Renewable Fuels Made From Agricultural and Industrial Waste

Aemetis specializes in the production of biofuels, renewable chemicals, and carbon capture technologies for renewable fuels. The company operates ethanol production facilities and is expanding with new projects focused on renewable diesel and sustainable aviation fuel. Aemetis utilizes advanced technologies to convert agricultural and industrial feedstocks (such as orchard wood waste) into ethanol, other biofuels, and renewable chemicals like isobutanol.

AIRMADE™

Carbon-negative alcohols and fuels. AIRMADE™ is patented process that imitates photosynthesis. It uses renewable energy to convert excessive carbon dioxide into carbon-negative alcohols and fuels with only oxygen as a by product. Carbon dioxide is captured from industrial plants before they are emitted into the atmospher and is cooled, pressurized, and liquified. Hydrogen is produced with renewable energy through on-site electrolysis; an electrolyzer splits water into hydrogen, yielding oxygen gas a byproduct that is simply released into the air.

REFNOVA™ Biomass Fractionation

Fractionates a variety of lignocellulosic feedstocks to produce high-quality second-generation biofuels and biochemicals. REFNOVA is a process that generates the highest possible yield of biofuels and biochemicals from plant biomass. It uses plant residues that are left after the extraction of food or other primary products. Virtually all forms of plant biomass can be valorized with little or no waste through this process. The company increases income in local areas and minimizes environmental impact by applying REFNOVA at the source using discarded plant materials.

Updraft Gasification System

Gasification systems that convert non-recyclable organic waste (bark, sawdust, clean construction/demolition debris, biosolids from sewage sludge) into a product called "syngas" that can be used to fuel heat and power. This novel process has low air emissions and particulate carryover, reducing emissions controls and permits costs. The design is also very simple and has few moving parts. The gasification system can process many challenging renewable waste feedstocks with moisture contents ranging from 6-60% and sizes up to 75 mm.

Catalytic BioForming® Process

The Catalytic BioForming® Process converts aqueous carbohydrate solutions into mixtures of "drop-in" hydrocarbons. These hydrocarbon molecules are derived from renewable feedstocks but are equivalent to those found in petroleum products. These hydrocarbons are scalable because they maintain market acceptance; these molecules can be blended with existing infrastructure to produce premium-quality gasoline, diesel, or jet fuel. Fuels produced from these sustainable hydrocarbons are more energy efficient and have lower life-cycle carbon emissions than crude oil fuels.

Application of Genetically Modified Blue-green Algae in Bioethanol Production

Algenol develops blue-green algae (cyanobacteria) to produce ethanol and other fuels in an EPA-certified process. Blue-green algae transforms 80% of absorbed carbon into methanol, reducing the carbon footprint of ethanol and other fuel production. This process reduces costs, water usage, and reliance on crops as feedstock. The growing conditions of blue green-algae are also clean and controlled. Enhanced algae produces high quantities of biomass efficiently, making this process 15-20% time more efficient than producing corn-based ethanol. The overall process also produces minimal waste.

The Plantrose® Process

The Plantrose® Process is a water-based technology platform that converts plants into powerful ingredients. It converts water to a supercritical state to break down plants into foundational ingredients that can be used for various applications. The plants that are used in this process are sustainably grown and harvested. The ingredients from these broken down plants can be used in everyday consumer products and industrial applications. Using water instead of other chemicals also lowers costs.

UltraClean BlenD™

The Renewable Energy Group uses a genetically engineered microbial synthesis method to produce different diesel types from biomass, a more sustainable alternative to petroleum-based diesel. Their product is a proprietary fuel that combines renewable diesel and biodiesel. More specifically, their product combines EnDura Fuels™, VelociD™ and PuriD™. Their novel fuel provides excellent lubricity, high Cetane, and low Cloud Point for superior performance. This fuel also has much lower carbon intensity scores than petroleum diesel.
