Re: Ji'nan 12 construction waste dumps will be filled next year. Where is the recycling card?
eat construction waste to spit out recycled aggregate
9 a.m., in the big Han Valley District green city place B8 block, a large mobile crushing equipment in Shandong Ming ran company is spectacular. Excavator excavate the building garbage and put into the mobile crusher, first broken,
sieve, the sieve out of the aggregate according to the size of the four conveyor belts on the ground, some of the aggregate size is only 5mm, some to 100mm, within a few minutes, large construction waste becomes fine particles. "
" recycled aggregate can be directly filled with building grooves and municipal roads, and can be processed into bricks, concrete or dry mixed mortar through deep processing. It can be reapplied to construction, and can realize the
source and reuse of construction waste 100%. " Shandong Ming ran recycling resource utilization Co., Ltd. is in charge of the ship. "Because of the light weight of the recycled brick and the high water absorption rate, it is especially suitable for the construction of the sponge city. The price is about 20% lower than that of the traditional product market."
according to the introduction, Shandong Ming Ran is one of only a few companies in our city to reuse construction waste. In 2013, they bought more than 900 million yuan from Belgium to buy construction waste treatment equipment, and bought a shovel, fog artillery and other supporting equipment, a total of more than 1000 yuan.
"at present, the company has the corresponding technology, mainly in the" import "and" export "problems. "Entrance" is the centralized transportation of construction waste, building building site is not good to find 'export' that is to build
construction of garbage production products sales channels are not clear, for us, there is still a lack of policy support. Say to the ship.
is very severe -
12 construction garbage dumps will be filled with
next year to know from the city city administration that the amount of construction waste in our city is about 30 million cubic meters per year, some of which are used to backfill the site and greening, and more than 1/3 of construction waste is transported to the dumping plant for landfill. As the vast majority of construction waste has not been treated, the opencast storage not only occupies the land, pollute the water and air, but also affects the city's capacity, and there are many hidden dangers.
"at present, there are 12 dump dumping sites around our city. If we do not build a new dumping ground, we will fill the new dumping ground next year and need to go further away from the city if the new dumping speed is not built. On the one hand, the surrounding areas are developing. It is very difficult to find large dumping sites. On the other hand, transportation costs will increase correspondingly, and the pressure of muck transport units will increase and enthusiasm will be reduced. The City Administration Bureau, the relevant person in charge, said. Faced with the current grim situation, this small construction waste utilization mode has become one of the breakthrough points.
is very embarrassing -
building garbage recycling needs "people pick up firewood"
although this machine can solve a part of the problem of building garbage, but because of lack of policy support, lack of implementation standards, they have developed more extensive, facing a lot of problems. "The embarrassing thing is that at present, the system of building waste resource utilization in our city is not perfect, the development of this kind of small enterprise is more difficult, even the competent units are not." "We will try to support the industry in the next step and improve the utilization of resources on the basis of a gradual standard, so that it can reduce a large amount of pressure at the end," said the director of the City Management Bureau.
of course, the development of the industry is inseparable from the support and participation of all relevant departments. "If we can build a processing line in the existing dumping ground, one head of digested waste and one end of the production of products can not only delay the time that the dump is filled, but also produce a part of the benefit." "But the power of only one department is not enough. It needs a lot of departments to cooperate with each other and support each other so that building waste can be turned into a treasure."
