Praxair’s Long Road to Capturing Carbon
by Debra Fiakas CFA In 2007, industrial gas supplier Praxair (PX: NYSE) teamed up with power plant equipment dealer Foster Wheeler (FSLT: Nadaq) to work on demonstration projects for cleaning up coal-fired electric generating plants. At first the duo planned to pursue clean coal technologies and oxygenated coal combustion systems. The joint press release at the time indicated Praxair’s “oxy-coal’ technology would be applied to Foster Wheeler’s ‘circulating fluidized-bed steam generators.’ The oxycombustion process is one of several proposed methods to capture carbon dioxide from coal-fired power plants. In a retrofit situation, pure oxygen would replace air...
Plasma Arcs For Pig Waste
This week MagneGas (MNGA: NASDAQ) announced new work completed toward plans to enter the commercial pork sector with a proprietary manure processing and disposal solution. Management held a meeting with the North Carolina Department of Environmental Quality and the U.S. Army Corps of Engineers to discuss MagneGas technology to treat agriculture waste and the state’s required environmental permit protocols. MagneGas aims to sell to pig farmers equipment based on its innovations.
The company wants to help pig farmers address environmental problems cause by manure accumulation with its proprietary waste sterilization process. Handling pig waste using conventional methods can be costly, but failure to...
Plastics from Carbon Dioxide
by Debra Fiakas CFA In the last post, I promised to close out this series on carbon dioxide capture with a note on a third example of Department of Energy funding for innovations in turning carbon dioxide (CO2) into a valuable raw material. Besides changing the chemistry of inorganic compounds and feedstock for biofuel production, CO2 has some potential for plastics. In 2010, the DOE placed a bet of $18.4 million on Novomer, Inc., which is a self-described sustainable chemicals developer. The bet appears to be paying off as Novomer and its partners go into production...
Chinese and EU Clash Over Airline Emissions
Doug Young China’s increasingly contentious trade relations with Europe suffered another setback late last week, when the EU threatened to fine Chinese airlines that were refusing to comply with a new controversial program to reduce greenhouse gases. China responded with its own threat by saying it won’t accept the EU’s planned carbon tax, raising the prospect of a dangerous new trade war. This latest in a recent series of trade conflicts between China and both Europe and the US is developing into a troublesome pattern that could spin out of control, endangering the nascent global economic...
Boiler Maker in Need of a Shot
by Debra Fiakas, CFA
A reserve split is in the works to keep shares of Babcock & Wilcox Enterprises(B&W) listed under the symbol BW on the NYSE. The stock price of this storied environmental engineering had slipped below the Exchange’s minimum price requirements. Ten shares will be melded into one beginning July 23, 2019.
Reverse merger math alone will not solve B&W’s problems. One hundred and fifty two years in business, B&W has been providing environmental technologies and services for energy and industrial customers since the company’s first boiler was sold right after the American Civil War. The company boasts that Thomas Edison was one of...
Three Water Recycling Stocks
by Debra Fiakas CFA The water series continues as we attempt to get arms around the very large market to package, deliver, purify, treat, and recycle water. As the need for water increases with population and economic activity, the use of waste waters has become an imperative. In this post we look at three companies helping to clean up, reclaim and otherwise recycle waste water. Ecosphere Technologies, Inc. (ESPH: PK) has introduced several water solutions that can be used in agriculture, mining, industry, or municipal applications. The company’s flagship Ozonix Technology is a chemical-free system to recycle...
Mantra’s Promise of Innovation
by Debra Fiakas CFA How often do we see the crowd rooting for the underdog? You could hear the cheers for Mantra Energy (MVTG: OTC) last week at the Marcum Microcap Conference in New York City. Mantra is a developmental stage company pursuing technologies to harness carbon dioxide for energy. Of course, the company has no revenue and therefore no earnings. Indeed, its technologies are so unique and as yet at such an early stage some might find them almost fanciful. Yet for some investors, a fanciful underdog is even better than another. Mantra sees itself...
OriginClear: Metals out of the Muck
After the worst of the wind and rain had died down from Hurricanes Harvey and Irma, and people began making their way back home, it became apparent that citizens of Texas and Florida would have more worries. The U.S. Environmental Protection Agency disclosed that at least thirteen toxic waste sites in Texas were flooded and damaged by Hurricane Harvey and another forty-one Superfund sites were negatively affected. Legacy contamination includes lead, arsenic, polychlorinated biphenyls, benzene and other carcinogenic compounds from historic industrial processes. After Hurricane Irma over six million gallons of wastewater reportedly flowed out to the coast and...

