NTEP Certification

ExBio

The LFC biodigester is the only food waste digester to achieve NTEP certification. Without NTEP certification for your biodigester, reporting the weight of food waste diverted from a landfill in your corporate report is akin to fabricating the figures.
NFC Card Reader

The NFC card reader on LFC biodigesters allows you to identify the source or type of waste food placed into the food waste digester and automatically create reports and charts. Quantify and track the amount of waste that a specific event or multiple events generates. To our knowledge, this feature does not exist on any other biodigester.
