Grease Trap Waste Disposal
Ensuring the Success of Municipal FOG Programs
Municipal FOG programs have become vulnerable due to their dependency on grease haulers to service grease traps at food service establishments. More specifically, if grease hauling services are challenged with options on where to dispose the trap grease they extract from grease traps, municipal FOG programs become at risk of failing.
The source of the problem is the availability of nearby FOG receiving facilities – or rather the lack of availability. Municipal wastewater treatment plants commonly report they are operating at capacity in their ability to process trap grease trucked in by grease haulers. If wastewater treatment plants cannot accept more grease trap waste than they currently do, grease haulers are forced to drive considerable distances far away from their service routes to dispose of the waste they are hauling.
The Compliance Challenges of Municipal FOG Programs
Grease haulers have high operating costs, and due to rising costs associated with grease trap waste disposal, they are passing on these costs to their customers – food service establishments. These escalating costs are placing additional strain on municipal FOG programs because restaurants, for example, feel these programs overly burden them. When this sentiment rises, compliance oftentimes falters despite municipalities’ best efforts to enforce their FOG programs, which are meant to keep FOG out of their sewer systems.
Soaring Dumping Fees: Evidence That There’s a Problem
Dumping fees, also known as tipping fees, have been on the rise. The reason is simple: there is more demand for dumping capacity at FOG receiving facilities than there is availability. This not only means grease haulers have to pay more to dispose of the trap grease they collect from food service establishments, but they also have to incur additional fuel costs to drive long distances away from their collection routes to find FOG receiving facilities that can accept their grease trap waste.
Lack of Access to Local FOG Receiving Facilities Has Hidden Costs
When grease haulers have to drive long distances to dump their grease trap waste, they are essentially taking themselves out of operation. Time is money and there is no money to be made when they are not servicing grease traps. These additional miles also represent a cost in the form of wear-and-tear on their grease-hauling trucks. And lastly, there is an environmental cost associated with the carbon emissions from such driving.
The Argument for New FOG Receiving Facilities is Not Complex
It’s not difficult to understand the need for new FOG receiving facilities to support the success of municipal FOG programs. However, municipal wastewater treatment plants have been averse to the idea because of its impact on existing infrastructure. This has been a completely reasonable perspective that has thwarted prospective projects to build new FOG receiving facilities.
The Solution to Process Trucked-in Trap Grease
What if the impact of grease trap waste disposal on wastewater treatment infrastructure was negligible? Would municipal plant operators reconsider expanding existing FOG receiving stations or building new ones? The answer is likely, YES.
By implementing REA’s Total FOG Solutions® platform, approximately 95 percent of trucked-in trap grease gets converted to low carbon-emissions biodiesel without ever touching wastewater treatment infrastructure. The other five percent is food waste “batter” that is best disposed of through anaerobic digestion. Even if a digester is not being operated, the fact that 95 percent of the grease trap waste is diverted to produce a renewable biofuel presents a solution wastewater treatment plant operators cannot ignore if they are truly interested in bolstering their municipal FOG programs.
FAQs
What is grease trap waste disposal?
Grease trap waste disposal is a process that starts when trap grease is extracted from grease traps at food service establishments by grease haulers. This trap grease is then trucked to FOG (grease, oils, fats) receiving facilities to be disposed of. FOG receiving facilities are commonly located at municipal wastewater treatment plants because over 95 percent of the grease trap waste is water. FOG receiving stations can also be located on private property belonging to environmental services companies that operate dewatering systems. Once dewatered, grease trap waste can be landfilled, incinerated, or fed to anaerobic digesters for biosolids volume reduction or to produce biogas.
How does a grease trap work?
A grease trap is a plumbing device designed to intercept FOG waste before it enters the wastewater system. It works by slowing down the flow of water, allowing fats, oils, and grease to cool and separate from the water. The grease floats to the top, solids settle at the bottom, and cleaner water flows out to the sewer system. Regular maintenance and cleaning are required to ensure the grease trap functions effectively and prevents blockages.
Why is regular grease trap cleaning important?
Regular grease trap cleaning prevents blockages, foul odors, and potential fines due to health and environmental violations. It ensures proper drainage and helps maintain compliance with municipal FOG programs and ordinances.
Can grease trap waste be recycled?
Yes, grease trap waste can be recycled. It is often processed into biodiesel, compost, or used in industrial applications after proper treatment.
How can I schedule a grease trap cleaning service?
You can schedule a grease trap cleaning service by contacting an expert cleaning company. Many service providers offer online booking or phone appointments for regular maintenance.
Who is responsible for grease trap maintenance?
The business owner or property manager is typically responsible for grease trap maintenance. However, some municipalities require regular servicing by certified professionals to comply with municipal FOG program regulations.
How often to clean a residential grease trap?
A residential grease trap should be cleaned every three to six months, depending on usage. If you cook frequently with fats, oils or grease, more frequent cleaning may be necessary.
What is the optimal cleaning interval for grease traps?
The recommended cleaning interval for grease traps varies by usage and size but typically ranges from every one to three months for commercial kitchens and every three to six months for residential homes.
Can I schedule regular maintenance for my grease trap?
Yes, many professional grease trap cleaning services offer scheduled maintenance plans to ensure regular cleaning and prevent issues before they arise.
What size of grease trap do I need for my business?
The size of the grease trap depends on your business type, kitchen volume, and local regulations. A professional can help determine the right size based on the flow rate and waste output.
Does a grease trap need preventative maintenance?
Yes, preventative maintenance is crucial to avoid blockages, bad odors, and costly repairs. Regular servicing ensures efficiency and compliance with public health and environmental standards.
