The Supercritical (Super) biodiesel process is patented and was developed by Jatro Renewables over a two year period.
The process differs substantially from “traditional” methods of producing biodiesel in that it uses no catalyst and is able to process up to 100% free fatty acid (FFA) feedstocks.
The process is also easy to operate as without the catalyst no soap can form eliminating the clean-up labor and system down time cost.
Also, by not needing a catalyst, the by-product glycerin (8-11% of total production) is worth about double the value of glycerin produced at traditional biodiesel facilities.
The Super process reacts the feedstock and methanol at approx. 700C. and under about 2,700 psi pressure.
Final distillation removes sterols and metal contaminates and renders the biodiesel perfectly clear.

The above includes land, building, roads, capital for feedstock and chemicals.
Projects well ahead of expectations, deduct ~5% of plant cost estimate.
The final cost estimate will vary depending on a number of factors; however,
we have built into the estimates contingencies to minimize coming in over budget..
10 to 15 months from contract signing date to plant commissioning, EPA
and LCFS (for California and Oregon), registration of ASTM 6751-15 biodiesel production and fuel pathway approvals.
All equipment that is part of the project covered by vendors’
warranties which typically range from 60 days to 5 years or more.
Warranty starts when the equipment is received on-site.
Additional warranty can be bought directly from vendors
Quality: Biodiersel, ASTM 6751-15. Renewable Diesel, ASTM D975

ENGINEERING & LICENSING
1. Designing and permitting of the entire facility (including equipment,
tank farm placement, pipeline layout etc.)
2. Working with customer’s civil engineering firm to design the
plant building structure (if required), roads and rail
3. Managing the project with plant manager for mechanical, electrical
and automation coordination
4. Soliciting one or more quotes for certain equipment
5. Provide PFDs, simulation data (ChemCAD), P&IDs, and 3D drawings
for entire facility
6. Operational manuals in the form of “functional requirement.” This
includes: process description, operational logic and start and stop
procedures. (Typically, each facility has specific requirements for
7. One-time licensing fee (included in figures above).
Jatro Renewables Typical Plant Cost Overview
Certificate of Analysis (Typical)
A typical chemistry lab will test about six of the required 18 test s for ASTM 6751, and for each batch of fuel. The balance of analysis is sent out to a 3rd party lab on a regular basis, but not for every fuel truck or rail car load leaving the plant (see below).
The total cost of the project (as listed above) includes the estimated costs for the land, building/structure, building modifications/improvements, insulation, grounding, pump pads, storage containment walls, and any outside additions such as laying of the road or a rail line (with certain limitations). It also, includes the total all-in project costs for the Process Equipment, including Storage tanks and all Labor.
Jatro Renewables suggests using a local engineer or a permitting consultant to work with the local environmental or regulatory agency.
With our prior experience in implementing projects in various states in the U.S (MI, OH, NE, IL, NY, PA, MD, WI, and CA) as well as outside the U.S, we can provide guidance on the engineering, and permitting issues from EPA and other local regulatory bodies on both process equipment and electrical/automation instrumentation.
Currently, Jatro Renewables has two genres of plants it offers clients:
Within about three years, new and existing Supercritical and RHD plants will use oils from cellulosic materials such as woody biomass, grasses and municipal solid waste.
These oils will be provided by 3rd party sources or from equipment supplied by 3rd party vendors. It is not anticipated any major design changes to existing or new plants will be required.

Since the advent of the internet and loss of newspaper subscription and greatly reduced 1st Class Mail use, the paper industry are looking to other industries to replace use of their feedstock, trees. Use of paper is down about 60% since 1998 . . . and still shrinking.
