近段 time, plastics positive environmental protection 风潮 巨 large impact, is difficult degradation to ring belt/tape large negative 担, 各国政府纷纷出台严厉 environmental protection measures in and 禁塑, plastics packaging industry sheet/slice 愁云惨雾. 不, 近期一 research formed 果, also let industry to dark 花明 春天.
基于 above analysis, in large 谢毅院士课题组 in 模拟 自然 ring lower, light 诱导C-C裂 understanding and mechanism, will one-time property plastics bag, box/case, film and other plastics waste in add other agent lower formed 功转化 is high can amount density C2燃 material. in oxidation 二铌（Nb2O5） catalytic function lower, add water, to cationic light, in gas in, need 40 h, plastics polyethylene (PE) can 100%转化 is CO2, rear this CO 2 in light lower by also is has value CH3COOH（如图1 示）.
图1. in 模拟自然 ring lower, waste plastics through reaction to C2燃 material 示意图.
this research through C-C裂 understanding and combined mechanism formed will waste plastics formed material, is solution white 污染开辟 new 途径.
图2. in 模拟自然 ring lower various plastics light is C2燃 material. research research pure PE, PP and PVC in 模拟自然 ring in light active property, 发现PE, PP and PVC in light catalytic function lower consumption 时40 h, 60 h and 90 h就 can 100％转化 is CO 2, CO 2 output/production volume increase, rear to value, generate and solvent understanding CO 2总摩尔数几乎 and PE, PP or PVC in carbon 摩尔数 versus and other, plastics full by light degradation is CO2. 综观 full decrease policy, degree most fast 莫 于直接 prohibited use plastics bag Africa 国家们. 厄立特里亚早 in 2005 year comprehensive use plastics bag. other also 包括坦桑尼亚（2006）, dry 达（2007）, 卢旺达（2008）, 摩洛哥（2016 year ）, inner add 尔（2016）, 索马里兰（2017 year ） and 肯尼亚（2017） and other 国, is comprehensive use plastics bag, is prohibited manufacturing, and use plastics bag, 违规甚至 also has 刑责 处罚. currently Africa 54 国家 in, has 34 国家 has related policy. in large 陆, France from 2020 year use 抛弃式 plastics tool, and Germany prohibited 胶囊咖啡. day front 宣布 2030 year need recycling or heavy use inner plastics packaging. UK is 喊出 25 year inner use plastics bag, bottle, plastics tube/pipe and other use product. USA currently has add comprehensive use plastics bag, its 余城市需付费购买纸 bag or plastics bag, 另包括纽约 and other 数十 城市禁 use 保丽龙. in 亚洲, Taiwan 限塑令 scope/range expand large, 南亚各国 more is more let. add is full 球第一, in 2002 year comprehensive use plastics bag! degree in 2016 year prohibited use thick degree small 于 0.05 公厘 plastics bag, 斯里兰卡也 prohibited plastics bag, plastics and plastics 杯. Southeast Asia 各国, has scope/range large small and other policy, 例如: 缅甸 首都仰 light prohibited manufacturing, and plastics bag; Malaysia in year 也宣布联邦直辖区（吉隆坡, nano 闽, 布城） prohibited use generally plastics bag, product packaging use 由商家 negative 担. other 区, Japan 则宣布 2020 year 起, has 零售商店都 prohibited provide plastics bag, China in 2008 year prohibited provide plastics bag, prohibited manufacturing, and use thick degree small 于 0.025公厘 plastics bag. 圣路 easy 斯华盛顿 large Liberty Vittert also 算 一笔账. 2018 year generate plastics, can 装满 72 万 100 million large material bag. large material bag can lower 31 plastics bottle, plastics bottle manufacturing cost is 3.25 美 separation, therefore 一 装满空 plastics bottle material bag value is 31 x 3.25 = 100.75 美 separation, and other 于 1 美元. is 说, 2018 year generate 72 万 100 million bag plastics waste, production cost is 72 万 100 million USD. 如此 large industry, if can to plastics material solutions, China plastics packaging industry outlook/prospects also 变 妙不 can 言!
