Renewable

Carbon recycling technology. This technology uses bacteria to convert waste gas (pollution) to fuels and chemicals. Carbon gas streams are common byproducts of established processes. LanzaTech utilizes these gas streams to produce fuels such as ethanol and chemicals such as 2,3-butanediol at high selectivities and yields. LanzaTech's microbes can also consume H2-free CO-only gas streams due to a biological water-gas shift reaction with CO2 and CO catalyzed by carbon monoxide dehydrogenase.

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.

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.

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.

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.

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.
