Endabirwamu erudde ng’efuga akatale k’okupakinga omwenge, naye si y’engeri yokka. Nga obwetaavu bw’akatale k’ensi yonna obw’enjawulo bweyongera okubeera obw’enjawulo, omuwendo-obulungi, n’engeri y’ebintu, okulonda ebintu by’eccupa z’omwenge kifuuse ensonga enkulu mu mulimu gw’ebyobusuubuzi mu nsi yonna.
Eccupa z’endabirwamu ez’ekinnansi, n’eby’obugagga byazo ebirungi ennyo eby’okuziyiza (nga oxygen n’okukuuma ekitangaala) n’endabika ey’omutindo, bisigala nga bye bisinga okwettanirwa ku wayini eziri waggulu-end. Naye, obuzito bwazo bwongera ku nsaasaanya y’entambula (okusinziira ku bitundu nga 15%-20% ku nsaasaanya yonna ey’okutambuza ebintu) n’okufulumya kaboni (nga 0.8- 1.2 ttani za CO2 buli ttani ekoleddwa), ekireetera abamu ku bafulumya ebweru okufuuka endabirwamu ezitazitowa oba ebikozesebwa ebirala. Okugeza, "eccupa y'endabirwamu egonvu eya ultra," ebadde efuuse ey'ettutumu mu katale k'e Bulaaya mu myaka egiyise, esobola okukendeeza ku buzito ebitundu 20%-30%, ekikendeeza nnyo ku ssente z'okutwala ebintu ku nnyanja mu nnyanja. Naye kino kyetaagisa enzikiriziganya wakati w'amaanyi g'okunyigiriza n'okwagala kw'abaguzi okukola "omukolo gw'okuggulawo eccupa."
Nga zivugibwa obutonde bw’ensi, obuveera bwa PET (polyethylene terephthalate) n’ebibbo bya aluminiyamu bye biva mu kukula. Eccupa z’ebisolo by’omu nnyumba zizitowa emu yokka-eights nga endabirwamu, ekizifuula ennungi ennyo okutambuza. Okwongerako layeri ya oxygen barrier layer kiyinza okwongera ku bulamu bwa wayini okutuuka ku 12-emyezi 18, ekibafuula abasaanira okutunda ebweru wayini z’oku mmeeza ez’ebbeeyi ezigendereddwamu abaguzi abato. Ebibbo bya aluminiyamu, 100% ebisobola okuddamu okukozesebwa n’okumenyaamenya-ebiziyiza, bilabye okuyingira kwazo mu North America okufuluma-okukozesebwa awaka kweyongera okukula buli mwaka. Kyokka, akabi k’obuwoomi obw’ekyuma kyetaagisa enkola enkakali ey’okusiiga munda.
Ekirala, obuwangwa "okuddamu okukozesa" obucupa bw'endabirwamu mu butale obukyakula nga Southeast Asia (okukozesa eccupa etaliimu kintu kyonna ng'ebintu eby'okwewunda) nabwo bukwata ku kusalawo kw'ebintu. Kkampuni z’ebyobusuubuzi ez’ebweru zeetaaga okulonda mu ngeri ekyukakyuka okugatta ebintu okusinziira ku mateeka agafuga akatale (nga EU’s recycling labeling requirements for plastic packaging), abaguzi okwettanira, n’ebisale by’okugaba ebintu. Mu biseera eby’omu maaso, ebintu ebiyiiya nga BIO-ebiwujjo ebisinziira ku biwujjo biyinza okufuuka okumenyawo enjawulo y’okuvuganya.
