Bacaha biodegradation ， bacaha biodegradation waa bac awood u leh in ay bakhtiiyaan bakteeriyada ama noolaha kale. Qiyaastii 500 bilyan ilaa 1 trillion bacaha caag ah ayaa la isticmaalaa sannad kasta. Bacaha bayoolajiga waa bac awood u leh in ay burburiyaan bakteeriyada ama noolaha kale. Qiyaastii 500 bilyan ilaa 1 tiriliyan bac ayaa la isticmaalaa sannad kasta.
2. Kala saar "biodegradable" iyo "compostable"
Ereyga caadiga ah, ereyga biodegradable wuxuu leeyahay macne ka duwan compost.Biodegradable si fudud macnaheedu waa in walxaha ay burburin karaan bakteeriyada ama noolaha kale, iyo "compost" ee warshadaha caagga ah waxaa lagu qeexay awoodda ay u leedahay inay ku dumiso jawi aerobic ah oo lagu hayo si gaar ah. Xaaladaha heerkulka iyo qoyaanka la xakameeyey
Ku darida "walxaha aan noolaha ahayn" waxay ka reebtay alaabta kama dambaysta ah in loo tixgeliyo inay yihiin compost ama humus, taas oo ah walxo dabiici ah oo kaliya. Runtii, heerka xxx ee looga baahan yahay balaastiga loogu yeero compost ee qeexitaanka ASTM waa in ay tahay inay isla baaba'aan. u qiimee sida shay kale oo qofku hore u yaqaan inuu compost hoos yimaado qeexitaan dhaqameed. Bacaha balaastikada ah waxaa laga samayn karaa polymer caag ah oo caadi ah (ie, polyetylen) ama polypropylene waxaana lagu qasi karaa wax lagu daro oo sababa xaalufka polymer (polyethylene) ka dibna biodegradable sabab u ah.
3.Waxyaabaha loogu talagalay bacda noolaha
xoog leh oo adag oo la isku halayn karo sida bac dhaqameed (badanaa polyetylen). "Dadweynuhu waxay arkaan biodegradable waa shay sixir ah," inkastoo ereyga si weyn loo isticmaalo, sida uu qabo RamaniNarayan, injineer kiimikaad oo ka tirsan Jaamacadda Bariga Lansing Michigan State iyo lataliyaha sayniska ee machadka caagagga biodegradable." Tani hadda waa tan ugu badan ee la isticmaalo. iyo kelmad si khaldan loo isticmaalo oo ku jirta qaamuuskeena. Aagga Qashinka Baasifigga ee Weyn, balaastiig-biodegradable waxay u kala qaybsantaa qaybo yaryar oo si fudud u geli kara silsiladda cuntada iyadoo la isticmaalo.
4.Dib u warshadaynta bacaha noolaha.
Qashinka dhirta sida caadiga ah dib ayaa loo warshadeyn karaa, laakiin way adag tahay in la kala saaro oo dib loo warshadeeyo ka dib isticmaalka. Polymers-ku salaysan bio waxay wasakhayn karaan dib-u-warshadaynta polymers kale oo caan ah. Halka kuwa soo saara caagadaha aerobic biodegradable ay sheeganayaan in boorsooyinkooda dib loo warshadeyn karo, filimo badan oo caag ah. dib u warshadeeyayaashu ma aqbali doonaan sababtoo ah ma jirto daraasad dheer oo ku saabsan suurtogalnimada alaabta dib loo warshadeyn karo oo ay ku jiraan waxyaalahan lagu daro. Intaa waxaa dheer, Machadka Bacaha Biyodegradable (BPI) ayaa sheegay in qaababka wax lagu daro ee filimada oksaydhisku ay aad u kala duwan yihiin, taas oo soo bandhigaysa kala duwanaansho badan. habka dib u warshadaynta.
