The project aims to promote the use of biochar technology to solve a large number of agricultural waste problems. It can not only effectively reduce the amount of waste removal and treatment costs, but with a positive impact on soil conditioner and mitigation of climate change. Combining resources of production, government, academia and citizen in this project, the team selected Guantian District as a demonstration field and set up low cost carbonization system. We choose the primary agricultural waste, water caltrop shell, in Guantian District as the research subject and try to find out good quality with inspection criteria biochar product and water caltrop vinegar should meet the following operating conditions: (1) the water content of water caltrop shell is between 14% and 16%. (2) the temperature of the combustion is above 950℃. (3) the burning time is more than 25min. During the project period, a total of 1,165 barrels of dried water caltrop shells were carbonized, 2.9 tonnes of carbon solidification and the net carbon dioxied reduction is about 10.2 tonnes. In addition, through the cross-cutting experts and scholars to guide and recommend the implementation of water, clean water, small pot experiment and field experiments. Current results from the experimental observations showed most of the beneficial plant growth and a few amount the negative effects of the experimental group after the addition of water caltrop shells biochar. The crop pot or field experiments are generally required to test 2 to 3 years, so the team need to follow-up long-term experiments to statistical analysis and verification if there is sufficient funds.
In order to let local citizens be able to produce biochar independently, the team trained 21 local volunteers and farmers by the carbonization furnace operating courses to make them understand the advantages of biochar and be familiar with furnace carbonization procedures. In cooperation with the three teaching units held biochar demonstration courses, so that students can understand the importance of environmental protection and the feasibility of re-use of agricultural waste, laying the foundation for future culture of outstanding researchers. In the latter part of the year, two small workshops will be held to enhance the public's understanding of environmental conservation and the proper use of biochar and by-products. At the end of the project, a large-scale workshop was held to showcase the bio-char production equipment, biochar
