From fluctuating PCR input to stable, high-performance compounds

The increas­ing use of post-con­sumer recy­cled mate­ri­als intro­duces a fun­da­men­tal chal­lenge: vari­abil­i­ty. Unlike vir­gin poly­mers, PCR streams vary in com­po­si­tion, con­t­a­m­i­na­tion, and mechan­i­cal behav­ior. This vari­abil­i­ty cre­ates insta­bil­i­ty in pro­duc­tion and makes it dif­fi­cult to achieve con­sis­tent prod­uct qual­i­ty. Tra­di­tion­al recy­cling process­es focus on regran­u­la­tion. How­ev­er, this does not address the core issue: mate­r­i­al incon­sis­ten­cy. […]

Why waterless film recycling is changing the economics of post-consumer plastics

Film recy­cling is one of the most chal­leng­ing seg­ments in plas­tics pro­cess­ing. The com­bi­na­tion of con­t­a­m­i­na­tion, mois­ture, and low-den­si­­ty mate­r­i­al cre­ates insta­bil­i­ty through­out the entire process chain. Tra­di­tion­al wash­ing sys­tems attempt to solve this prob­lem but intro­duce new chal­lenges: – high water con­sump­tion – ener­­gy-inten­­sive dry­ing – com­plex plant lay­outs – ris­ing oper­at­ing costs As […]

How to achieve stable food-grade rPET despite fluctuating input streams

The biggest chal­lenge in food-grade PET recy­cling is no longer col­lec­tion or sort­ing. It is process sta­bil­i­ty. Recy­clers today are deal­ing with increas­ing­ly vari­able input streams. Bot­tle flakes, tray mate­r­i­al, and mixed PET sources all behave dif­fer­ent­ly dur­ing pro­cess­ing. These vari­a­tions direct­ly impact intrin­sic vis­cos­i­ty (IV), acetalde­hyde (AA), and final prod­uct qual­i­ty. With­out pre­cise process […]
