论我国非粮生物质原料的非粮属性

能源安全与粮食安全既相互依赖又相互影响,发展生物质能源具有非常重要的战略地位,而非粮原料供应是生物质能源产业发展的最大瓶颈。非粮原则的本质是不能影响粮食安全,因而狭义的非粮生物质应定义为谷物籽粒以外的生物质。以谷物为粮食生产统计的国际口径,我国已基本实现了粮食自给,而且,据预测2029年当我国人口达到最多时,仍能保持基本的粮食安全。因此,谷物类籽粒毫无疑问不属于非粮生物质原料的种类,谷物籽粒类以外的农林业产品属于非粮生物质原料。豆类作物籽粒、薯类作物薯块、油料作物类籽粒和糖料作物含糖器官,属于受限制发展的非粮生物质原料种类;非食用的动植物产品及其他有机废弃物属于鼓励发展的非粮生物质原料种类。

Nature of non-food for the non-food biomass feedstock in China

Energy security and food security are both interdependent and interaction.Development of biomass energy is in an important strategic position,while the supply of non-food raw materials is the biggest bottleneck of the bio-energy industry.The nature of non-food is to develop biomass feedstock on the premise of food security.According to the international standard which takes cereal grains as food crop production,China has basically achieved self-sufficiency in grains.Moreover,studies predicted the country can still maintain the basic food security at a time when its population peaks in 2029.Therefore,while the agriculture and forestry products with the exception of cereal grains are non-food biomass feedstock,beans,tubers,oil seeds,and stems or roots rich in sugar are classified into the restricted non-food biomass feedstock.Non-edible animal and plant products including the residues and wastes are the category of encouraged non-food biomass feedstock.
