Muez Hest designs, manufactures, installs and commissions complete biodiesel plants pretreatment, deacidification, transesterification and glycerin recovery – engineered in India and exported to operators across Southeast Asia, Africa, Latin America and the Middle East. Every plant is built to deliver ASTM, EN and IS-compliant BS100 biodiesel from day one of commissioning.
A biodiesel plant is a linked sequence of chemical and thermal separation stages, not a single reactor. Feedstock quality varies enormously from clean virgin vegetable oil to high-FFA used cooking oil and acid oil and the plant has to be engineered around the feedstock actually available, not a generic assumption. Get the pretreatment and deacidification stages wrong and every downstream unit inherits the problem.
Muez Hest’s turnkey scope covers the full process train: feedstock pretreatment, deacidification, esterification, transesterification, glycerin separation and purification, biodiesel washing, distillation and methanol rectification. Every plant is engineered to maximise FAME yield and produce biodiesel that adheres to ASTM D6751, EN 14214 and IS 15607 – the three international quality standards that determine whether a fuel is actually usable in commercial diesel engines.
Scope runs end to end: feasibility and process design, detailed engineering, in-house manufacture, export logistics, civil execution supervision, mechanical erection, commissioning, operator training and post-commissioning technical support engineered in India for deployment across international markets.
Mass balance and yield modelling built around your actual feedstock mix, not a generic assumption.
Pretreatment towers, reactors, separators and distillation columns fabricated in-house.
Civil supervision, erection, piping, instrumentation and control system integration on site.
Performance runs against ASTM/EN/IS specification, operator training, documented SOPs.
Byproduct crude glycerine refined into a saleable Pharma-Grade output, not discarded as waste.
Standards & compliance
Biodiesel that doesn't meet fuel-quality specification isn't a discount product — it's unusable in a commercial diesel engine. Every Muez Hest plant is engineered to produce biodiesel against three internationally recognised standards.
Fuel quality specification
A biodiesel refinery plant exists to hit one target: fuel that meets international specification, not just fuel that burns. The table below is the published EN 14214 / IS 15607:2022 specification — the regulatory bar, not a proprietary Muez Hest claim. Every compliant biodiesel plant has to deliver against these figures; Muez Hest engineers to clear them with margin.

