Berkshire continues its effort to reduce the environmental impact of cleanroom wipers with the introduction of EcoClean^® 100% cotton non-woven cleanroom wipers. In March 2009, EcoClean^® 35 and EcoClean^® 60 were introduced to the market. Both wipers are 100% biodegradable and made from renewable/sustainable cotton. These attributes combined with higher absorbency per unit weigh than leading polyester/cellulose blended wipers = fewer wipers used with less depletion of natural resources, reduced lbs. to waste disposal, and reduced impact when disposed of in landfills.
