy of concrete building only 30 years, the concrete will be difficult to recover a huge security risk, and waste of resources, and other social problems, become constraints on urban development. Compared with concrete construction, with steel, metal as the main raw material of steel construction, the recovery of raw materials have obvious advantages. Data show that in the field of steel construction, steel recovery factor can reach 90%, steel and aluminum respectively 50% and 95%.

    . "From the whole life cycle, steel building construction waste will not produce basic" vice president Hangxiao Sui introduced the use of prefabricated steel building construction mode, only the construction work, no pollution; steel buildings from an average of 80 year building life point of view, even if they are removed, the steel construction also to higher recovery, to achieve recovery of steel, steel, architectural glass, aluminum, timber and other raw materials, to eliminate "construction waste Rising" from the roots. Sui further introduction to building demolition when, for example, steel construction of the main structural materials recovery above 90%, representing a 60% reduction in emissions of conventional concrete building rubbish.

    Moreover, steel buildings can also achieve "hidden steel in construction, steel hidden people" strategic reserves advantage. Statistics show that currently 95% of the British steel building construction steel has been effectively recovered; when the construction of roads in Japan, the workers will be laying a layer of high-quality steel in advance in the roadbed, and then perfused asphalt pavement.

    The dust fee collection in Beijing, making the original developers favored concrete structures faced with cost, energy-saving, environmental protection, such as multiple tests, which give Hangxiao steel enterprises represented a good opportunity for development. It is reported that Hangxiao newly developed "a combination of structural steel beams residential system", to further shorten the duration of steel construction, not only to reduce costs, but also improve the room rate and seismic performance in energy saving while providing better living experience.
