1.Biodegradation bag，Iibhegi zeBiodegradation ziingxowa ezikwaziyo ukuboliswa ziibhaktheriya okanye ezinye izinto eziphilayo. Malunga nama-500 eebhiliyoni ukuya kwi-1 yeetriliyoni zeengxowa zeplastiki zisetyenziswa minyaka le. Iingxowa ze-Biodegradation ziingxowa ezikwazi ukuboliswa ziibhaktheriya okanye ezinye izinto eziphilayo. Malunga nama-500 eebhiliyoni ukuya kwi-1 yetriliyoni yeengxowa zeplastiki ezisetyenziswa minyaka le.
2.Ukwahlula phakathi kwe "biodegradable" kunye "compostable"
Ngokwesiqhelo, igama elithi biodegradable linentsingiselo eyahlukileyo kune-compost.I-biodegradable ithetha nje ukuba izinto zinokubola ngebhaktheriya okanye ezinye izinto eziphilayo, kwaye "umgquba" kwishishini leplastiki uchazwa njengokwazi ukubola kwimeko ye-aerobic egcinwe kwiimeko ezithile zokushisa kunye nokufuma. amanzi, iikhompawundi ze-inorganic kunye ne-biomass ngesantya esihambelanayo
Ukufakwa kwe "inorganic material" kwakungabandakanyi imveliso yokugqibela ekuthathweni njenge-compost okanye i-humus, eyona nto i-organic material.Enyanisweni, umgangatho we-xxx ofunekayo ukuze iplastiki ibizwe ngokuba ngumgquba phantsi kwenkcazo ye-ASTM kukuba kufuneka zinyamalale kwizinga elifanayo njengenye into esele iyazi ukuba i-compost phantsi kwenkcazo yendabuko. Iingxowa zeplastiki zingenziwa kwipolymer yeplastiki eqhelekileyo (oko kukuthi, i-polyethylene) okanye i-polypropylene kwaye ixutywe kunye ne-additive ebangela ukuthotywa kwe-polymer (i-polyethylene) kwaye emva koko i-biodegradable ngenxa.
3.Impahla yengxowa enokubola
yomelele njengoko iqinile kwaye ithembekile njengeengxowa zemveli (ingakumbi i-polyethylene).Iingxowa ezininzi zenziwe ngephepha, izinto eziphilayo, okanye i-polyhexanolactone. "Uluntu lubona i-biodegradable yinto enomlingo," nangona igama lisetyenziswa ngokubanzi, ngokutsho kukaRamaniNarayan, injineli yeekhemikhali e-East Lansing Michigan State University kunye nomcebisi wesayensi kwi-Institute for Biodegradable Plastics.
4.Ukurisayikilishwa kweengxowa ezinokonakala.
Inkunkuma engaphakathi kwesityalo iyakwazi ukuphinda isetyenziswe, kodwa kunzima ukuyilungisa kwaye isetyenziswe kwakhona emva kokusetyenziswa. (BPI) yathi ukuqulunqwa kwezongezo kwiifilimu ezine-oxidized zihluka ngokubanzi, ezizisa ukuguquguquka okungakumbi kwinkqubo yokubuyisela kwakhona.
