Chikho cha ayisikilimu chapamwamba kwambiri, chopanda chilengedwe, chikho cha supu ya yogati yozizira, chikho cha supu ya ayisikilimu yotayidwa

Makapu a chimanga ovundaamapangidwa ndi pulasitiki yotha kuwola. Mapulasitiki otha kuwola ndi mbadwo watsopano wa mapulasitiki omwe amatha kuwola komanso kupangidwa manyowa.

Kawirikawiri amachokera ku zinthu zongowonjezedwanso monga starch (monga chimanga, mbatata, tapioca etc), cellulose, soya protein, lactic acid etc., si zoopsa/zoopsa popanga ndipo zimawolanso kukhala carbon dioxide, madzi, biomass etc. akapangidwa manyowa. Mapulasitiki ena opangidwa manyowa sangachokere ku zinthu zongowonjezedwanso, koma m'malo mwake amachokera ku mafuta kapena mabakiteriya kudzera mu njira yopangira tizilombo toyambitsa matenda.

Pakadali pano, pali mitundu yosiyanasiyana ya ma resin apulasitiki opangidwa ndi manyowa omwe amapezeka pamsika ndipo chiwerengerochi chikukwera tsiku lililonse. Zinthu zopangira mapulasitiki opangidwa ndi manyowa omwe amagwiritsidwa ntchito kwambiri ndi chimanga cha chimanga, chomwe chimasanduka polima yokhala ndi zinthu zofanana ndi zinthu zapulasitiki wamba.
