| − | + | We conducted a survey for both farmers and other citizens to get their views of the current treatment of straw and clean energy. We found that the phenomenon of burning straw still exists and utilization rate of it is particularly low. Besides, citizen's attitude toward clean energy is friendly but they are still not willing to use it. After understanding the basic situation of straw treatment and clean energy, we have communicated with professionals from Biogas Institute of Ministry of Agriculture and Rural Affairs to understand the current research progress in this field so as to improve our design. We got more information about obstacle in current research of reusing straw, as well as analysis of advantages and improvement in our project. After those above, we consulted biologist in our project to further optimize the pathway and experiment design in a more professional perspective. | |

| − | + | We carried on a series of analysis to get more information from our questionnaires. It was found that the amount of corn straw is produced at most, so it is reasonable that we choose corn straw as our researching direction. Moreover, it is obvious that the situation of treating the straw is still not very optimistic although the amount of incineration shows a decreasing tendency. From all above we come to the conclusion that the utilization of straw is really a problem that draws attention and we hope that we can alleviate this dilemma through our work this year. | |

| − | + | According to the above survey, it can be seen that people have fully realized that burning straw will pollute the environment, and most people believe that converting straw into clean energy is the best way to deal with it. We find that citizens have a strong preference for clean energy, but their use intention is not high. Improving the convenience of the use of clean energy can increase the tendency of citizens to use clean energy. When asked if people would accept genetically engineered bacteria, more than half said they would, and most said it would improve the situation. These results led us to determine the use of bacteria to degrade straw and produce clean energy. | |

| − | We | + | We interviewed Dr. Liangwei Deng, a professor of biogas engineering. He explained the current status of agricultural residues in great detail to us, and told us that straw is the largest untapped carbon source at present. In the field of agricultural waste bioenergization, producing biogas is the most mature technology, but there are still some problems, such as the short life of biogas digesters, safety problem, high cost of centralized transportation of agricultural waste, and difficulty in handling waste liquids. At present, the most common use of biogas is to generate electricity, followed by fuel cells. We consulted him about the situation of agricultural waste treatment and introduced our project of this year. |

1. OverviewWe conducted a survey for both farmers and other citizens to get their views of the current treatment of straw and clean energy. We found that the phenomenon of burning straw still exists and utilization rate of it is particularly low. Besides, citizen's attitude toward clean energy is friendly but they are still not willing to use it. After understanding the basic situation of straw treatment and clean energy, we have communicated with professionals from Biogas Institute of Ministry of Agriculture and Rural Affairs to understand the current research progress in this field so as to improve our design. We got more information about obstacle in current research of reusing straw, as well as analysis of advantages and improvement in our project. After those above, we consulted biologist in our project to further optimize the pathway and experiment design in a more professional perspective.

2. Supporting ResearchSurvey for farmersWe released a series of questionnaires for farmers to get more information on production and treatment of straw. The total number of questionnaires collected by farmers reached 231, of which 214 were valid questionnaires; we collected the questionnaire in the way of face to face interview as well as internet etc.
We carried on a series of analysis to get more information from our questionnaires. It was found that the amount of corn straw is produced at most, so it is reasonable that we choose corn straw as our researching direction. Moreover, it is obvious that the situation of treating the straw is still not very optimistic although the amount of incineration shows a decreasing tendency. From all above we come to the conclusion that the utilization of straw is really a problem that draws attention and we hope that we can alleviate this dilemma through our work this year.Survey for citizensWe also conducted a questionnaire for citizens to investigate their attitude toward clean energy. The number of citizens reached 531, of which 516 were valid questionnaires.
According to the above survey, it can be seen that people have fully realized that burning straw will pollute the environment, and most people believe that converting straw into clean energy is the best way to deal with it. We find that citizens have a strong preference for clean energy, but their use intention is not high. Improving the convenience of the use of clean energy can increase the tendency of citizens to use clean energy. When asked if people would accept genetically engineered bacteria, more than half said they would, and most said it would improve the situation. These results led us to determine the use of bacteria to degrade straw and produce clean energy. -
3. Connection with relevant instituteIn order to investigate and understand more current status of agricultural waste treatment and clean energy, we visited the Biogas Institute of Ministry of Agriculture and Rural Affairs and communicated with related experts.They explained the situation of agricultural waste treatment and their current research progress to us. From our conversations with them, we learned more about current state in dealing with straw, as well as the development and problems in producing bioenergy. Based on our interview, we conducted a more comprehensive evaluation of our project and made improvements on it.With Dr. Liangwei DengWe interviewed Dr. Liangwei Deng, a professor of biogas engineering. He explained the current status of agricultural residues in great detail to us, and told us that straw is the largest untapped carbon source at present. In the field of agricultural waste bioenergization, producing biogas is the most mature technology, but there are still some problems, such as the short life of biogas digesters, safety problem, high cost of centralized transportation of agricultural waste, and difficulty in handling waste liquids. At present, the most common use of biogas is to generate electricity, followed by fuel cells. We consulted him about the situation of agricultural waste treatment and introduced our project of this year.- How do you think of the current status of agricultural waste treatment?- The situation of existing processing methods are not so good. burning straw is still popular in many areas in China, causing very serious air pollutions. To the field will breed pests and diseases, leading to carbon to nitrogen ratio imbalance in the land. Other methods such as silage, as a raw material for mushroom cultivation, etc., could not solve the problem of excessive agricultural waste. So I think it is excellent to treat it using biological ways.- How do you think of our project?- Although the current biogas digesters have been relatively mature and promoted, its limitations are also obvious. Biogas has a limited range of applications and cannot meet many application requirements. So I am willing to see the generation of other types of clean energy, just like hydrogen and butanol in your project.

He has published 1 monograph and 1 editorial, and participated in the preparation of 9 professional books; 9 national invention patents and 3 utility model patents. At present, the Biogas Research Institute of the Ministry of Agriculture is engaged in the research, design and commissioning of wastewater, solid waste treatment and biogas engineering, and is the leader of China's biogas project [1].With Dr. Mingxiong HeWe talked with Dr. Mingxiong He.
