AD Feedstock Solutions

Focusing on feedstock preservation for the AD industry

Since 1982 our parent company, Kelvin Cave Ltd, has pioneered and developed products that have been leading the way in innovative forage preservation. This led us to develop AD Feedstock Solutions as a dedicated arm of the business, focused on those in the AD industry using ensiled energy crops as a feedstock.

All our products are independently researched – they have to add value to your business to be of value to ours.

Even with the most advanced AD plant and the best engineers, without the right feedstock management system your biogas plant will never reach its full potential. From field to feed-out, an average of 25% of the silage dry matter* is lost, primarily as carbon dioxide and water, due to inefficiencies in the ensiling process. This results in lower biogas yields.

Forage preservation is key to helping improve biogas production. Done poorly it not only loses dry matter, creating a reduction in biogas yield, it may also cause complications in the digester.

At AD Feedstock Solutions we can help you streamline your forage preservation and clamp management process by getting to grips with the science behind it – leading to a more profitable biogas future.
