| 摘要： | The manufacturers of asphalt plants are making enormous steps in developing new technologies for the market. Increasingly tough regulations mean that emissions from plants have to be strictly controlled in some key markets. Smoke, odour and dust emissions are now tightly regulated in some sectors, with plant firms also offering improved solutions for using RAP and producing warm asphalt. Meanwhile, the issue of alternative fuels for asphalt plants is another important factor for the sector. Green alternatives to existing fuel sources have been considered for some time, with new solutions having been developed that use renewable sources and are more sustainable. This issue has come to the fore in recent times due to the conflict in Ukraine following the illegal Russian invasion and the subsequent problems with regard to supplies of oil and gas from Russia as a result. Many asphalt plant makers have already developed contingencies for alternative fuels, with key advances for the sector now being highlighted and prioritised. According to the German firm Benninghoven, climate agreements and more stringent regulations issued by governments and authorities worldwide pose challenges for the asphalt industry with respect to reducing greenhouse gases such as CO_2 Owners of asphalt mixing plants have to reduce emissions to help secure the future of the plant site. The firm points out that when it comes to mixing asphalt in a cleaner and more sustainable way, changing from oil or coal dust to gas is a major step: Using natural gas or liquid gas can halve CO_2 emissions. |
