SYSTEM K4 is an innovative, highly effective, environmentally friendly, and absolutely safe cleaning procedure for commercial textile care, for which we have applied for patents worldwide. SOLVON K 4 is a solvent that is neither hazardous nor hazardous and has cleaning power equal to or partially better than that of conventional cleaning products.

Clearly well designed – SYSTEM K4 for a sustainable future:
SOLVONK4 Dry Cleaning Solvent is part of the SYSTEM K4 process and is now a USDA-certified bio-based and bio-preferred product. Bio-based products are derived from plants and other renewable agricultural, marine, and forestry materials and provide an alternative to conventional petroleum-derived products. SOLVONK4 is 88% bio-based.

A USDA-certified biobased product label indicates the biobased content of the product. source:

These are some of the products that come from renewable resources such as plant, animal, marine, or forestry feedstock. Utilizing renewable bio-based materials replaces the need for non-renewable petroleum-based chemicals.

Ground-breaking bio-based dry cleaning solvent to be produced by Green Biologics and Kreussler Chemicals
A new bio-based alternative solution is now available for dry cleaners. Working with Green Biologics and their facility in Minnesota, Kreussler Inc. is now making dry cleaning solvent from corn grown by about 500 family-owned farms in the heartland of America. Bio-derived and sustainable are words never before applied to the dry-cleaning industry until now. SOLVONK4 offers one single ultrapure solvent that cleans better than Perc without any environmental or health-related concerns.

Bio-based products that replace petroleum have played an increasingly important role in reducing greenhouse gas emissions that exacerbate global climate change.

Bio-based products are inexpensive, readily available, and perform as well or better than conventional products.
