Abstract: The invention pertains to means and methods for enabling the further use of previously negative assets, and particularly from those facilities formed from gypsum waste, such as that suitable for forming gypsum stacks. Waste containment or landfill facilities are formed from the conversion of gypsum refuse waste materials derived from gypsum mining and processing, and particularly from such facilities as they are formed in place from such gypsum-based refuse. Such facilities can be utilized, rented or leased as waste containment facilities for the short-term, long-term or permanent storage of non-gypsum waste materials such as solid waste, community refuse materials, biomass, industrial waste, phosphate waste, and for composting or otherwise processing materials such as biomass.

Abstract: The invention pertains to business methods for enabling the creation of positive revenue streams from previously negative assets, and particularly from those facilities formed from gypsum waste, such as gypsum stacks. Waste containment or landfill facilities are formed from the conversion of gypsum refuse waste materials derived from gypsum mining and processing, such as from existing gypsum stacks, or from facilities formed in place from gypsum-based refuse. Such facilities are utilized, rented or leased as waste containment facilities for the short-term, long-term or permanent storage of non-gypsum waste materials such as solid waste, community refuse materials, biomass, industrial waste, phosphate waste, and for composting or otherwise processing materials such as biomass.

Abstract: Numerous embodiments of a synthetic drainable base course (“SDBC”), and paved structures that may advantageously include an SDBC, are provided. As a key advantage of SDBC's according to the invention, they are of sufficient capacities and structural strength to be used within layered paved structures such as highways, airport runways and parking lots, to provide drainage superior to that afforded by conventional means and methods involving the use of open graded base courses that are typically formed of natural soils and aggregate and are extremely expensive to install. The invention includes means and methods that use conventional heavy equipment for installing an SDBC during the construction of a roadway or other paved surface.
