Argent’s waste-based biodiesel is a distilled product that can be directly blended with conventional diesel and used as a fuel, typically in trucks, buses, vans and cars. In this way it contributes proportionately to the lowering of CO₂ emissions of the vehicles it powers
Watch Our Process
From Waste to Biodiesel
Pre-treatment
The severely degraded fats & oils are processed to remove impurities in order to enhance biodiesel yield, decrease in-line process and maintenance issues as well as decrease overall chemical usage.
Biodiesel production – Step 1
Any free fatty acid present in the oil is reduced to a manageable level limiting issues further down the process. Argent’s capability to do this is one of the main reasons why we can handle severely degraded oils such as FOG and grease trap waste.
Biodiesel production – Step 2
The oil is reacted again, under different conditions, and at this stage the vast majority of the biodiesel is synthesised. Any oil that is not converted at this stage is collected and put back into the process, ensuring a high conversion to biodiesel.
Side product creation
The discharges from the previous two steps are collected and then reacted together; yielding our fertiliser and glycerine side products.
Distillation
Post-reaction the crude biodiesel is put through a distillation column as a final polish to ensure Argent Energy produces biodiesel of a consistent high quality. At the distillation step, biofuel oil is also collected as a by-product which is used as marine fuel making sure that very little waste is produced overall during the process.
Completion
The biodiesel undergoes comprehensive testing and analysis, and is then ready to go.
Applications
Road Transport
Fuelling road transport is the most common use for biodiesel but it is also a good carbon-saving alternative fuel for use in heating and power generation.
Applications
Heating
More and more eco-conscious businesses are turning to this renewable, clean-burning fuel to power boilers for offices, factories and schools. With some adjustments, it may serve as a replacement for traditional heating oil and is much more environmentally friendly.
Applications
Marine Fuel
Our distilled biodiesel can be used as a marine fuel for inland barges and seagoing vessels. The heavier fraction of our distillation process can also be used as marine fuel after further refining. More information on this Biofuel Oil (BFO) can be found here
Applications
Raw Materials
At Argent Energy, we use a variety of waste as raw materials for our biodiesel production. We strive to reuse any waste oils or fats that can no longer be used in the food or feed sectors and give them a new life. The feedstock list includes:
High Free Fatty Acid (FFA) oils and fats
Material with a high FFA which is highly contaminated and predominantly a waste from edible oil production and refining.
Animal Fat (Tallow)
We exclusively use waste animal fat denoted as category 1 and 2, which cannot be used for food or animal feed.
Used Cooking Oil
Waste oil that has been used for cooking and then collected from restaurants and households.
Effluent Ponds
Liquid waste oil recovered from effluent ponds.
Food waste
Waste from various food production processes including bakery wastes which are high in oil content, contaminated sauces and condiments or oil extracted from food waste collection
