Sustainable Technology
Renewed Carbon has developed and continues to innovate reliable technologies that enable the delivery of sustainable products based on renewable resources. We have deep expertise in tailoring solutions for specific market needs.
As a solution innovator Renewed Carbon applies the most appropriate technologies to optimally address each biomass processing opportunity. The core technologies upon which we base our solutions are Pyrolysis and wet and dry Anaerobic Digestion.
To do this we bring years of R&D, testing and piloting to construct operating frameworks that can reliably meet market requirements.
Pyrolysis
Simple yet technically challenging
Pyrolysis involves heating an organic material, such as biomass, in the absence of oxygen. It is this which enables the biomass to be processed into different outputs which would not be possible if there was combustion. Instead of burning and reducing the biomass to an ash and emitting CO2 the cellulose, hemicellulose and lignin compounds are broken down into char, bio-oil and syngas. The distribution of these outposts is a function of the feedstock used and the process parameters. Higher temperature rates deliver greater yields of bio-oil, lower ones favour biochar. The process can be self-sustaining using syngas or other outputs to supply the required energy.
Renewed Carbon has invested heavily in testing and developing the operating parameters necessary to reliably deliver a range of sustainable biomass derived products.

Anaerobic Digestion
Organic matter, such as animal or food waste, can be broken down to produce biogas and biofertiliser. This process, knowns as anaerobic digestion, happens in the absence of oxygen in a sealed, oxygen-free tank called an anaerobic digester.
Bacteria break down the waste and in doing so generate biogas. That biogas is mostly comprised of methane, the primary component of natural gas. The non-methane components of the biogas are removed so the methane can be used as an energy source.
Some types of organic matter break down more easily than others. Generally, the more digestible the organic matter the greater the quantity of biogas that can be produced. This is the case with animal manures.
Codigestion occurs when anaerobic digestion is used to break down multiple types of organic waste in one anaerobic digester. Organic wastes that may be used in codigestion with manure include food and food processing wastes; fats, oil and grease from restaurant grease traps; energy crops; and crop residues. Codigestion can increase biogas production from low-yielding or difficult-to-digest organic waste.
Anaerobic digesters are particularly valuable in effectively handling the waste from animal farms.

Technology Development
The initial pilot plant
The technology which underpins Renewed Carbon's business has been developed, tested and trialled over many years. A pilot plant was constructed in 2004 near Newcastle, NSW to prove the technical viability of the technology.
Subsequently and using the knowledge gained from the pilot operation the Company developed a design suited to large-scale commercialisation.

Continuing Research
Our first test rig
This test rig was used to understand detailed technical specification from differing pyrolysis methods on multiple species of biomass.
The second pilot plant
Our second pilot plant is used to test innovative combinations of Biomass and minerals.The rigorous testing and analysis of the designs and product output of the test and 2 pilot plants has informed our commercial scale design ensuring optimised product production.
