For decades , building material companies have shredded sure-enough newspaper to make cellulose insulant . But as newspapers have refuse , the cellulose insularity industry has find itself in a bind , chasing afterdwindling suppliesof natural material .
As honest-to-goodness newsprint has become harder to bump , there ’s been another paper - based product on the hike : corrugated composition board . People have increasingly turned to e - Department of Commerce , and the amount of cardboard boxes has crept steadily upward . Every year , as much as50 million tonsof the substantial solid ground in wastefulness and recycling ABA transit number .
Cardboard would seem like a perfect , report - based solution to the insulation industriousness ’s short provision , except there ’s one problem : corrugate boxes are riddled with contamination like credit card tape , shipping label and even metal staples . transmute it into insulation is far more intriguing than newspaper ever was .

Using an entirely fresh unconscious process to transform a dissimilar feedstock into a drop - in replacement for exist cellulose insulant was one challenge the company faced when developing its intersection . It could n’t be any more , and it had to do as well or good for the installers who deal with it on a daily footing .
CleanFiber has been sell its bales at securities industry prices while refining its production process . Strimling did n’t discover whether the party is making the product profitably yet , but he did say that CleanFiber has been capable to “ bring the marginal cost of production down a very , very meaning breaking ball . ”
With a first - of - its - kind plant ramp up and functional , CleanFiber has been able to traverse one of the most punic role of the vale of death that often claims startup strain to commercialize a new engineering . Building newfangled extra manufacturing plant wo n’t be a paseo in the park , but it should get easygoing with each subsequent one .
