Degradation of Superabsorbent Polymers

Are superabsorbent polymers (SAPs) biodegradable? Will SAPs release liquids in a landfill? These questions are asked by many professionals in the environmental waste management industry when considering SAPs for a project. SAPs are used globally to solidify liquid waste streams safely and efficiently prior to final disposal or reuse. However as with any waste treatment reagent, it is important for environmental practitioners to understand how SAPs behave once they are disposed in a landfill or left on-site as a component of fill material.

Superabsorbents for Vacuum Truck Contractors:  The safe, fast, and low cost choice for managing liquid waste

The rapid increase in horizontal directional drilling (HDD) activities throughout North America has resulted in a higher demand for vacuum truck services to manage liquid waste streams. And while drilling contractors and pipeline maintenance crews often rely on the convenience and efficiency of hiring a vacuum truck to get liquid waste out of their way, the next step in the process, liquid waste solidification, is often not as efficient or cost effective as it could be. Low-end commodity absorbents, like those that are widely used in the waste treatment industry, present several challenges to environmental contractors. Fortunately, superabsorbent polymers (SAPs) offer a safe, efficient, and cost-effective solution to liquid waste solidification.

Using Superabsorbent Polymers To Reduce Dredged Sediment Management Costs, Time, and Environmental Impacts

 

Dredging of saturated sediments from waterways, lakes, and storm water ponds generates massive quantities of waste material that require costly and time-consuming management practices, such as dewatering, solidification, transportation, and off-site disposal.  If solidification of saturated sediments, followed by transportation and disposal, are parts of the work plan at your site, superabsorbent polymers (SAPs) can help to reduce your budget as well as time on-site, and they can minimize environmental risks.
