1. Kugwiritsa ntchito pachitetezo cha chilengedwe
Mu kafukufuku wa chilengedwe madzi anapeza kuti zinyalala tsiku ndi tsiku, ambiri anawagawa nayiloni, polyethylene, poliyesitala ndi zina zotero.Zinyalalazi sizingawonongeke kwathunthu m'madzi, ndipo kuchuluka kwake kukukulirakulira, kuvulaza kwawo kumawonekera.Ngati zida zowononga zikugwiritsidwa ntchito, zimatha kusinthidwa kukhala ma cell ang'onoang'ono omwe amapangidwa ndi ma enzymes achinsinsi, kenako amakhala carbon dioxide ndi madzi kudzera mu metabolism ya microbial.
2. Chidebe cha chakudya ndi ntchito zamakampani onyamula katundu
Zida zopangira ma biodegradable nthawi zambiri zimakhala ma polima owonongeka omwe amawonjezedwa ku filimu ya laminate kapena osakanizidwa mwachindunji ndi zinthu za laminate kuti apange filimu.Pazoyikapo, kafukufuku wochulukirapo ndikugwiritsa ntchito wowuma, mapadi, chitin ndi zinthu zina zachilengedwe za polima palokha kapena kusinthidwa kukhala zotengera zakudya ndi makanema onyamula.British PORVAIR kampani anapanga polyurethane chimanga wowuma pulasitiki katundu wa zipangizo zapadera, liwiro kuwonongeka, wowuma anawonjezera kuchuluka kwa 50%, mpweya ndipo akhoza kuwomberedwa mu filimu, chimagwiritsidwa ntchito ma CD chakudya.
3. Kugwiritsa ntchito ulimi
Zipangizo zosawonongeka zimagwiritsidwa ntchito kwambiri paulimi ngati mulch waulimi komanso zotengera pakukulitsa mbewu.Mulch waulimi wapangidwa mochuluka ndikugwiritsidwa ntchito kunyumba ndi kunja.Gulu lalikulu la biodegradable lomwe lili ndi N \ P \ K ndi zinthu zina za mankhwala linakonzedwa ndi Beijing Plastics Research Institute pogwiritsa ntchito polyethylene monga zopangira zopangira ndikuwonjezera photocatalyst ndi kuwonongeka.Zagwiritsidwa ntchito m'mafamu osiyanasiyana ndipo zapeza zotsatira zabwino.
4. Mu ntchito yachipatala
Zinthuzo zikamaliza ntchito yachipatala, nthawi zina zimatha kupangidwa ndi hydrolyzed kapena enzymolysis kukhala mamolekyulu ang'onoang'ono kuti atenge nawo gawo la kagayidwe kachakudya, kuti atengeke kapena kuchotsedwa ndi thupi la munthu.Zipangizo zowonongeka zakhala zikugwiritsidwa ntchito pa opaleshoni yam'mitsempha, opaleshoni ya mafupa, matrix otulutsa mankhwala mu vivo, ma sutures a absorbent ndi madera ena azachipatala.
