plastics: 污染 ring 境? this 锅我不背!

2020 year, new year 伊始, full world 就开启 “炼狱模式”, remove in most 受人瞩目 new 冠肺炎, large also for type more degree “暴击”.

from Africa 发起 蝗灾, to 澳洲漫天 large 火; from temperature degree already breakthrough 20℃ 南极, to day 利亚 神秘病毒......

人 type for large 自然造 formed 创伤, 都会以 certain types methods also to type upper, can amount 守恒一样, 索取, will need has 失.

in more in, also has 一项受 to 越 越 more 人 关注, that is: “ plastics 污染”.

1905 year, one-time 偶然 失误, 科学家“发明 ”酚 aldehyde resin, plastics from 此进入 人 type 视野; type active, production force 进步也进入 一 new 篇章.

plastics can more 样, can color color 斑斓, meanwhile especially resistant use, but also plastics processing 方便, easy large 规模 production , therefore plastics made parts versus ratio front metal or 者木头 made parts more 便宜, therefore application 越 越广泛.

however, a large amount of use rear, a large amount of waste material. plastics, already formed currently full 球 第一 large 污染. full year use 接近4 100 million plastics, one-time property plastics 就占 1.7 100 million 吨.

据调查, surface upper 几乎任何 方都 can to plastics in, in most deep large 洋底部, most 远 南极北极都不例 outer. plastics for ring and 海洋生 material belt/tape large 伤害.

而 for 自然 伤害, function to 人 身 upper, 据报道, in use type inner and lower water 里也发现 plastics micro 粒.

meanwhile, due to causes, a large amount of plastics waste in 太平洋 upper poly 集. this 太平洋 upper “第八 large 陆” full is plastics formed, its ratio France also large, versus 当于5 UK, 200 Shanghai 市, but also also in expand large.

environmental protection 人士甚至 in combined 国申请 formed new 国家: waste 群岛共 and 国(Garbage Islands Republic), USA front 副总统戈尔也申请 add formed is its 一员.

about/regarding plastics 误会

1959 year, packaging design 师斯滕·古斯塔夫·图林 design plastics packaging, 目 就 is ring 境.

因 is 当时 人们 a large amount of use bag, bag Raw Materials is 树木, therefore need a large amount of 树木, this for generate 危害. 基于此便诞生 既 light also resistant use plastics bag 子, this can use.

plastics therefore can by large application, is is from meet/satisfy certain 特定 目, different solutions competition degree 看, use plastics cost ( price ) more low, cost ( price )就 is for has consumption 资源代价 一 degree amount, cost more low, 意味 消 consumption 资源代价 more less, 否则 production plastics 厂家一定会亏 loss 经营不 lower, this is market this 看不见 手 how to 配置资源 use basic principle.

ratio 如, use 洗脸洗菜 plastics 盆问世 rear very fast substitute/replace iron 盆, is is its cost more low, ratio more high.

that plastics is how 污名化?

this is is 我们常常忽略 plastics another types cost, is plastics formed use make 命, it in 自然界之 rear, rear cost 并不像木材, metal this easy degradation material 质一样, cost comparison low 趋于零.

plastics by rear, can can for ring formed outer negative 担. this 不当遗弃造 formed outer negative 担, generate outer cost.

原, plastics manufacturing good, chemical property non stability, has year, 都不会 degradation, if 随意遗弃, 就会越堆越 more, ring method and 时处理, from is formed ring 境污染. is 乎, 人们就 怨 gas toward plastics, 他污名 is white 污染.

however, has waste material 乱扔, 不会造 formed ring 境污染呢?

plastics as is 人工发明 一 types material, 本身并无 good 恶, plastics products large 方便 人 type active, 本身并没 has 错, in plastics formed one-time use rear, for Post Consumer( use rear ) plastics how to 处置缺乏明确规划, 并随意丢弃. if combined 理规划, use rear plastics full can waste is 宝, or let plastics use rear 像木材, metal 一样容 easy degradation, more easy and melt is 一体.

how to solution plastics 污染

随 issues add heavy, type 也开始 手于 solution plastics issues.

第一, development biodegradable plastics. has 人想图方便, also is will use product use 完就扔, is development biodegradable plastics. main/primary is in plastics in biodegradable separation, make plastics by rear in ring lower can relatively fast degradation. its disadvantages is 不够经久 resistant use, need high 于常规 plastics cost.

can material degradation plastics formed and 叉子


第二, made plastics understanding and recycling method regulations . for main/primary use plastics made as electronics product and other prohibited 随意丢弃, must recycling as.

Europe waste electronics electrical equipment 指令(WEEE)


第三, improves recycled plastics application technology . will recycling waste plastics chemical or material methods, heavy new pelletizing utilizing.

plastics, is many has machine small separation material 质, through polymerization reaction to molecular weight is 几万甚至几十万 large separation 子.

from essence upper 看, plastics and 树木, type formed 一样, main/primary formed separation is carbon hydrogen combined material, is 我们说 has machine material . disadvantages is plastics property can stability, lifespan long, difficult 以进入生态循 ring.

但 is in long light, oxygen, wet degree and temperature degree function lower, plastics also is 会发生 aging degradation, from 而导致 property can decline. this made plastics again utilizing scope/range.

very more company in research how to recycling waste plastics heavy new use, again high property can 化, wide it application scope, from increase waste 弃资源 utilizing rate.

ratio 如DSM plastics company year in degree recycling nylon manufacturing 约2000吨 modified nylon plastics, due to waste nylon 网并进行清洗 cost currently also comparison high, therefore 售价并不 ratio use new material production modified nylon low.

Kumho day 丽也不例 outer, formed 立之初, 就 社会 responsibility in Company Culture 里. in 本世纪初, 就进行 a large amount of for can recycled material technology research and product development. through year 积累, 掌握 领先 will recycled plastics high property can 化 technology. development recycled PC/ABS, recycled PC/ABS无卤 flame retardant, recycled PC/PET无卤 flame retardant and other recycled material product solutions.

以Ecoblend®PC/PET KCA9351NH is 例, remove has 55.5% 消费 rear recycled (PCR) plastics, also can large large reduce product carbon 排放. 经测算, 每 use 1Kg types material can decrease/reduce 1.808Kg oxidation carbon 排放. related product formed is 客户营销 important and obtain 政府退税 based on.

can 说, plastics material is type 文明 一 艺术 product, plastics is formed ring 境污染 凶手. formed 污染, is 胡乱丢弃 plastics 我们每 人. utilizing good plastics, good plastics waste 弃, recycling, again utilizing, decrease/reduce waste plastics for ring 境 造 formed pressure, is solution plastics 污染 必由之路.
