A new bio-based hydrophobic oleophilic foam that can absorb 80X its weight in petrochemicals. It soaks up oil and repels water. It's durable, reusable, and suitable for a variety of applications.

2. Approximately 706 million gallons of waste oil enter the ocean every year,
with over half coming from land drainage and waste disposal.
Offshore drilling and production operations and spills or leaks from ships
or tankers typically contribute less than 60 million gallons every year.
Routine maintenance of ships (140 million gallons/year), hydrocarbon
particles from onshore air pollution (95 million gallons/year), and natural
seepage from the sea floor (55 million gallons/year).
20-40% of oil evaporates, and the rest emulsifies in the water forming
a brown / black mousse; heavier parts of the oil sink, and some of the oil
biodegrades eventually.

3. TECHNOLOGIES TO
SEPARATE OIL FROM WATER
Floating oil can be removed by oil skimmers, and in the ocean, floating oil
spills have been contained by booms and skimmed off the water surface;
rough ocean surface can make oil skimming very difficult; skimming only
removes non-emulsified oil.
Emulsified oil can be removed using hydrophobic foams, but their
capacity is limited, typically 10-30 times the foam weight. Further, the oil
is removed by physically squeezing the foam, which results in mechanical
degradation of foam material after a few cycles.
Ultra-filtration membranes have been used in oil-water separation, but
they are expensive to buy and operate; fouling of membranes results in
performance degradation.

6. APPLICATIONS OF OIL ERASER
A Simple, cost-effective technology to separate oil from water.
WATER TREATMENT:
Reticulated Oil Eraser foam can clean wastewater and retention
ponds at a fraction of the cost.
CONTAINMENT:
In addition to surface booms, Oil Eraser subsurface nets can be
used as barriers to prevent spills from damaging beaches and
wetlands.
PREVENTION:
Use Oil Eraser foam as a first line of defense against industrial
pollution – containing the leak before it becomes an environ-
mental hazard.

7. APPLICATIONS OF OIL ERASER
RECLAMATION:
Captured oil can be extracted and Oil Eraser foam can be
re-used indefinitely– our process does not involve wringing,
squeezing or otherwise damaging the foam.
CLEANUP:
Oil Eraser even works on emulsified oils – without introducing
detergents to the environment.
FILTRATION:
Oil Eraser can be used as a filter in waste pipes to collect
petroleum waste products including oil, diesel, chlorobenzene
and more.

8. APPLICATIONS OF OIL ERASER
The most challenging part of oceanic cleanup is subsurface oil
– what looks like a brown cloud, emulsified by wind and
waves. Oil Eraser, suspended in plastic cages, forms a
barrier, containing this hazard. Water passes through but
petrochemicals are captured by the foam.
Neutrally bouyant cages trap underwater oil.

11. APPLICATIONS OF OIL ERASER
It’s not a foam ... it’s any foam.

12. APPLICATIONS OF OIL ERASER
Reclamation process saves water, oil, and foam
No wringing, squeezing or spindling. Oil Eraser uses a
proprietary eco-friendly solvent to release and reclaim
captured oil. Because this process minimizes mechanical
wear, Oil Eraser can be re-used indefinitely.
