Plast je skvel\u00fd vyn\u00e1lez<\/strong>, ale aj ve\u013ek\u00fd probl\u00e9m cel\u00e9ho \u013eudstva. U\u017e sa nad n\u00edm zamyslel sn\u00e1\u010f ka\u017ed\u00fd, kto sa aspo\u0148 trocha zauj\u00edma o \u017eivotn\u00e9 prostredie a environment\u00e1lny dopad \u010dloveka na svet.<\/p>\n

Niektor\u00e9 zdroje e\u0161te pred rokmi tvrdili, \u017ee plast tvor\u00ed a\u017e sedem percent hmotnosti v celkovom mno\u017estve komun\u00e1lneho odpadu a na Slovensku ho ka\u017ed\u00fd rok vyprodukujeme a\u017e 280 kilogramov na osobu. Za posledn\u00fdch p\u00e4\u0165 rokov v\u0161ak nepochybne tieto \u010d\u00edsla v\u00fdznamnej\u0161ie nar\u00e1stli.<\/p>\n

V pr\u00edrode je tak\u00fdto neorganick\u00fd plast takmer nezni\u010dite\u013en\u00fd<\/strong> a na jeho v\u00fdrobu je potrebn\u00e1 ropa, ktor\u00e1 je vy\u010derpate\u013en\u00fdm zdrojom. Aj keby na svete ost\u00e1valo ropy e\u0161te na cel\u00e9 desa\u0165ro\u010dia, je potrebn\u00e9 u\u017e teraz sa zam\u00fd\u0161\u013ea\u0165 nad nov\u00fdmi lep\u0161\u00edmi alternat\u00edvami plastov.<\/p>\n

Bolo teda len ot\u00e1zkou \u010dasu, kedy pr\u00edde niekto na to, ako plast nahradi\u0165 nie\u010dim ekologickej\u0161\u00edm. Rie\u0161en\u00ed sa pon\u00faka hne\u010f nieko\u013eko, ale nasledovn\u00fd vyn\u00e1lez patr\u00ed medzi tie, ktor\u00e9 maj\u00fa dobr\u00fa perspekt\u00edvu.<\/p>\n

\nPodarilo sa to vedeck\u00fdm pracovn\u00edkom\u00a0v laborat\u00f3riu <\/span>Brazilian Corporation of Agricultural Research<\/strong> and <\/span>nov\u00fd materi\u00e1l je vyroben\u00fd prekvapivo z ovocia a zeleniny. T\u00fdm z\u00e1rove\u0148 vyrie\u0161ili \u010fal\u0161\u00ed probl\u00e9m, ktor\u00fdm je nadmern\u00e9 mno\u017estvo odpadu z jedla. Na vytvorenie plastu pou\u017eili pap\u00e1ju, \u0161pen\u00e1t a paradajky<\/strong>, v\u010faka \u010domu m\u00e1 plast pre pr\u00edzna\u010dn\u00e9 zafarbenie. <\/span><\/p>\n

Samozrejme, v\u00fdrobn\u00fd proces nezah\u0155\u0148a iba nahromadenie surov\u00edn a jeho lisovanie – jedn\u00e1 sa o chemick\u00fd proces, n\u00e1ro\u010dnej\u0161ia metodika, \u010do stoj\u00ed za fin\u00e1lnym produktom.<\/span><\/p>\n

<\/div>\n Vyzer\u00e1 to skoro ako smoothie, ale po vysu\u0161en\u00ed sa z hmoty stane odoln\u00fd materi\u00e1l pou\u017eite\u013en\u00fd ako obal (zdroj: Brazilian Corporation of Agricultural Research)\n


\nZauj\u00edmav\u00e9 je, \u017ee aj takto vyroben\u00fd plast je flexibiln\u00fd, m\u00e1 v\u00fd\u017eivn\u00e9 vlastnosti z r\u00f4znych druhov plodov, vydr\u017e\u00ed pribli\u017ene tri mesiace a d\u00e1 sa dokonca pou\u017ei\u0165 aj ako hnojivo<\/strong>. Je takmer neuverite\u013en\u00e9, \u017ee sa tak\u00fdto organick\u00fd plast d\u00e1 aj zjes\u0165 a aj napriek tomu m\u00e1 dlh\u00fa trvanlivos\u0165<\/strong>. Vznikaj\u00fa tak celkom nov\u00e9 mo\u017enosti vyu\u017eitia.<\/span><\/p>\n

Ot\u00e1zkou do bud\u00facnosti u\u017e zost\u00e1va len zjednodu\u0161enie jeho v\u00fdroby nato\u013eko, aby dok\u00e1zal celkom nahradi\u0165 plasty, s ktor\u00fdmi sa stret\u00e1vame dnes. Na to bude potrebn\u00fdch minim\u00e1lne nieko\u013eko rokov a k nim bude potrebn\u00e9 pripo\u010d\u00edta\u0165 si aj obdobie, ktor\u00e9 bud\u00fa potrebova\u0165 ve\u013ek\u00ed v\u00fdrobcovia, aby technol\u00f3giu nasadili do \u0161tandardnej produkcie.<\/span><\/p>\n
