Fopela rijen i gat ol narapela narapela samting we i save kirapim wok bilong risaikel kolta. Dispela atikol i givim wanpela skelim namel long ol rijonal na wanpela global baisa disisen fremwok.
Ol rot bilong divelopmen na ol bikpela samting we i save kirapim wok bilong risaikel kolta long 4-pela bikpela rijen bilong wol i soim bikpela senis. Bikpela samting we i save kirapim Afrika em i hevi bilong mani na sot bilong foren eksens — gutpela bilong risaikel teknoloji i stap long daunim foren eksens ekspendis long ol 'imported bitumen' na 'aggregate'. Bikpela samting bilong Saut-is Esia em ol salens bilong klaimet — hat na bikpela ren i save strongim ol gutpela samting bilong ol 'recycled pavement'. Bikpela samting bilong Yurop em ol 'carbon constraints' na ol teknikel standet - gutpela bilong 'recycling' teknoloji i no stap tasol long sevim kos tasol moa long 'carbon credits' na ol gutpela samting bilong bihainim lo. Bikpela samting bilong Amerika em RAP ekonomiks na FHWA teknikel standet — gutpela bilong risaikel teknoloji i stap long senisim RAP we i no gat bikpela pe i go long gutpela rot. Long kliagut long ol dispela samting i narapela em i bikpela samting long ol manmeri i baim ol samting long wol: veliu proposisen bilong wankain 'rejuvenator' prodak i mas i no wankain long olgeta rijon.
Rot indastri long wol i wok long senis tru long 'kabon emisen em i wanpela hevi bilong envairomen' i go long 'kabon emisen em i wanpela kos bilong bihainim lo'. EU ETS i gat prais bilong kabon we i stap klostu long 60-80 yuro long wan wan tan bilong CO2, na i go antap. Taim Amerika i no gat wanpela yunifaid federal kabon maket, kabon treding sistem bilong California na RGGI (Regional Greenhouse Gas Initiative) bilong Not Is i wok long skruim wok bilong ol. Nesenel kabon maket bilong Saina i stat pinis, wantaim prais bilong kabon i stap olsem 50-80 yuan long wan wan tan bilong CO2. Long ol manmeri i baim ol samting long wol, wanpela bikpela samting i kamap em olsem ol 'carbon constraints' i wok long senis long 'volantia komitmen' i go long 'mandatori standet'. Insait long dispela samting, 30% 'emission reduction' bilong 'warm-mix recycling' i senis long wanpela 'envairomen hailait' i go long wanpela 'komplaiens nesesiti'. Long ol global saplaia, bikpela samting bilong go insait long ol maket we i no gat planti kabon em long skelim na soim olsem ol rot bilong risaikel i save daunim kabon.
COVID-19 sik i soim olsem ol wok bilong salim ol samting bilong rot long wol i no strong tumas. Long 2020, global bitumen saplai sen i bin bungim bikpela hevi, we prais i bin go antap moa long 50% long planti kantri. As bilong ol dispela hevi em bikos ol i save dipen tumas long ol 'centralized supply model' we i dipen long ol 'long-distance' trenspot. Tasol, RAP risaikel i givim wanpela gutpela rot: yusim ol samting bilong ples. RAP em i wanpela samting bilong ples — em i stap pinis long rot netwok bilong ples. Asphalt rejuvenator em i wanpela samting we i save kamap long ples yet — maski ol samting bilong en i kam long ol narapela kantri, ol i ken tanim tanim na putim gen long ples bilong en. Ol i bin skelim gen veliu bilong dispela lokaliset saplai sen long taim bihain long sik i kamap. Long ol manmeri i baim ol samting long wol, wanpela bikpela samting bilong mekim disisen em olsem ol i mas tingim 'supply chain resilience' insait long 'supply evaluation' wantaim kos na pefomens.
