- Marketing of energy and digestate
It Makes All The Difference
We build Second-Generation anaerobic digesters. They produce up to 35% more energy for every kilogram of waste received, and that’s a huge advantage. They’re also inherently much more stable and easier to manage.
What’s a Second-Generation Digester? It’s simple: our digestion process is separated into two phases, each of which must be completed in separate vessels in the plant.
Raw wastes are broken down into very simple compounds in the first phase. This initial step is required to make waste by-products available for methane production in the second phase.
Here’s the key—each of the two steps requires a significantly-different temperature and pH environment inside the vessel, to produce optimal results.
First-generation digesters, (designed to process very consistent and simple materials like bio-energy crops) force both phases into a single vessel, leading to greater instability and lower rates of energy production when dealing with complex waste streams.
Second-Generation digesters are the best choice for mixed commercial organic wastes, and for municipal ‘green bin’ collection programs, simply because these waste streams are so variable.