A complete biodiesel facility is assembled from the ten units below, in sequence. Each can be supplied standalone or integrated into a full turnkey line.
— Raw material strategy
Feedstock is the largest line in a biodiesel plant's operating cost, and availability shifts with season and region. Muez Hest plants are engineered across two feedstock categories, so operators aren't locked to a single input.
High-FFA feedstock is precisely what most conventional transesterification routes struggle with the free fatty acids react with catalyst to form soap instead of biodiesel. That's why deacidification and esterification exist as dedicated upstream stages in the Muez Hest process train, rather than an afterthought bolted onto a low-FFA-only plant.
Selecting a biodiesel plant manufacturer is not a one-time equipment purchase – it’s a 15 to 20 year operating commitment. The plant you commission has to keep meeting fuel-quality specification, keep running on whatever feedstock is actually available that season and keep paying back capital long after the sales conversation is over. That’s the standard Muez Hest is built to be evaluated against.
One engineering team across the entire oils-to-fuel chain
Muez Hest designs solvent extraction, edible oil refining, oleochemical and biodiesel plants under a single in-house engineering practice, not as separate business lines. A biodiesel line added to an existing extraction or refining facility is engineered by people who already understand the upstream asset, not handed to a subcontractor learning it from scratch.
Feedstock flexibility engineered in, not bolted on
Dedicated deacidification and esterification stages mean high-FFA feedstock – waste oil, acid oil, distillate isn’t a limitation, it’s a planned input.
Byproduct treated as revenue, not waste
Crude glycerine refined to 98.7%+ Pharma-Grade rather than sold at technical-grade prices.
Standards engineered from commissioning, not retrofitted later
ASTM D6751, EN 14214 and IS 15607 compliance built into the process design from day one, including the BIS certification that determines OMC eligibility in India.
Turnkey accountability, start to finish
Feasibility, detailed engineering, in-house fabrication, export logistics, civil supervision, erection, commissioning and operator training under one contract, not stitched together across multiple vendors.
A track record built across every inhabited continent
450+ projects and 30+ years of oils and fuels engineering, commissioned across Asia, Africa, Europe, the Americas and the Middle East.
Whether the scope is a single deacidification tower, a complete transesterification line, or a full turnkey plant with glycerin valorisation, our engineering team can work through feedstock, capacity and standards compliance with you before any commitment.
India’s decades as the world’s largest vegetable oil importer built genuine engineering depth in oils and fats processing – deacidification, high-vacuum distillation, glycerin handling the exact core skillset a biodiesel plant demands, refined at industrial scale long before biodiesel itself became a priority. That depth typically comes at a lower installed cost than sourcing from a European process licensor, without trading away process capability, which matters directly to project ROI in price-sensitive markets across Southeast Asia, Africa and Latin America. India’s own National Policy on Biofuels and its role in the Global Biofuel Alliance keep domestic manufacturers continuously engineering real, operating plants rather than only exporting designs, so the engineering is pressure-tested before it ships. Geographic proximity and English-language technical documentation shorten the distance to buyers across these same regions. Muez Hest carries all of this further: 30+ years and 450+ commissioned plants turning that national capability into a working, ASTM/EN/IS-compliant plant on your site, not just a design on paper.
Trusted worldwide, Muez Hest provides end-to-end turnkey solutions delivering fully operational plants from design to delivery.
The questions procurement and technical teams most often raise before a biodiesel plant enquiry →
A biodiesel plant is an industrial facility that converts vegetable oils, animal fats and used cooking oil into biodiesel, known technically as Fatty Acid Methyl Ester (FAME), through a linked sequence of pretreatment, deacidification, esterification, transesterification and purification stages, producing biodiesel fuel and refined glycerin as a co-product.
Plants are engineered for two feedstock categories. Low FFA feedstock includes used cooking oil, tallow, and vegetable oils such as CPO, soybean, sunflower and palm stearin. High FFA feedstock includes waste oil, high-FFA vegetable oil, free fatty acid distillate and acid oil. Multi-feedstock capability lets operators switch inputs as raw material prices move.
Timelines depend on capacity, scope and site readiness. A typical turnkey project moves through feasibility and process design, detailed engineering, fabrication, shipment, erection, and finally commissioning with operator training. Civil readiness and utility availability at site are usually the largest variables in the schedule.
Yes. Scope covers export logistics, international code compliance, civil execution supervision, mechanical erection, commissioning, operator training and post-commissioning technical support, with biodiesel plants engineered in India for deployment across Southeast Asia, Africa, Latin America and the Middle East.
Cost is driven by capacity, the number of process units in scope, feedstock flexibility requirements, degree of automation, the standards the plant must certify to, and whether the scope is equipment supply only or full turnkey execution with civil works and utilities. A budgetary estimate is prepared after the feasibility discussion.

Most biodiesel problems don’t start in the reactor, they start in the raw material. Feedstock with high free fatty acid content reacts with catalyst to form soap instead of biodiesel, which can stall conversion and contaminate the glycerine byproduct. That’s why Muez Hest treats feedstock conditioning as a dedicated stage rather than a footnote: deacidification reduces FFA to below 0.1 percent before the feedstock ever reaches the transesterification reactor.
A standard single-stage transesterification route struggles with high-FFA inputs such as used cooking oil, acid oil and free fatty acid distillate. Muez Hest routes these through dedicated pretreatment, deacidification and esterification stages before transesterification, rather than forcing difficult feedstock through a process designed for clean virgin oil. Feedstock flexibility isn’t a technical bonus here, it’s what determines whether the plant can actually run on the raw material available in your market.
Methanol is a direct, ongoing cost on every batch. A poorly designed recovery system increases fresh methanol consumption, utility load and downstream purification cost, all of which erode margin on every tonne produced. Muez Hest’s methanol rectification plant recovers and purifies methanol from both the transesterification and washing stages through fractional distillation, so it’s reused in production rather than repeatedly bought and lost.
Poorly handled glycerine is either a disposal cost or, at best, a low-value technical-grade sale. Crude glycerine leaving the plant typically contains 40 to 60 percent glycerol mixed with methanol, water and salts. Muez Hest’s purification, evaporation, distillation and activated carbon bleaching train refines this to 98.7 percent purity Pharma-Grade Glycerine, turning a byproduct most plants treat as waste into a second saleable output.

Ask for the numbers, not just the standard’s name. Muez Hest plants are engineered to produce BS100 grade biodiesel against the full EN 14214 / IS 15607 specification – density, viscosity, flash point, sulphur, cetane number and nine other parameters not just a general claim of ASTM or EN compliance.
