1. Ingxowa yokubola kwezinto eziphilayo，Iingxowa zokubola kwezinto eziphilayo ziingxowa ezikwaziyo ukubola ziintsholongwane okanye ezinye izinto eziphilayo. Zimalunga nama-500 eebhiliyoni ukuya kwi-1 trillion iingxowa zeplastiki ezisetyenziswa minyaka le. Iingxowa zokubola kwezinto eziphilayo ziingxowa ezikwaziyo ukubola ziintsholongwane okanye ezinye izinto eziphilayo. Zimalunga nama-500 eebhiliyoni ukuya kwi-1 trillion iingxowa zeplastiki ezisetyenziswa minyaka le.
2. Yahlula phakathi "okubolayo" kunye "nokugquma"
Ngokwesiqhelo, igama elithi "biobolitable" linentsingiselo eyahlukileyo kune-compost. I-biobolitable ithetha nje ukuba izinto zinokubola ziibhaktheriya okanye ezinye izinto eziphilayo, kwaye "umquba" kwishishini leplastiki uchazwa njengokukwazi ukubola kwindawo engqongileyo egcinwe kubushushu obuthile obulawulwayo kunye neemeko zomswakama. I-Compospost kukukwazi ukubola kwintsimi ye-compost, okwenza izinto zingabonakali kwaye zibole zibe yi-carbon dioxide, amanzi, iikhompawundi ezingaphiliyo kunye ne-biomass ngesantya esihambelanayo
Ukufakwa kwezinto "ezingabonakaliyo" kwasusa imveliso yokugqibela ekubeni ithathwe njenge-compost okanye i-humus, eyi-organic material kuphela. Enyanisweni, umgangatho we-xxx ofunekayo ukuze iplastiki ibizwe ngokuba yi-compost phantsi kwenkcazo ye-ASTM kukuba kufuneka inyamalale ngesantya esifanayo nesinye into umntu asele esazi ukuba i-compost phantsi kwenkcazo yendabuko. Iingxowa zeplastiki zinokwenziwa nge-polymer yeplastiki eqhelekileyo (oko kukuthi, i-polyethylene) okanye i-polypropylene kwaye zidityaniswe ne-additive ebangela ukubola kwe-polymer (i-polyethylene) ize ibole ngenxa yoko.
3. Izinto zengxowa ebolayo
ziqinile kwaye zithembekile njengeengxowa zemveli (ikakhulukazi i-polyethylene). Iingxowa ezininzi zenziwe ngephepha, izinto eziphilayo, okanye i-polyhexanolactone. "Uluntu lubona ukuba ukubola yinto engummangaliso," nangona eli gama lisetyenziswa kakhulu, ngokutsho kukaRamaniNarayan, injineli yeekhemikhali kwiYunivesithi yase-East Lansing Michigan State kunye nomcebisi wesayensi kwi-Institute for Biodegradable Plastics." Eli lelona gama lisetyenziswa kakhulu kwaye lisetyenziswa gwenxa kwisichazi-magama sethu. Kwi-Greater Pacific Waste Area, iplastiki ebolayo iyaqhekeka ibe ziingceba ezincinci ezinokungena ngokulula kuluhlu lokutya ngokutyiwa.
4.Ukuphinda kusetyenziswe iingxowa ezibolayo.
Inkunkuma ekwizityalo idla ngokuphinda isetyenziswe, kodwa kunzima ukuyihlela nokuyiphinda isetyenziswe emva kokusetyenziswa. Iipolymers ezisekelwe kwi-bio zinokungcolisa ukuphinda isetyenziswe kwezinye iipolymers eziqhelekileyo. Ngelixa abavelisi beplastiki ezinokubola nge-aerobic besithi iingxowa zabo zinokuphinda zisetyenziswe, uninzi lwabaphinda basebenzise iifilimu zeplastiki abayi kuzamkela kuba akukho phando lwexesha elide malunga nokuba kunokwenzeka na iimveliso ezinokuphinda zisetyenziswe ezi zinto zongeziweyo. Ukongeza, i-Institute for Biodegradable Plastics (BPI) ithe ukwakheka kwezongezo kwiifilimu ezi-oxidized kwahluka kakhulu, nto leyo evelisa umahluko omkhulu kwinkqubo yokuphinda isetyenziswe.
