Mechanism of SPILLOFF:
  • When broadcast over a crude oil or fuel spill in marshes, wetlands, mangroves or along shorelines, the specially processed absorbents in SPILLOFF immediately begins to soak up the spill and to encapsulate it with high efficiency.
  • SPILLOFF is designed to absorb oil five times it’s volume.
  • This absorption may take 30 minutes time depending on the thickness of the oil film and the thickness of the SPILLOFF.  
  • A food grade gelling agent present in SPILLOFF then activates in the water, providing some tackiness for increasing its ability to cleanse oil from the blades of wetland grasses and the roots of mangroves.
  • This takes about 60-120 minutes.
  • Within hours, the third component of SPILLOFF consisting of large numbers of high performance, oil degrading microbes and timed release microbial nutrients begin to diffuse from SPILLOFF into the oil layer to quickly begin accelerating the natural biodegradation of the contaminant. 
  • This process will continue forever, as SPILLOFF possesses the ability to provide ambient conditions for the survival of hydrocarbon degrading microorganisms that are present in SPILLOFF and from the surrounding environment, as long as suitable moisture and the food (Oil) are available and until the hydrocarbon has been reduced to carbon dioxide and water.
  • Once the food source has been depleted, the remaining microbes then self-remediate.
  • This results in clean and clear water without traces of hydrocarbons, toxins and pathogens

Primary Mode of Action of SPILLOFF is to utilize Phenol; benzene; toluene; other aromatic hydrocarbons with hydroxylated, nitrogenated groups; octane; ethane; other short-chained alkyl hydrocarbons.

Secondary Action of SPILLOFF is to degrade Salicylic acid, biphenyl; xylol; phenoxy alcohols; mineral oils; lubricating oils, kerosene; surfactants; gasoline; pentachlorophenol; Intermediate length alkyl hydrocarbons and alcohols, fatty acids, benzolic acid, citrus oils.​
Targets of SPILLOFF: 
  • Absorb oil or fuel spill on surface water, marshes, mangrove, beach or shoreline.
  • Biodegrade the oil or fuel spill into safe products.
  • To be left in place in the spill site (in situ) to accelerate the environmentally safe biodegradation of that hydrocarbon through the use of controlled bio-augmentation.  
Hydrocarbon Spill Management


A ratio of diluted SPILLOFF 1:1 in terms of mass of Hydrocarbons is usually used.
For example, if the weight of the oil spill is estimated to be 1 kg, then the amount of diluted SPILLOFF that needs to be used is 1 kg.

Application Rates
For Marsh, Mangrove, Wetland and Water Spills:
If the spill is reasonably fresh and has spread out into a thin layer (>0.5mm) over the water surface, apply SPILLOFF at the rate of: 1 kg in 20 L water and 1 Kg Cow dung and allow for 12 hours with an aerator  and blend this with 4 kg Psyllium husk and broadcast on per 100 m2

For weathered or heavily oiled surfaces, up to double that dose is suggested.

For Intertidal Zone, Shoreline, Beach and Riverbank
If the spill is reasonably fresh and has oiled the shoreline, rocks, sand or gravel in a thin layer (>1 mm), apply  SPILLOFF at the rate of : 1 kg in 5 L water and 1 Kg Cow dung and allow for 12 hours with an aerator  and blend this with 1 kg Psyllium husk and broadcast on per 25 m2

For heavily oiled surfaces or wave tossed shorelines, double that dose. 
Apply SPILLOFF at low tide to the wet, exposed beach sand, gravel or rock.
Salient Features of SPILLOFF
  • A oleophilic super nutrient that attracts microorganisms, in the local environment which possess the ability to convert hydrocarbons (such as oil and fuel) into water and other harmless byproducts; in addition to the live load of one specific strain of Pseudomonas present in the SPILLOFF.
  • Heavy metals like Cadmium and Lead are absorbed.
  • SPILLOFF can be used in situ and ex situ.
  • SPILLOFF can be used in Marshes, Mangroves, Wetlands, and Shorelines and also over rivers and oceans.
  • The added microorganisms are made resistant to naturally occurring toxins or predators in the environment,
  • The concentration of the contaminant is so matched by the dose administered, that it will support the growth of the inoculants,
  • The inoculant is possessing the ability to move through the environment to the contaminant
  • The usage of SPILLOFF as part of an active biotreatment program will significantly accelerate natural recovery from a spill.
  • When SPILLOFF is used, oil spills slowly disappear from the environment primarily through natural biodegradation, evaporation and oxidation. 
  • With SPILLOFF 4 to 8 fold increase in biological oil removal rates can be achieved under well managed conditions. 
  • If limited sections of shoreline, mangrove, wetland, marsh and/or floating slick are treated intensively with SPILLOFF; a reduction in residual oil mass of over 75% is feasible within 6-7 months, with a portion of the spill evaporating and a portion biodegrading. 
  • SPILLOFF is equally effective with fresh, salt and brackish waters.
  • SPILLOFF does not contain any genetically engineered microorganisms (GEM).
  • Microbes present in SPILLOFF have a high tolerance for salt.
  • They can withstand higher salt levels than those found in sea water.
  • Microbes present in SPILLOFF have a broad spectrum of metabolic pathways and are thereby able to degrade complex hydrocarbon chains.
  • SPILLOFF can also degrade the soluble BTEX compounds found below the surface of the water.
  • Heavy greases and old residual weathered hydrocarbons with high molecular weights are also degraded by SPILLOFF.
  • Reduction in odors from the spill within 12 hours from the time of application of SPILLOFF.
  • When added to bilge water SPILLOFF rapidly eliminates vapors and odors associated with diesel fuel and gasoline.
  • SPILLOFF can tolerate sodium levels of the treatment area up to 15%.​

