Rio Valley Biofuels, New Mexico's first and one of the Southwest's only commercial producers is located in Anthony, New Mexico. We began commercially producing biodiesel in July of 2006 using recycled oil from local food processors. Our feedstocks include a large variety of lipid oil sources including used vegetable oil, crude cottonseed, tallow, sunflower, canola, soy, palm, and a number of others. Our continuing goal is to provide affordable biodiesel to businesses and farmers in our local community here in southern New Mexico. We believe that selling locally produced fuel will help businesses in the community who would like to use renewable fuel, but cannot afford the freight costs associated with bringing fuel from as far away as the Midwest. All biodiesel produced at our facility is produced to ASTM D6751 specifications. Our quality control program consists of extensive documentation of each batch produced along with testing at an independent certified lab. Rio Valley Biofuels is a member of the National Biodiesel Board and our facility is registered with the IRS, the EPA, and New Mexico.

In 2017, 840 million people had no electricity access. Due to population growth in under-served countries, hundreds of millions more will require an electricity connection by 2030. For many rural communities, expanding the national grid is not the answer. The cost of grid expansion is high, particularly if distances are large and terrain challenging. Kinetic Hydro Ltd have developed an innovative river turbine to generate electricity from the largely untapped energy resource available in the flow of water in the world’s rivers. This includes considerable potential in Sub Saharan Africa and in South and East Asia where the energy access requirements are most pressing. Our river turbines can produce continuous (baseload) power, contributing to the energy security of rural communities. They are designed to suit the practicalities of remote areas, including easy transportation, installation and maintenance; features that are essential to making power accessible to those who would otherwise be left behind.

SOLATOM es una empresa tecnológica que desarrolla sistemas solares para generar calor de alta temperatura en procesos industriales como la fermentación, pasteurización, secado, tintado, cocinado, escaldado, etc. Qué problema solucionamos: Actualmente 2/3 del consumo energético en la industria es calor, el cual se produce utilizando combustibles fósiles (caros y contaminantes). En el caso de industrias intensivas en energía, como la de alimentación, el consumo de energía térmica puede llegar a representar el 30% de sus costes de producción, mermando sus márgenes y competitividad. España es el país Europeo con mayor radiación solar, pero las tecnologías solares actuales sólo son competitivas a gran escala (Grandes plantas solares), haciéndolas inviables en aplicaciones industriales. La solución SOLATOM: Solatom ofrece a las industrias una alternativa viable a los proyectos solares tradicionales produciendo módulos solares pre-ensamblados, que al unirse forman la planta solar. Estos módulos son transportables, por lo que pueden ser construidos totalmente en fábrica en lugar de construirse in-situ como en los diseños tradicionales. Este nuevo enfoque tiene la ventaja de poder fabricar en línea de montaje, lo que reduce los costes de producción en un 63%. Esto hace posible que finalmente las industrias, dispongan de un sistema capaz de generar energía térmica un 37% más barata que la que generarían con sus sistemas convencionales basados en energía fósil.

Quatt is an ambitious start-up that was founded in 2021 by two entrepreneurs and brothers from the Netherlands. Our goal is to accelerate the transition to sustainable heating in the Netherlands and abroad. Our first product is a smart, hybrid heat pump for the Dutch market. The Dutch government is strongly incentivizing 8 million homeowners to get rid of natural gas and start heating sustainably within the next few decades. Unfortunately, the current pace of heat pump installations is far too low. Therefore, Quatt is improving the overall customer experience, adding smart control software, simplifying the installation job and, last but not least, greatly enhancing the aesthetics. By doing so, we want to increase adoption by an order of magnitude. We are developing a highly advanced control system based on several AI technologies, like Machine learning and Deep learning. This system enables us to operate our heat pumps, in conjunction with already installed natural gas heaters, in the most cost- or energy-efficient way, at any given day. We estimate this can reduce heating costs by about 20%. By combining this with D2C sales & installation, Quatt is aiming to reach a payback time of 3-4 years; and thus a very quick uplift in sales. Quatt is working towards an installed base of 1 million heat pumps.

Frequently asked questions

Updated 23 October 2026

What is Enterprise League?

Enterprise League is a free business directory that helps buyers find the right company by sector and country. Every company has a profile showing what it does, what it offers and how to get in touch.

Is it free to list my company?

Yes, and it stays free: no card, no paid tier. Your profile appears in search results and category pages, can show up to 20 products and services, and lets buyers message you or ask for a quote.

How does verification work, and what does it cost?

Verifying your company is free. Confirm a code we email to an address at your company’s website, or send a company registration document for our team to check, and the verified badge appears on your profile. To show the badge in the directory and search results as well, take out a subscription: the first 14 days are free, and the price is on our pricing page.

Where does the company information come from?

Most profiles are built from public sources, such as official company registers. Claim your company’s profile to correct its details and add your own.

How do I claim or correct my company’s profile?

Open your company’s profile and choose Claim Profile. If you use an email address at your company’s website, a 6-digit code makes the profile yours at once; otherwise our team reviews your request, usually within a few days. Spotted a mistake on a company that isn’t yours? Tell us through our contact page.
