Omega Protein Corporation has developed processes to conserve about 18 million gallons of water annually by reclaiming water through the processing of fish, rather than removing that water from the ground, the company says. The water is treated and then used in the plant to wash down equipment and used to seal the vacuum pump in the company’s evaporator.
As part of its water-conservation efforts, the company recently installed a Dupps evaporator (pictured) at its Reedville, Va. facility, which it says is the first of its kind in North America. Omega Protein says this evaporator alone saves about 2.1 million gallons of groundwater annually.
The nutritional product company that produces omega-3 fish oil and specialty protein products says water reclamation and reuse is just one of environmental initiatives undertaken at its Reedville, Va. facility in recent years. Omega Protein puts the price tag on these upgrades at well over $20 million.
Some of these projects include:
- Switching to renewable diesel oil (waste animal fats) in the company’s boilers in its processing facility. This allows the company to use a cleaner burning, carbon neutral product.
- Installing art airless dryers that allow the company to incinerate non-condensable gases. Omega Protein says it is the only location in North America with this technology.
- Equipping the company’s two upgraded fishing vessels with two new Tier 2 engines and five new auxiliary Tier 2 engines that burn less fuel and therefore reduce emissions.
Last week multifamily housing real estate firm Peabody Properties said it will use web-based utility analytics company WegoWise’s building management platform to target more than 300 water retrofits across its high-rise building stock, where older buildings contain less efficient infrastructure and appliances.
Under a pilot program, the company will install new toilets, aerators and shower heads at five properties, upgrades that will save an estimated $180,00 in gas and water bills annually. Peabody expects the return on investment to be two years or less.
Peabody Properties has also reduced energy use by 5 million kWh, saving the real estate firm $1 million in electricity costs annually through a building retrofit program led WegoWise.
