SRS International provides complete turnkey biodiesel refinery solutions — from initial planning and permitting through engineering, fabrication, installation, startup, and ongoing support. With decades of experience, we guide you through every step to build a profitable, efficient, and ASTM-compliant biodiesel plant.
Choosing the right plant size is critical to success. We help you balance your budget, available land, feedstock supply, logistics, and government incentives to design a facility that delivers maximum value and return on investment.
Site selection significantly impacts long-term profitability. Key factors include proximity to feedstock suppliers, customers, transportation corridors (truck, rail, barge), and available utilities (natural gas, electricity, water, and sewage). We assist with site evaluation to minimize transportation costs and maximize operational efficiency.
We provide full engineering documentation, mass and energy balance data, and support materials to help streamline air, water, and local permitting processes, saving you time and reducing delays.
Our multi-disciplinary team of over 40 engineers (Process, Chemical, Mechanical, Electrical, Civil, Structural, and Controls) delivers custom-designed solutions tailored to your specific requirements — never a one-size-fits-all approach.
We work closely with you to select the right equipment for high-FFA pretreatment, transesterification, methanol recovery, glycerin purification, distillation, and polishing — all optimized for your feedstock and production goals. We also help you explore profitable opportunities such as glycerin purification systems.
Our equipment is delivered as skid-mounted, pre-assembled modules with single-point connections, dramatically reducing installation time from weeks or months to just days. We provide detailed installation support and can supply on-site engineering supervision as needed.
Our systems are engineered with quality and BQ-9000 certification in mind. We guarantee ASTM D6751-compliant biodiesel production and provide the documentation, procedures, and training needed to help you achieve and maintain certification.
We perform comprehensive testing and validation before turnover. Our team then provides thorough hands-on training for your operators and maintenance staff. We also offer ongoing remote support via secure connection to your control system.
We offer optional full plant management services, including staffing, daily operations, maintenance, quality control, and regulatory compliance — allowing you to focus on business growth while we handle day-to-day operations.
Our designs are built for expandability and feedstock flexibility. Whether you want to process new high-FFA materials or increase capacity, SRS systems are designed to grow with your business.