Providing Sustainable Green Technology Solutions 

Flagship India


  • Mix SPILLOFF 1 Kg in 20 L water and 1 Kg Cow dung and allow for 12 hours with an aerator on.
  • Then blend with 4 Kg Psyllium husk
  • Then broadcast over the contaminant surface.
  • For even coverage and best results, we recommend application from helicopter, airdrop or shallow boat with powered air blowers to disperse the SPILLOFF. 
  • Ground spotters should be deployed to report on uniformity of coverage. 
  • Apply SPILLOFF until it becomes wet with oil but not saturated. 
  • If free oil is still present, apply additional SPILLOFF until the spill is absorbed.
  • When SPILLOFF comes into contact with the water/oil interface, SPILLOFF will begin to soak up the spill. 
  • If oil has coated mangrove roots or wetland grasses, tidal action or wave action will assist SPILLOFF in cleansing root and grass surfaces.
  • Repeat the procedure after about 3 weeks if free oil is still present.

SPILLOFF is available in 1 Kg packing.

Product can be safely stored in temperature ranges of 10 degree to 45 degrees C.
Shelf Life is a minimum of 2 years if stored in a dry place.

  • If using on a land spill, shoreline or beach, water is to be added periodically to keep the SPILLOFF /oil matrix wet. 
  • Rainfall, tidal flushing or manual sprinkling with fresh or salt water is acceptable. 
  • If a water spray is used, direct the water into the air so that it falls in an arc on to the SPILLOFF wetted area like raindrops or mist.

  • For best results, a moisture content of 30 to 40% of the soil's holding capacity should be maintained (this equals around 23% for loams).
  • The soil should be kept moist by adding fresh water.
  • Periodically measure the presence of Ammonia, Nitrates and Phosphates in the water column or from the shoreline runoff. 
  • If the concentration of the N or P falls below 2mg/L or 0.5 mg/L respectively, additional N: P time release fertilizer should be applied. 
  • Measure decreases in petroleum hydrocarbons over time. 
  • When concentration drops to a satisfactory level, discontinue fertilizer and water application.
  • If tidal flushing or water flow causes the treatment site to become re-oiled or the SPILLOFF layer is flushed out, re-apply new SPILLOFF as per the above procedure and application rates.

What is the time frame of SPILLOFF?
It may take from a few hours to several months or longer to the complete degradation of all the hydrocarbons present in the field of application.

It all depends on several factors like:
  • Ability of the microbes to reach the contaminant
  • Availability of nutrients including sodium
  • Availability of oxygen in the area
  • Level of contamination,
  • Non ambient conditions that may prevail in the field of application
  • Quantity and quality of the microbes present
  • Temperature,
  • The initial contaminant,
  • Type of soil, Water surface
  • It is difficult to predetermine the time required for the complete operation.
  • It can range anywhere from few hours for simple gasoline spills to several months for complicated crude oils.

How to evaluate the performance of SPILLOFF?
  • Soil analyses may be conducted periodically to evaluate the treatment program requirements.
  • When measuring the effectiveness of the bioremediation process, using SPILLOFF; TPH analysis is not particularly accurate and may even indicate the presence of a gasoline or diesel fuel when none is there. 
  • A more exacting identification of hydrocarbons in soil and NAPLs can be made using fingerprinting methods such a gas chromatograph followed by a flame ionization detector (GC/FID) (Zemo, Bruyaand Graf, 1995).
