Biogas

High Solids Anaerobic Digestion (HSAD) of organic material produces renewable energy in the form of biogas. In addition to generating renewable energy, HSAD projects divert material from landfills, produce heat that is used for cold storage, and produce a compostable digestate for use on fields and gardens. The HSAD process is an elegant solution to address issues with agricultural waste streams, recycling organic material otherwise destined for the landfill, and producing process steam and baseload renewable energy.

PLP is developing a HSAD project on the Westside of Kauai that will integrate the farming communities needs and benefit the island by producing baseload renewable energy. 

Major Benefits of a HSAD project on Kauai include:

• Baseload renewable energy
• Reduction in the amount of material destined for the landfill
• Waste stream management for farm animal production facilities (hog and cattle)
• Waste stream management for Kauai County Waste Water Sludge (In accordance with health regulations)
• Utilization of thermal output as a source of low cost refrigeration for cold storage
• Compost for farmers and gardeners
• Potential as a “firming agent” for other nearby intermittent generating facilities, including the proposed Hydro and Solar.
