The “GEM” at the Plymouth (MA) County Correctional Facility

GEM Overview The GEM is a Landfill Diverter

– Converts useless waste into valuable clean energy Handles mixed waste streams

– Paper, plastic, wood, food, agricultural waste

– Processes up to 3 tons/day Diverts unrecyclable waste from landfill Complements existing recycling programs Occupies a compact footprint (45’ x 9.5’ x 8’)

– Plus Front End/Back End

GEM Benefits Helps achieve sustainability goals Processes unrecyclable waste on-site

where it is generated Eliminates landfill use by 95%

– 5% ash may be placed in landfills or re-purposed

Saves money– Eliminates 95% of waste hauling fees– Lowers energy costs3

What’s Included GEM (45’ ISO container)

– Solid waste pre-processor (shredder, drier, pellet mill, pellet hopper)– Gasifier (Downdraft Gasification)– Non-ferrous and ferrous metal separation– Safety features (TUV certification)– Fire suppression

Automatic ash removal Standard front loader Back-end for energy generation (generator or boiler) & switch gear for

generator Regular design services & permitting assistance Installation and commissioning 90-day labor warranty (next day, 8 X 5) 1 yr parts warranty Remote monitoring service4

Configuration Options- Front End

Conveyor feeding– Multiple capacities available– Restricted card access– Foot pedal operation

Top loading gravity feed Options

– Compactor

6

Configuration Options– Back End CHP

– Power Hybrid fuel genset uses synthetic gas

blended with diesel– Heat

Engine and exhaust heat are recovered for use by facility

Heat only– Boiler runs on synthetic gas– Provides hot air, hot water, or steam– Heat used by facility

7

Remote Monitoring & Controls Over 100 sensors installed throughout the GEM measure a

wide array of parameters Wealth of data provides analysis capabilities

– Anticipate potential maintenance requirements– Evaluate cost savings– Determine environmental benefits

MSW Power engineer remotely monitors details of GEM operation via wireless network interface

Customer has access to a summary screen of operational data

Many data points compiled to generate a real-time kiosk screen.

Thermal decomposition process

Converts solid matter into gaseous form

Resultant gas is flammable GEM methodology –

Downdraft Gasification– Uses high heat in oxygen-

starved process to convert solids into gaseous fuel or “syngas”

– Vacuum pulls gas thru bottom of gasifier with no emissions

– Small-scale efficiency– Low-tar gas producing

system

Gas Data & Noise Level Gas Composition (% of Volume)

– Nitrogen 44%– CO 22%– Hydrogen 18%– Methane 3%– Water 8%– CO2 5%

Gas Energy Content - 160 to 200 BTU/cu ft Noise Levels

– SWP = 65dB at (Pellet Mill Doors)– Gasifier = 66dB (at GEM Container Corner)– SWP + Gasifier + Boiler = 68dB (next to GEM Container)– SWP + Gasifier + Generator = 75dB (23 feet from GEM)
