Wastewater systems face persistent challenges from fats, oils, and grease (FOG). Clogged pipes, sewer overflows, and costly maintenance issues can result if they are left untreated.
Rather than providing long-term solutions, traditional treatments often just move grease downstream, creating temporary fixes.
This is where GreaseZilla stands out. Designed to tackle FOG where it forms, GreaseZilla combines biological and thermal processes to break down grease naturally and effectively.
In this blog, we’ll explore how it works, the science supporting its effectiveness, and real-world case studies demonstrating its power.
What is GreaseZilla and How Does It Work?
GreaseZilla is the fastest-acting grease control product on the market, specially formulated to tackle hardened fats, oils, and grease in grease traps, lift stations, and pipelines.
At its core, GreaseZilla is a biological catalyst, containing a blend of grease-digesting hydrophilic bacterial cultures.
Here’s how it works:
- The bacteria break the chemical bonds between long-chain fatty acids and glycerol.
- Once broken down, the bacteria digest the FOG more efficiently, softening and removing deposits faster and more completely.
- Unlike caustic or solvent-based treatments, GreaseZilla does not push grease downstream, reducing the risk of blockages further along the system.
GreaseZilla prevents ongoing maintenance headaches by fully degrading grease in place through a combination of biological action and thermal effects.

Laboratory Validation: WIST Study on FOG Breakdown
The Wisconsin Institute for Sustainable Technology (WIST) at the University of Wisconsin–Stevens Point tested GreaseZilla against a leading competitor and a control across five types of fats: butter, lard, coconut oil, a field sample, and a composite.
| Sample Type | Control (%) | Competitor (%) | GreaseZilla (%) |
| Butter | ~1.3 | 22.5 | 85.2 |
| Coconut Oil | ~1.5 | 36.1 | 56.4 |
| Lard | ~0.7 | 36.0 | 55.0 |
| Composite Grease | ~1.0 | 37.3 | 58.6 |
| Lift Station FOG | ~2.2 | -0.5 | 76.4 |
These results show that GreaseZilla removed 76.4% of FOG from an actual lift station sample within an hour, compared to negligible or even negative results from the competitor. This demonstrates a clear, scientific advantage in both lab and field conditions.
Mechanism of Action: Why FOG Breaks Down, Not Downstream
GreaseZilla operates through a dual-action, biologically driven process:
- Hydrophilic bacterial cultures digest grease deposits directly.
- A fast-acting biocatalyst accelerates the breakdown of hardened FOG.
The result is irreversible biodegradation, avoiding the downstream displacement common with polymer- or coagulant-based treatments.
Additional benefits include:
- Softening grease deposits on lift station walls
- Suppressing hydrogen sulphide odours, improving workplace safety and environmental conditions
Supplementary Scientific Context
While much of the research comes from international sources, the science is directly applicable to Australian wastewater systems.
Conventional treatments using polymers and flocculants often create sludge, moving the problem downstream. GreaseZilla avoids this by fully breaking down FOG biologically, supporting cleaner discharge and protecting infrastructure.
Science-Driven Advantages of GreaseZilla
| Scientific Advantage | Explanation |
| High fat removal rates | Up to 85% removal in controlled lab conditions within 60 minutes |
| Strong real-world performance | 76% FOG removal from actual lift station sample |
| Irreversible biodegradation | Prevents downstream sludge buildup |
| Odour reduction | Suppresses hydrogen sulfide and softens hardened grease |
| Regulatory and safety alignment | Reduces SSOs, clogs, and maintenance needs |
Why It Matters: From Lab to Infrastructure
GreaseZilla’s effectiveness isn’t just theoretical. It translates into tangible benefits for wastewater operators:
- Operational effectiveness backed by lab data.
- Environmental alignment supports cleaner discharges without sludge burdens.
- Infrastructure protection means fewer overflows, blockages, and maintenance costs.
By targeting FOG where it forms, GreaseZilla delivers a scientifically validated, sustainable, and scalable solution for grease management.
