Beneficial Reuse

of

New Construction

Scrap Gypsum Drywall


The Problem

Excessive Volume

1 Pound of Scrap Gypsum Drywall is Generated for Every Square Foot of Floor Area in a New House

A 2,000 Square Foot House = 1 Ton of Waste Gypsum Drywall!

A Year’s Worth of New Construction =

Over 8Billion Pounds of Drywall Scrap Annually in the U.S.A.


Hazardous Decomposition

Under Certain Landfill Conditions Anaerobic Decomposition of Waste Gypsum Drywall Produces Toxic Hydrogen Sulfide Gases

also

Excessively Wet Landfill Conditions may Produce Toxic Hydrogen Sulfates Threatening Groundwater Resources

Environmental Time Bomb

Numerous Landfills Today Now Emit These Toxic Pollutants due to Decades of Gypsum Drywall Disposal


A Brighter Future

  • Halting the Flow of Gypsum Drywall Scrap to Landfills Yields Immediate Results

  • Landfill Space is Preserved

  • Hydrogen Sulfide/Sulfate Production is COMPLETELYEliminated


Waste Stream Diversion

  • Diverting Scrap Gypsum Drywall from Landfill Disposal Produces:

  • Immediate Benefits

  • Makes More Landfill Space Available

  • Defuses Potential Environmental TIME BOMB

  • CreatesBeneficial Gypsum-Based Products


Reclamation is the Answer

Not Recycling

  • Transportation Costs for Scrap Gypsum Drywall Back to Factories is Prohibitive

  • Alternative Reuses

  • Agricultural Gypsum

  • Animal Bedding and Odor Control


  • Moisture Control

  • Pond Clarification

  • Landfill Capping

  • Reclamation of Sodic Soils

  • Gypsum improves soil structure

  • Gypsum prevents crusting of soil and aids seed emergence

  • Gypsum improves low-solute irrigation water


  • Gypsum improves compacted soil

  • Gypsum makes slightly wet soils easier to till

  • Gypsum stops runoff and erosion

  • Gypsum decreases pH of sodic soils

  • Gypsum improves swelling clays

  • Gypsum prevents water logging of soil

  • Gypsum helps make stable soil organic matter

  • Gypsum makes water-soluble polymer soil conditioners more effective


  • Gypsum makes magnesium non-toxic

  • Gypsum corrects subsoil acidity

  • Gypsum improves water-use efficiency

  • Gypsum creates favorable soil electric conductivity

  • Gypsum makes it possible to use low quality irrigation water

  • Gypsum decreases dust erosion

  • Gypsum helps plants absorb plant nutrients


  • Gypsum decreases heavy-metal toxicity

  • Gypsum increases value of organics

  • Gypsum improves fruit quality and prevents some plant diseases

  • Gypsum is a source of sulfur

  • Gypsum helps prepare soil for no-till management

  • Gypsum decreases bulk density of soil

  • Gypsum decreases the toxic effect of sodium chloride salinity


  • Gypsum keeps clay off tuber and root crops

  • Gypsum multiplies the value of other inputs

  • Gypsum can improve pH of rhizosphere

  • Gypsum decreases loss of fertilizer nitrogen to the air

  • Gypsum can be a source of oxygen for plants

  • Gypsum helps earthworms to flourish

  • Gypsum can increase crop yields


Ag Gypsum History

  • Gypsum has been used as a soil amendment for over 200 years

  • Gypsum improves air & water infiltration

  • Gypsum improves rooting in acid subsoils

  • Gypsum supplies calcium and sulphur to plants

  • Gypsum reclaims high sodium soils along highways


Changing Waste Gypsum Drywall into Ag Gypsum

Reduced Waste Gyp Board Particle Size is Critical for Conversion to Agricultural Use

  • Tree Limb Chippers Do Not Work to Chip Up Gypsum Drywall


Tree Limb Chippers Do Not Work to Chip Up Gypsum Drywall


Changing Waste Gypsum Drywall into Ag Gypsum

Reduced Waste Gyp Board Particle Size is Critical for Conversion to Agricultural Use

  • Tree Limb Chippers Do Not Work to Chip Up Gypsum Drywall

  • Hammermills are Useless



Changing Waste Gypsum Drywall into Ag Gypsum

Reduced Waste Gyp Board Particle Size is Critical for Conversion to Agricultural Use

  • Tree Limb Chippers Do Not Work to Chip Up Gypsum Drywall

  • Hammermills are Useless

  • Reduction of Particle Size by Manure Spreaders is notPractical



Reduced Waste Gyp Board Particle Size is Critical for Conversion to Agricultural Use

Why?


Changing Waste Gypsum Drywall into Ag Gypsum Conversion to Agricultural Use

Disintegrating Waste Gypsum Drywall Board Forces Intimate Contact With Oxygen

Thus Eliminating the Possibility of Anaerobic Decomposition and the Production of Hazardous Compounds


Disintegrated Waste Gypsum Drywall Board Forces Intimate Contact With Oxygen

Eliminates the Production of Hazardous Compounds


Is There an Efficient Way to Change Waste Gypsum Drywall into Ag Gypsum?

Yes!

Yes There Is!!!

Bridges the Gap Between into Ag Gypsum?

  • Landfill Disposal Only

  • Extremely Expensive Mega-Machines

  • Gyp Monsters Cost Less than the Average Car

  • Specifically Designed for Scrap Gypsum Drywall

  • Produce Varied Particle Sizes with Ease
