Caagtu waa astaanta bulshada warshadaha horumarsan, wax-soo-saarka ballaaran iyo isticmaalka tirada badan. Laakin sidoo kale waa maaddooyin keena dhibaatooyin bulsheed oo ka dhasha dib-u-isticmaalka badeecooyinka cusub ee caagagga ah ama ka faa'iidaysigeeda sida kheyraadka-tillaabooyinka loo qaaday si looga hortago xaalufka kheyraadka, si loo ilaaliyo deegaanka caalamiga ah iyo in lagu daweeyo qashinka la tuuray.
Dib-u-warshadaynta caagagga qashinka waxay inta badan u qaybsantaa dib-u-soo-noolayntooda sida alaabta ceeriin iyo ka faa'iidaysigooda shidaal ahaan. Kan hore waxa uu u baahan yahay daawaynta ku dhawaad 100% daahirnimo; kan dambe, ka saarida PVC, oo ah arrin ka mid ah jiilka dioxin iyo chlorine gaseous, waa arrin. Marka la soo koobo, kor u qaadista dib-u-warshadaynta waxay u baahan tahay horumarinta isticmaalka farsamada ee farsamada si loo kala saaro culeyska isku dhafan ee noocyada kala duwan ee caagadaha.
Habka shaqada ee agabyada kala duwan waxaa si elektaroonik ah u dallacaya kicinta kicinta weelka dhexdiisa. Isticmaalka korantada durbaanka wareega, alaabta si togan iyo si xun u dallaca ayaa loo diraa goobta korantada ee ay sameysteen electrodes counter-ka. Tani waxay kor u qaadaysaa soo-gelinta caagga si togan loo dallacay dhinaca korantada taban iyo balaastigga si xun u dallacaya dhinaca elektrodegga togan. Natiijadu waa kala-soocidda nadiifka sare ee caagadaha kala duwan ee lagu soo oogay. Mid ka mid ah kiisaska kala soocida qaybaha PVC ee la jajabiyey (xajmiga 5mm) iyo polyetylen (PE) (2mm) waxay muujineysaa nadiifnimada PVC ee 99.6% (oo leh heerka soo kabashada ee 85%) iyo nadiifnimada PE ee 99.7% (oo leh 58% heerka soo kabashada).