Earnings Roundup: Metals Prices Boost Covanta and Umicore
By Tom Konrad, Ph.D., CFA
You don’t have to own mining companies to benefit from rising metals prices.
This is a roundup of first quarter earnings notes shared with my Patreon supporters over the last week. Waste to energy operator Covanta and specialty metals recycler Umicore are both benefiting from skyrocketing metals prices.
Just as renewable energy and energy efficiency stocks have long shown that investors don’t have to own fossil fuel companies to benefit from rising prices of fossil fuels, recyclers like Covanta and Umicore are showing that you don’t have to own environmentally damaging mining companies to benefit from rising...
A Concrete Proposal
The Economist recently had a story on how the cement industry is beginning to confront the fact that the industry produces 5% of the world's emissions of greenhouse gasses. Carbon dioxide is emitted not only by the fossil fuels used to create the heat used in the creation of cement, and by the chemical reaction in that process. Unfortunately for us, cement is a remarkably useful building material, not least as a structural material which can also serve as thermal mass in passive solar buildings. All the large cement firms: Lafarge, Holcim, and Cemex (NYSE:CX) have joined a voluntary...
OriginClear Gambles on Marketing Program
by Debra Fiakas, CFA
Last week waste water treatment developer OriginClear (OCLN: OTC/QB) announced pilot projects for rental of its commercial water systems for pool cleaning. The company has several patents to its credit, protecting its innovations. OriginClear has developed a proprietary catalytic process to clean up solids from waste water as well as an oxidation technology to eliminate microtoxins in water. Unfortunately, the company has struggled to extract value from its efforts. OriginClear has yet to report profits. Indeed in the most recently reported fiscal year ending December 2019, revenue of $3.588 million only barely covered cost of goods of $3.217 million, let alone operating expenses that...
The Worst Waste
Jim Lane Peter Brown of FFA Fuels, promotes his company these days with the pithy slogan, “Fuels from the Worst Waste Around.” Which of course raises the legitimate question, what is the worst waste, and can we find a use for it? Discussions of worst waste will usually focus on the obvious say, landfill or the odious say, medical or nuclear waste. Toxicity and longevity are typical concerns, and that’s one of the reasons why nuclear energy remains controversial to this day. No Waste in Nature As LanzaTech’s Jennifer Holmgren observed in a recent article by...
Tetra Tech’s Two-Penny Disappointment
by Debra Fiakas, CFA
Tetra Tech’s (TTEK: NASDAQ) quarter earnings report last week was met with high drama as traders reacted with surprisingly vehement disappointment over the recent financial performance of the engineering and technology business. The company’s stock price gapped down in the first day of trading following the announcement, falling through a significant line of price support. The shares continued to fall and finished the week at a price not seen since mid-April 2017 before the stock began its recent drive higher.
The drama unfolded after Tetra Tech reported net earnings of $0.52 per share on $498 million in total...
Tetra Tech: Energy Engineer
by Debra Fiakas CFA In the coming years power generators will be under pressure to meet new standards for lower carbon emissions embedded in the EPA’s Clean Power Plan. Each state has to meet a set of standards set by the EPA based that state’s particular circumstances in electrical generation. The carbon pollution limits begin in 2022 and ramp to full effect by 2030. Power generators could meet standards by reducing harmful emissions from existing fossil fuel-fire plants. Unfortunately, that may prove too costly at some of the older plants. It is logical that power generators...
The Low Cow-bon e-Cow-nomy
Jim Lane This month in Finland, a team of intrepid researchers herded one thousand European cows one-by-one into a glass “metabolic chamber” to measure their methane emissions, digestion, production characteristics, energy-efficiency, metabolism, and the microbial make-up of their rumens. The Project is known as RuminOmics, but if it had been titled The Truman Show II: When the Cows Come Home, we wouldn’t have been a bit surprised. The Cow Emission Crisis. No Kidding Around. The ultimate aim of the study was to find an optimal, low-emission, high-yield cow, and the team noted in its premise that of all greenhouse...
