- Bio-degradable straw flowerpots in production
After ten years of research, JAAS has successfully invented (created) the industrialization techniques for bio-degradable straw flowerpot production and the first production line was set up in Yongning Town, Pukou District in Nanjing. The grand launching ceremony for the production was held on March 28, 2012. More than 30 directors from Jiangsu Science and Technology Department, Nanjing Science and Technology Commission, Nanjing Agriculture Commission, and Pukou Government attended the ceremony.During the ceremony, Director Chang Zhizhou of the Institute of Agricultural Resources and Environment of JAAS introduced the R&D process and expressed his gratitude to the support given by all sectors involved. Director Chen Hongqiang of the Countryside Division of Jiangsu Science and Technology Department, JAAS Vice President Yu Wengui and Director Chang Zhizhou unveiled the plates for Pilot Base for Jiangsu Agricultural Wastes Processing Engineering Center and Pilot Base for Jiangsu Institute of Agricultural Resources and Environment.The bio-degradable straw flowerpots use the crop straws as raw materials and are made up through hot-pressing molding technology with the environment-friendly adhesives. Since 2002, the research has been supported by the grants from National High Technology Research and Development Program (863 Program), Jiangsu Agriculture Science and Technology Program, Jiangsu Agricultural Engineering Projects and Jiangsu Agricultural Science and Technology Innovation Fund, etc. The research has made innovations in straw pre-treatment, environment-friendly adhesives, hot-pressing molding technology and bio-degradation rules for straw flowerpots. Compared with ordinary flowerpots, the straw flowerpots are lower in cost but better in endurance, with 2 to 3 years for use. The straw flowerpots can keep its shape and color during the cultivation of ornamental flowers and plants. After the flowering period, the pots can still be reutilized or degraded with no residues.
The production is the first technical transfer of the research and was carried out by Nanjing Houchong Straw Products Company. The company invested 2.5 million yuan and set up 4 hot-pressing lines and 1 adhesives production line. The annual production amounts to 5 million pots (16cm) and receives 8 million yuan in benefits, with 720 tons of crop straws for consumption. The production provided a new technical approach for local crop straw high-value realization.
