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 la burburin karo bakteeriyada ama noolaha kale, iyo "compost" ee warshadaha caagga ah waxaa lagu qeexaa inay awood u leedahay inay dumiso jawi aerobic ah oo lagu ilaaliyo xaaladaha heerkulka iyo qoyaanka gaarka ah ee la xakameeyey. biyo, xeryahooda aan noolaha lahayn iyo bayomass oo ah heer la siman
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. Dhab ahaantii, heerka xxx ee loo baahan yahay balaastikada loogu yeero compost ee qeexitaanka ASTM waa in ay tahay inay baaba'do isla heerka shay kale oo 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 ee East Lansing Michigan State University iyo lataliyaha sayniska ee machadka caagagga biodegradable.
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 caadi ah. Iyadoo soo-saareyaasha balaastikada biodegradable ee aerobic ay sheeganayaan in boorsooyinkooda dib loo warshadayn karo, dib-u-warshadeyaal badan oo caag ah ma aqbali doonaan sababtoo ah ma jirto daraasad muddo dheer ah oo ku saabsan wax soo saarka dib-u-warshadaynta. Caagagga Biodegradable (BPI) ayaa sheegay in qaababka wax lagu daro ee filimada oksaydhisku ay si weyn u kala duwan yihiin, taas oo soo bandhigaysa kala duwanaansho badan oo ku saabsan habka dib-u-warshadaynta.
