1、 Eliminate open burning and reduce emissions from the source
Burning straw in the open air will instantly release a large amount of pollutants, including:
Particulate matter: It is the main component that forms haze.
Harmful gases: such as sulfur dioxide, nitrogen oxides, carbon monoxide, etc.
Strong greenhouse gases: methane, black carbon, etc.
By concentrating and standardizing the conversion of straw into energy, straw gas power generation completely eliminates the scattered and disorderly burning behavior, directly reducing the emissions of all the pollutants mentioned above from the source. The effect on improving regional air quality, especially in summer and autumn seasons, is evident.
2、 Realize carbon cycle and help achieve ‘carbon neutrality’
Straw gas power generation belongs to the utilization of biomass energy, and its biggest environmental protection feature is “carbon neutrality”. During the growth process, plants absorb carbon dioxide from the atmosphere through photosynthesis and fix it in their bodies. When these straw are used for gasification power generation, the carbon dioxide released is essentially the CO ₂ absorbed by plants during growth. Therefore, there will be no net increase of carbon dioxide into the atmosphere throughout the entire lifecycle.
This is fundamentally different from burning fossil fuels (coal, oil, natural gas), which release carbon stored in the Earth’s crust for billions of years in a short period of time, leading to a sharp increase in atmospheric carbon dioxide concentration. Therefore, vigorously developing straw gas power generation is one of the important paths to replace fossil fuels and achieve China’s “carbon peak and carbon neutrality” goals.
3、 Improving soil and water environment
In addition to air pollution, straw burning can also directly burn surface microorganisms, damage soil structure, and lead to a decrease in soil fertility. And after straw is collected for power generation:
Protecting soil ecology: Avoiding the destruction of soil by burning.
Reduce eutrophication of water bodies: Under the erosion of rainwater, the nitrogen, phosphorus, and other elements decomposed from indiscriminately piled up straw will enter the water body, causing eutrophication. Centralized processing avoids this problem.
Provide high-quality potassium fertilizer: The gasified plant ash can be returned to farmland to supplement the potassium element in the soil and form a virtuous material cycle.
4、 Promote comprehensive improvement of rural environment
The straw gas power generation project requires the establishment of a standardized collection, storage, and transportation system, which promotes the establishment of a cleaner and more orderly waste management mechanism in rural areas. The operation of the project itself can also create employment opportunities and promote the transformation of rural areas from “dirty, messy and poor” to “industrial prosperity and environmental beauty”.
Conclusion:
The environmental value of straw gas power generation far exceeds its energy value. It is not just a generator, but also a comprehensive environmental protection project that integrates “pollution control, carbon reduction, resource recycling, and environmental improvement”. Promoting straw gas power generation is a manifestation of our responsibility to future generations and a practical effort to build a beautiful home where we can see mountains, water, and remember our hometown.
