In 1957, Honeywell, along with Ratheon, introduced one of the first computers in the U.S., the Datamatic 1000. , which installed the plant in Sigma's Lyndhurst industrial park.
Honeywell Home and Building Control in Morristown, N.J., runs and maintains the co-generating plant for Sigma under a seven-year lease and a management contract. Honeywell's contract includes an on-site engineer and 24-hr surveillance of the power plant by Honeywell.
The package represents an investment of $6.5 million for Sigma, but after the lease expires, Sigma will own the equipment. Sigma ultimately will save a lot on energy because Honeywell guarantees at least $1.2 million/yr in cost savings after the lease is up. That includes Honeywell's $400,000/yr contract to continue running the plant.
Sigma had also expected to achieve modestly positive cash flow during the seven-year lease. The "co-gen" plant was supposed to save about $100,000/year in energy cost almost immediately. But that was before natural gas prices soared.
When Sigma struck the deal with Honeywell, natural gas cost about $2.80 a decatherm. But no sooner did Sigma fire up its co-gen plant last November, than natural-gas prices soared. In December, January, and February, gas hit all-time highs of over $10 a decatherm. That meant that in the short term, generating its own power wouldn't save Sigma much, if anything, over buying electricity on the outside.

[Middle English daunten, from Old French danter, from Latin . And it isn't waiting around for the seven-year lease to end or for gas prices to drop. Sigma is already exploring a deal proposed by its next-door neighbor, the Kingsland Landfill, which could supply enough methane gas from the landfill to fire Sigma's co-gen plant. The landfill currently flares off almost exactly the same amount of methane as Sigma uses in natural gas, says Bob Silk, Honeywell's on-site technical-resource manager. The co-gen engines, which are built by JenbacherAGinAustria, can be readily converted to run methane and frequently are methane-fired in Europe, Silk says.
Sigma Plastics operates 19 plants in the U.S. and three in Canada. Its Lyndhurst campus was chosen for the co-gen experiment not because it is such a big energy user, but because its energy is expensive. Lyndhurst houses Sigma headquarters and three film and bag-making plants processing 90 million lb/yr of stretch film, T-shirt bags, and merchandise and produce bags. It consumes about $250,000 a month of electricity. Sigma's stretch-film plant in Kentucky Kentucky, state, United States
Kentucky (kəntŭk`ē, kĭn–), one of the so-called border states of the S central United States. It is bordered by West Virginia and Virginia (E); Tennessee (S); the Mississippi R. processes a lot more resin--120 million lb/yr. But whereas power in Lyndhurst costs 8-9[cent]/kwh, power in Kentucky costs only 4-5[cent]/kwh.

It consists of two principal parts: the furnace, which provides heat, usually by burning a fuel, and the boiler proper, a device in which the heat changes water into steam. produces hot water at 210 F, which provides heat absorption for the chiller that supplies cooling water to all three buildings. That chiller replaces three electrically powered chillers, which were expensive to run. "Now chilling the water doesn't use electricity. It's entirely a byproduct by·prod·uct or by-prod·uct

Noun 1. of heat generated by the co-gen plant," explains Mark Teo, Sigma's executive v.p.
The co-gen plant should provide more reliable power, too. It generally runs around the clock, except for a week in July and a week in December when Sigma closes. The co-gen equipment at Sigma consists of two 1400-kwh gas-fired engines capable of generating a total of 23,000 Mwh/yr. They will supply about 70% of Sigma's power needs in Lyndhurst.
Sigma is probably already one of the first plastic processors to generate its own power. If the landfill pipeline goes through, Sigma would almost certainly be the first to tap methane from a landfill.
