The Customer:
Crescent Duck Farm, located in Aquebogue, Long Island, N.Y., produces premium fresh and frozen ducks and duck products. Family-owned since 1908, Crescent Duck’s breeding and processing efforts have ensured that its products meet the standards of even the most discerning white tablecloth restaurants and Asian food trades.

The Customer’s Needs:
Crescent Duck required a cover to collect biogas from its anaerobic digester, which treats waste and barn manure from its facility. Because of the cool New York climate, the digester and cover needed insulation to maintain the proper temperature range for anaerobic digestion year round.

The original digester cover was problematic and constantly needed repairs. Plans to clean out the digester and reinstall mixing equipment presented the perfect opportunity for Crescent Duck to replace the failing cover with a more reliable one.

The Solution:
Crescent Duck, in coordination with its engineering consultants at Applied Technologies, Inc., contacted Geomembrane Technologies Inc. for advice on replacing the damaged cover. As part of its research efforts, Crescent Duck visited a plant that had installed a GTI insulated gas collection cover and saw the quality and durability of the product first-hand. The information gathered at the site visit, combined with trust in GTI’s knowledgeable staff and a fair price, showed Crescent Duck the value in choosing GTI for its own replacement cover.

The new cover design consists of Seaman Corporation’s XR-5 for biogas collection with 2 in (5 cm) of flexible polyfoam insulation. The entire replacement took only one week to complete.

The Results:
Crescent Duck’s new GTI cover system is more durable than the original and will last for many years. The new cover is well insulated and will provide Crescent Duck with continuous, efficient biogas recovery and rainwater drainage, thus lowering operation and maintenance costs. Workers can now safely walk on the cover to take waste samples and access equipment.
