IV. Puas yog daim ntawv ice cream khob ua tau raws li European ib puag ncig cov qauv
1. Cov kev cai ib puag ncig rau cov khoom ntim khoom noj hauv Europe
Cov European Union muaj cov cai nruj ib puag ncig rau kev siv cov khoom ntim khoom noj. Cov no tuaj yeem suav nrog cov hauv qab no:
(1) Kev nyab xeeb ntawm cov khoom. Cov khoom ntim khoom noj yuav tsum ua raws li cov qauv kev nyiam huv thiab kev nyab xeeb. Thiab lawv yuav tsum tsis txhob muaj cov tshuaj phem lossis kab mob.
(2) Rov ua dua tshiab. Cov khoom ntim khoom noj yuav tsum tau ua los ntawm cov khoom siv rov ua dua tshiab kom ntau li ntau tau. (xws li biopolymers tauj dua tshiab, cov ntaub ntawv siv dua tshiab, thiab lwm yam.)
(3) Ib puag ncig tus phooj ywg. Cov khoom ntim khoom noj yuav tsum ua raws li cov txheej txheem ib puag ncig. Thiab lawv yuav tsum tsis txhob ua phem rau ib puag ncig thiab tib neeg kev noj qab haus huv.
(4) Kev tswj cov txheej txheem ntau lawm. Cov txheej txheem ntawm cov khoom ntim khoom noj yuav tsum tau tswj nruj me ntsis. Thiab yuav tsum tsis txhob muaj cov pa phem uas ua rau muaj kev puas tsuaj rau ib puag ncig.
2. Kev ua haujlwm ib puag ncig ntawm cov ntawv khob khov nab kuab piv rau lwm cov ntaub ntawv
Piv nrog rau lwm cov khoom ntim khoom noj uas nquag siv, daim ntawv khob khov nab kuab muaj kev ua haujlwm zoo dua qub. Cov feem ntau suav nrog raws li hauv qab no.
(1) Cov ntaub ntawv tuaj yeem siv dua. Ob daim ntawv thiab txheej zaj duab xis tuaj yeem rov ua dua. Thiab lawv yuav tsum muaj kev cuam tshuam me ntsis rau ib puag ncig.
(2) Cov khoom siv tau yooj yim degrade. Ob daim ntawv thiab txheej zaj duab xis tuaj yeem ua kom sai thiab tsis zoo. Qhov ntawd tuaj yeem ua rau nws yooj yim dua los daws cov khib nyiab.
(3) Kev tswj ib puag ncig thaum lub sijhawm tsim khoom. Cov txheej txheem ntau lawm ntawm daim ntawv ice cream khob yog ib puag ncig tus phooj ywg. Piv nrog rau lwm cov ntaub ntawv, nws muaj tsawg dua emissions ntawm cov pa phem.
Hauv qhov sib piv, lwm cov khoom ntim khoom noj uas nquag siv muaj teeb meem loj dua ib puag ncig. (xws li yas, foamed yas.) Cov khoom yas tsim muaj ntau cov pov tseg thiab cov pa phem emissions thaum lub sij hawm tsim khoom. Thiab lawv tsis yooj yim degraded. Txawm hais tias foamed yas yog lub teeb thiab muaj kev txuag hluav taws xob zoo. Nws cov txheej txheem ntau lawm yuav ua rau muaj kuab paug ib puag ncig thiab teeb meem pov tseg.
3. Puas muaj cov pa paug paug thaum lub sij hawm tsim khoom ntawm daim ntawv ice cream khob
Daim ntawv ice cream khob tuaj yeem tsim me me ntawm cov pov tseg thiab emissions thaum lub sijhawm tsim khoom. Tab sis tag nrho lawv yuav tsis ua rau muaj kuab paug loj rau ib puag ncig. Thaum lub sij hawm tsim khoom, cov pa phem tseem ceeb suav nrog:
(1) Cov ntawv pov tseg. Thaum lub sij hawm tsim cov ntawv ice cream khob, ib tug npaum li cas ntawm cov ntawv pov tseg yog generated. Tab sis cov ntawv pov tseg no tuaj yeem siv rov ua dua lossis kho.
(2) Kev siv hluav taws xob. Kev tsim cov ntawv ice cream khob yuav tsum muaj qee lub zog. (xws li hluav taws xob thiab cua sov). Cov no kuj tuaj yeem cuam tshuam tsis zoo rau ib puag ncig.
Qhov ntau thiab qhov cuam tshuam ntawm cov pa phem no tsim los ntawm cov txheej txheem tsim khoom tuaj yeem txiav txim siab los ntawm kev tswj xyuas tsim nyog.
Tswj thiab siv cov kev tiv thaiv ib puag ncig los tswj thiab txo.