I gat bikpela senis long 'technology readiness level' (TRL) bilong 'asphalt recycling' long olgeta 4-pela rijon. Yurop na Amerika i stap long TRL 8-9 — teknoloji i bin kisim validesen long planti bikpela projek, wantaim ol gutpela standet na spesifikasen. Saut-is Esia i stap long TRL 6-7 — ol i bin skelim teknoloji long ol pailot projek, tasol ol standet na spesifikasen i wok long kamap yet. Afrika i stap long TRL 4-5 — teknoloji i bin kisim validesen long ol liklik pailot projek, tasol bikpela diploimen i nidim yet ol teknikel standet na lokal adaptesen. Long ol manmeri i baim ol samting long wol, sapos ol i kliagut long TRL level bilong rijon bilong ol, dispela i helpim ol long makim ol samting ol i ting bai kamap na ol rot bilong menesim ol hevi. Long ol rijen we i no gat planti TRL (olsem Afrika), ol baia i mas putim ol solusen we i no gat planti teknikel banis na i no nidim ol spesel ikwipmen. Long ol rijen we i gat planti TRL (olsem Yurop), ol baia i ken askim long kisim moa teknikel pefomens na moa ful setifikesen pepa.
Taim ol i makim 'asphalt rejuvenator' bilong ol wok bilong wokim rot long wol, ol baia i mas askim ol dispela 7-pela askim. Namba wan, wanem kain disain laip bilong dispela projek? Sapos laip bilong disain i aninit long 5-pela yia, opsen we i no gat bikpela pe bilong en em i gutpela; sapos laip bilong disain i winim 10-pela yia, orait 'life-cycle cost' opsen we i no gat bikpela pe em i gutpela. Namba tu, ol tambu bilong kabon i strong long rijon? Sapos yes, ol i mas skelim 'carbon reduction' bilong 'recycling solution' na putim insait long mani bilong projek. Namba tri, i gat wanpela RAP risos i stap? Kwaliti na saplai stebiliti bilong RAP em i as bilong risaikel fisibiliti. Namba foa, wanem kain kondisen bilong ol ikwipmen bilong ol lokol miksing plent? Sapos ol ikwipmen i wok long go lapun, wok bilong 'warm-mix recycling' long liklik hat inap long daunim hevi bilong ol ikwipmen. Namba faiv, saplaia inap long givim lokal teknikel sapot na miks disain helpim? Long ol rijen we i no gat planti teknikel inap, veliu bilong teknikel sapot i save winim prais bilong prodak. Namba sikis, wanem em i stebiliti bilong saplaia bilong saplaia? Long ol rijon we i gat ol saplai sen we i no strong tumas, ol samting bilong ples na ol samting bilong lojistik em ol bikpela samting bilong tingim. Namba seven, dispela 'rejuvenator' i stret wantaim kain 'bitumen' we ol i save yusim long ples? Ol narapela narapela rijon i save yusim ol narapela narapela kain 'bitumen' (olsem, 'high-polymer modified bitumen' long Yurop, 'basic bitumen' long Afrika), na 'compatibility' em i wanpela samting we i mas kamap pastaim long teknikel 'feasibility'.
Wanpela bikpela tingting bilong global rot indastri em olsem wok bilong risaikel kolta i no gat 'global optimal' solusen, em i gat 'regional optimal' solusen tasol. Gutpela rot bilong stretim hevi bilong Afrika em i wanpela 'rejuvenator' we i no gat planti hevi long sait bilong teknikel, liklik 'packaging', na ol i ken senisim pe bilong en. Gutpela rot bilong Saut-is Esia em i wanpela 'rejuvenator' we i gat bikpela 'thermal stability', strongpela wara i no inap bagarapim, na i ken wok wantaim 'modified bitumen'. Gutpela rot bilong Yurop em i wanpela 'rejuvenator' we i inapim ol EN standet, inap long skelim 'carbon reduction', na i gat olgeta setifikesen pepa. Gutpela rot bilong US em i wanpela 'rejuvenator' we i bihainim ol stia tok bilong FHWA, i gat strongpela pefomens data, na i ken wok wantaim ol lokal saplaia. Long ol global saplaia, ki bilong kamap gut em i no 'wanpela prodak bilong global maket' tasol 'wanpela as teknoloji, ol narapela narapela veliu proposisen' — stretim prodak posisen na maketing mesej bihainim ol as draiva bilong ol narapela narapela rijon. Ol i wokim 'rejuvenator' bilong FangService wantaim ol dispela rijonal difrens long tingting: ol bikpela teknikel indiketa (viskositi 280 mPa·s, 'flash point' 231°C, gutpela wok bihain long RTFOT) i gat gutpela kompetisen long olgeta hap bilong wol, na ol spesifikesen bilong paket (25 kg o 1,000 kg dram) na (DFO / FOT) i gat ol tok we i no stret ol i ken stretim gut bihainim ol nid bilong rijonal.
