Composition of Alternative Daily Cover Materials with a Perspective of Use of Latvian Local Resources / Alternatīvo ikdienas pārklājumu materiālu sastāva pētījumi ar perspektīvu Latvijas vietējo zemes dzī?u resursu izmanto?anai

摘要

This paper focuses on alternative daily cover materials intended for use in solid municipal waste landfills. Currently available and proposed cover materials are described by type. The functional contribution of cover components was considered. Special attention was given to alternative daily cover materials in form of sprayable slurries or emulsions. Using the obtained data, conclusions were drawn concerning the most promising components and compositions of sprayable alternative daily covers. Particularly promising components of sprayable daily covers for the use in local environment (Latvia) are clays, which are found in abundance in local mineral deposits.
