US 6,846,131 B2 · Methods and facilities for producing revenue from gypsum-based refuse sites

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. Advantageously, methods of the invention comprehend also the storage and processing of non-gypsum waste materials within a containment facility according to the invention, and the sale or further use of products derived from that processing.

Dependent claims

A method for producing revenue from one or more facilities formed from gypsum refuse, said method comprising the steps of:

A. providing at least one facility suitable for the containment of non-gypsum waste materials, said facility comprising a container having one or more concavities, said container being formed substantially from said gypsum refuse consisting of one or more existing gypsum stacks or a gypsum waste stream as it is forming or enlarging a gypsum stack, and
B. renting, leasing or otherwise deriving revenue from said at least one facility suitable for the containment of said non-gypsum waste materials.

A method for producing revenue from gypsum-based refuse, comprising the steps of:

A. providing a site having gypsum-based refuse thereon or therein, said gypsum refuse consisting of one or more existing gypsum stacks or a gypsum waste stream as it is forming or enlarging a gypsum stack, and
B. providing a facility comprising at least one container suitable for storing or processing wastes, said container having one or more concavities, said at least one container being formed substantially from said gypsum-based refuse and essentially free of other components except for aqueous-based fluids, cementitious additives, and structural reinforcements, and
C. renting, leasing or otherwise deriving revenue from said at least one facility suitable for the containment of said non-gypsum waste materials.

A method for producing revenue from one or more containers formed from gypsum-based refuse, wherein said gypsum-based refuse consists of one or more existing gypsum stacks or a gypsum waste stream as it is forming or enlarging a gypsum stack, said method comprising the steps of:

A. providing a site suitable for having said gypsum-based refuse thereon or therein,
B. placing said gypsum-based refuse in or on said site,
C. forming said gypsum-based refuse into at least one container suitable for storing or processing non-gypsum based waste materials, wherein said gypsum-based refuse is free of other components except for aqueous-based fluids, cementitious additives, and structural reinforcements, and
D. renting, leasing or otherwise deriving revenue from said at least one container suitable for the containment of said non-gypsum waste materials.
