ENVIRONMENTAL CONTAMINATION INHIBITION

摘要

A system for reducing environmental contamination from structure demolition can include a fluid first aqueous composition having an alginic acid or alginate dissolved in water, and a fluid second aqueous composition having a calcium salt dissolved in water. The system can be used in a method for reducing environmental contamination from structure demolition. The method can be conducted by: applying the first aqueous composition to a structure to be demolished; applying the second aqueous composition to the first composition on the structure such that the alginic acid or alginate undergoes gelation into a gel; and demolishing the structure such that the gel captures particles and inhibits environmental contamination from the particles.
