KESSLER's Pongamia Plantations: A Source for RNG and RLNG

עודכן: 6 בדצמ׳ 2023

Biogas (RNG) is produced during anaerobic fermentation of organic waste, during which bacteria break down organic substances into simple compounds. This gas is a mixture of methane (40-85%), carbon dioxide (30-55%), and other gases in trace amounts produced in controlled processes of anaerobic biomass decomposition.

In AD processes, the following can be used as a raw material for biogas production:

  • Waste from food production (vegetable waste, fruit pomace, fat waste, and many others),

  • Waste from animal production (slurry, manure, dry excrement),

  • Waste from plant production (grain waste, feed waste),

  • Energy crops from particular purpose crops (cereals, including corn, root crops, rapeseed, and others).

Renewable natural gas (RNG) is a sustainable alternative to natural gas. It can be processed similarly, which means utilities can use it on the same pipelines and other infrastructure without any problems. It is also a low-carbon energy solution that does not require fossil fuels to generate energy.

Renewable natural gas has a future in energy and could help solve the world's current waste problem. Diverting waste from landfills and agricultural activities could reduce lifecycle greenhouse gas emissions by 50% while creating new green jobs and shifting the energy industry away from fossil fuel production. Because RNG can be easily implemented into the current natural gas infrastructure, it can be a cost-effective way to deal with waste while providing renewable, low-carbon energy to the grid.

Also, and this is very important, as an increasing number of companies engage in various decarbonization solutions, renewable natural gas may play an increasingly important role in the transport sector - both as a direct replacement for diesel and gasoline and as a raw material for bio-based products used in difficult to reductions, high-emission sectors.

Use as a feedstock in developing bio-based products such as biohydrogen is an emerging source of demand for RNG. Bio-based products will be vital in enabling the transport industry's transition to a low-carbon future.

We've consistently emphasized our continuous exploration of elite Pongamia tree varieties. Today, we're thrilled to share further insights from our ongoing research. KESSLER, working hand in hand with ARO, remains committed to perfecting a model that maximizes the use of our Elite Pongamia fruits in energy, fuel, and oleochemical processes in such a way that the finished products are low-emission and friendly for use in these processes.

For the AD process, the quality of the raw material is of fundamental importance due to the RNG efficiency and the process itself, namely its stability. The main threats to such a process are the content of heavy metals, chlorine content, too high nitrogen content, high content of mechanical impurities, and high water content. With the so-called complex process of raw materials, the AD system's technological design is different, resulting in increased investment outlays for the process itself. Also, one of the most critical factors affecting the stable operation of the installation is the physiochemically stable raw material delivered in constant and appropriate quantities.

Our efforts in this field revolved around utilizing the byproducts derived from the fruits of our genetic strains to generate RNG and RLNG. This byproduct emerges during the production of oil and proteins from our fruits. Classified as agricultural waste, it stands as an emission-free raw material.

Undoubtedly, the most paramount advantage of this waste is its physicochemical stability and the excellent composition of carbohydrates and starch content. While conducting numerous laboratory tests, we can confirm that this waste does not contain heavy metals or chlorine and retains minimal sulfur content (minimal H2S emissions in the process). In terms of composition, it resembles the best agricultural raw materials used for this purpose, with one remark: our raw material is waste!!!. With such a composition of our raw material, the efficiency of RNG in the process will be the highest, and thanks to the quality, the AD technological process itself will be the cheapest.

One of KESSLER's concepts will be to build an AD installation right next to a commercial plantation in such a way as to use the produced RNG to generate renewable energy to power other production processes or to sell it to its customers in the form of RLNG.

At this juncture, it's crucial to emphasize that our commercial Pongamia plantations use arid and severely degraded areas. This approach enhances the value of our products, including RNG, Pongamia oil, solid waste biomass, and Carbon Credits, ensuring their utmost potential.
