Mechanical Concrete® was discovered while seeking a civil engineering reuse for waste tires. Each year the USA generates over 300 million waste automotive tires . That’s one tire per person per year. And each year an estimated 650,000 tons of inert tire dust from tire wear enters the environment. According to the US EPA, recyclers grind 80% of the waste tires into shreds. About half these recycled tires are burned as tire-derived-fuel, TDF , which has 25% more BTU’s per ton than coal. Mechanical Concrete® is the first, viable, economical reuse for large quantities of waste tires.
The US EPA hierarchy of solid waste management and environmental sustainability, ranks reduction and reuse of materials as the highest activities ahead of recycle, waste to energy and disposal. Because Mechanical Concrete® makes use of the worn tire’s unique, three-dimensional structural properties, it both reuses and reduces materials and makes ‘going green’ pay a dividend instead of being a cost.
Mechanical Concrete® uses standard, waste automotive tires with both sidewalls removed as the Mechanical Cement® cylinders. These tire-derived-cylinders, TDC, retain their structural tensile strength and function as the low cost, rugged, thin-walled, tensile cylinder for the Mechanical Concrete® cell. Reusing the tire tread structure completely eliminates the costly, high energy, greenhouse gas producing portland cement used in making regular concrete. It also eliminates the need for compaction on roadway and site bases
Mechanical Concrete® is approved on a project basis by the West Virginia Division of Highways Materials Division. The reuse of tire derived materials in civil engineering applications is approved by all state and federal environmental agencies.
