After a Regional Account Manager meets with you to assess your needs, we will provide you with a clean, durable storage container to store used cooking oil, and arrange a collection schedule for you. After each collection, we will record the amount of useable oil, which is usually the majority of the total volume collected. Any rebates will be issued based on that amount depending on your volume.

Frequencies are set based on your historical used cooking oil production and the size of your container. We understand that used cooking oil production can increase based on a variety of factors. If you find your container is filling up more frequently than usual, let us know and we’ll adjust the schedule.

Cleaning frequency will vary depending on the size of your trap and the amount of grease used in your kitchen. Most cities require traps be cleaned frequently enough to maintain less than a specified level of FOG (fats, oils and greases) accumulation. This usually results in cleaning at least once per quarter, and sometimes more frequently. Our Regional Account Manager can help you determine an appropriate cleaning frequency.

99% of the grease trap material we pump is taken to anaerobic digesters, where it is turned into clean energy for heating and power. The remainder is processed at our licensed facilities and treated according to local environmental regulations. No grease trap material is ever put down the drain.

Renewable diesel fuel has several advantages over fossil diesel. Compared to fossil diesel, renewable
diesel can reduce greenhouse gas emissions by up to 75% gas emissions (CO2 equivalent) over its life cycle.

Renewable diesel, or HVO (Hydrotreated Vegetable Oil), is sometimes confused with biodiesel or FAME (Fatty Acid Methyl Ester). The main differences between the two are found in their chemical compositions, performances in cold weather and storage qualities. Biodiesel contains oxygen, making it different from both fossil diesel and renewable diesel and renewable diesel and therefore it cannot act as a 100% substitute. Nearly all OEMs limit biodiesel content to 20% with some only allowing 5%
