Isuku ikurikira ibisabwa ku ikorwa ry’ibikoresho by’ubuvuzi (nk’uko bivugwa kera). Ibikoresho byubatswe kugira ngo bishyirwe mu mubiri w’umuntu birumvikana ko bigomba kuba byujuje ibisabwa ku isuku yo mu rwego rwo hejuru. Hagomba kwitabwaho cyane gukumira ubwandu mu nganda z’ubuvuzi.
Ikibazo:
Uruganda rwo muri Amerika rukora ibikoresho by’ubuvuzi byinshi rukeneye kaseti yihariye. Isuku n’ubwiza ni byo bisabwa kuko ibikoresho byabyo bigomba gupfunyikwa mu cyumba cy’isuku iyo kaseti n’inyuma kugira ngo birindwe kwangirika. Bityo iyi kaseti yihariye igomba gukorwa na "zero". Ikirenze byose bisaba ubunyangamugayo 100% no kugumana isuku, ikaseti ikabungabungwa mu gihe cyo gupakira, kubika no kohereza.
Igisubizo:
Sinho yafashe iki kibazo. Itsinda rya Sinho ryita ku bushakashatsi n'iterambere rikora umuti wihariye wa kaseti y'umufuka ikoresheje ibikoresho bya Polyethylene Terephthalate (PET). Polyethylene Terephthalate ifite imikorere myiza cyane, imbaraga zayo zikubye inshuro 3-5 ugereranyije n'izindi mpapuro, nka Polystyrene (PS). Uburyo bwo kuba ifite ubucucike bwinshi bugabanya cyane ubucucike mu gikorwa cyo gukora, bigatuma "bur" iba impamo.
Byongeye kandi, dukoresha ikibaho cya pulasitiki cy'umukara cya santimetero 22 cya PP aho gukoresha icyuma gikingira impapuro, gifite irangi rirwanya static (ubushyuhe bwo hejuru busaba munsi ya 10^11 Ω) kugira ngo twirinde ibisigazwa by'impapuro no kugabanya umukungugu mu gihe cyo gupakira. Ubu, dukora ibikoresho birenga miliyoni 9.7 buri mwaka kuri uyu mushinga.
