Radhe Enterprise manufactures high-performance bentonite absorbent granules designed for industrial spill response, environmental remediation, water treatment, and workplace safety applications. Our calcined and activated bentonite absorbent granules deliver 350%+ liquid absorption capacity by weight — rapidly uptaking oils, hydrocarbons, solvents, acids, alkalis, and aqueous chemical solutions while maintaining granular integrity for efficient collection and disposal.
Industrial absorbent bentonite is produced through controlled thermal calcination that develops a high-porosity internal structure within each granule. This porous structure provides the capillary network necessary for rapid liquid uptake and stable retention, distinguishing industrial-grade absorbent from basic clay granules that lack the engineered porosity for effective spill response. The resulting product is chemically inert, non-toxic, non-flammable, and safe for use in proximity to personnel and equipment.
If your EHS team, maintenance operation, or environmental contracting business requires bentonite absorbent granules for oil spill cleanup, chemical spill containment, workshop floor maintenance, or industrial water treatment applications, Radhe Enterprise delivers from our Bhavnagar, Gujarat facility with consistent absorption specifications, flexible packing (10 kg to 1 MT jumbo bags), and pan-India or export delivery capability.

Oil Spill Response — Rapid Hydrocarbon Containment with Bentonite Absorbent
Bentonite absorbent granules are deployed as a primary response material for hydrocarbon spill containment in industrial facilities, fuel storage depots, refinery operations, transport terminals, and marine environments. When applied to an oil or fuel spill, the calcined clay granules immediately begin absorbing the hydrocarbon through capillary action into their porous internal structure, encapsulating the liquid within the granule matrix and converting it from a flowable liquid to a solid granular waste that can be swept, collected, and disposed of in accordance with hazardous waste regulations.
The absorption process is rapid — typically reaching saturation within 2–5 minutes of application for light to medium hydrocarbons (diesel, petrol, hydraulic oil, lubricating oil). For heavier hydrocarbons (crude oil, bunker fuel, bitumen), the absorption rate is slower but ultimate capacity remains above 350%. The spent absorbent can be disposed of through incineration (the clay fraction is non-combustible and reduces the calorific value of the waste stream) or landfill disposal where the contaminants are stabilized within the clay matrix, reducing leachate generation compared to free-liquid disposal.
Chemical Spill Containment — Acid, Alkali and Solvent Absorption
Beyond hydrocarbons, bentonite absorbent granules are effective for containment and cleanup of a wide range of chemical spills including: dilute mineral acids (sulphuric, hydrochloric, nitric), alkalis (sodium hydroxide, potassium hydroxide), organic solvents (acetone, ethanol, isopropyl alcohol), aqueous chemical solutions, and process water containing dissolved contaminants. The granules are chemically inert across the pH range of 3–11, maintaining structural integrity and absorption capacity without degrading or generating hazardous reaction by-products.
For facilities handling multiple chemical types — laboratories, chemical processing plants, pharmaceutical manufacturing operations, and waste treatment facilities — bentonite absorbent provides a universal first-response material that can be applied without the need for spill-type identification before application. The absorbed chemical waste is stabilized within the clay matrix, reducing vapour release and containment during collection and transport. For aggressive chemicals (concentrated acids above 30%, strong oxidizers), we recommend compatibility verification through bench-scale testing before full-scale adoption.
Workshop Floor Maintenance and Industrial Housekeeping
Workshop floors in manufacturing plants, automotive service centres, machine shops, and equipment maintenance facilities accumulate oil drips, coolant spills, solvent residues, and aqueous cleaning waste that create slip hazards and environmental compliance concerns. Bentonite absorbent granules provide a practical daily housekeeping solution: apply to wet areas, allow 2–5 minutes for absorption, sweep clean. The granules do not leave a slippery residue on floor surfaces and do not generate the airborne dust clouds associated with alternative absorbents like diatomaceous earth or silica-based products.
For routine floor maintenance programs, we supply absorbent in dispenser-friendly bags (10 kg and 25 kg) that fit standard industrial absorbent dispensing stations and wall-mounted cabinets. Bulk supply for large facilities can be arranged on scheduled monthly delivery cycles, with per-bag pricing that undercuts packaged consumer-grade absorbent products by 30–50%.
Water Treatment and Wastewater Applications — Natural Flocculation and Adsorption
Bentonite's high surface area (600–800 m²/kg after activation) and negative surface charge make it an effective natural flocculant and adsorbent in water and wastewater treatment processes. In clarification stages, bentonite particles attract and bind suspended solids, colloidal particles, phosphates, and dissolved organic compounds through electrostatic interaction and physical enmeshment — forming settleable flocs that can be removed through sedimentation or dissolved air flotation.
Industrial applications include: heavy metal removal from electroplating and metal finishing wastewater (adsorption of lead, cadmium, chromium, copper, zinc onto clay surface sites), oil-water separation in refinery and petrochemical wastewater (bentonite adsorbs emulsified oil droplets), colour removal from textile dye effluents (adsorption of cationic dyes onto the negatively charged clay surface), and sludge conditioning for improved dewaterability in municipal and industrial sewage treatment plants.

Frequently Asked Questions
What is the liquid absorption capacity of industrial bentonite absorbent granules?
Our calcined bentonite absorbent granules achieve 350%+ absorption by weight — meaning each kilogram of granules can absorb 3.5+ kilograms of liquid (oil, water, solvents, or dilute chemicals). Actual capacity varies by liquid viscosity and density, with light hydrocarbons and water at the higher end of the range and viscous oils at the lower end.
Is bentonite absorbent suitable for both oil and chemical spills?
Yes. Bentonite absorbent granules are effective for hydrocarbons (diesel, petrol, engine oil, hydraulic oil, crude oil), organic solvents (acetone, alcohols, ketones), dilute acids and alkalis (pH 3–11), and aqueous chemical solutions. The granules are chemically inert and do not degrade or generate hazardous by-products upon contact with most industrial chemicals. For concentrated acids (>30%) and strong oxidizers, we recommend pre-testing for compatibility.
What is the difference between calcined bentonite absorbent and basic clay granules?
Calcined bentonite is thermally treated at high temperatures to develop internal porosity — creating the capillary network necessary for rapid liquid uptake into the granule interior. Basic (non-calcined) clay granules have minimal internal porosity and absorb primarily through surface wetting, resulting in much slower uptake and lower total capacity. The calcination process is what distinguishes industrial-grade absorbent from simple clay granules.
How should spent bentonite absorbent be disposed of after spill cleanup?
Spent absorbent classification and disposal depend on the absorbed substance. For non-hazardous spills (water, coolant, food-grade oils), the spent material can be disposed of as non-hazardous industrial waste. For hazardous substance spills (fuels, solvents, chemicals), the spent absorbent must be disposed of as hazardous waste in accordance with applicable environmental regulations. The clay matrix stabilizes the absorbed contaminants, reducing leachate generation compared to free-liquid disposal.
What is the price of bentonite absorbent granules from Bhavnagar?
