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...
China Everbright Greentech
by Debra Fiakas CFA Investors based in the U.S. need to look far and wide for new stock issues from renewable energy companies. Capital markets activity has slowed in the last couple of years, in part to due to their own success. In reaching new efficiency in energy production, renewable energy companies are generating their own internal capital and are not as dependent upon the capital markets. The Hong Kong market has come to the rescue of U.S. investors with a ‘green’ offering China Everbright Greentech Ltd. is now trading on the Hong Kong Exchange with the...
Bion: Waste To Dollars
Earlier this week Bion Environmental Technologies (BNET) received approval of a patent for its proprietary ammonia recovery process. Bion’s technology converts livestock wastes into ammonium bicarbonate. Patent protection in the U.S. paves the way for Bion to deliver an environmentally friendly chemical to the market at attractive profit margins.
Ammonium bicarbonate is used for a variety of purposes from leavening to crop additives. It is the fertilizer market that has caught Bion’s attention. The company intends to ‘close the loop’ for the agricultural sector by helping livestock producers economically dispose of waste and then delivering a fertilizer for food crops that qualifies as organic.
It is an attractive...
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...
Greenhouse Gas Management Stocks: Key To A Real Climate Change Portfolio?
There has been a lot written lately about how to turn climate change into an investment opportunity, including on this site. Not all of it is, however, especially useful or relevant. In the worst cases, commentators have ascribed the 'climate change investment opportunity' label to just about any industry out there, indiscriminate of whether or not there really is a strong and direct connection. If you are seriously interested in playing the climate story, you should stay focused on near and medium term opportunities with real and tangible links to what is currently going on with the climate...
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...
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...
Carbon Capture and Storage: By the Numbers
"We have over 200 years of coal reserves, and we have to/will use them." I have heard some variation of this line far too many times, and I have little patience for it. Here's why: We don't have over 200 years of reserves. The real number for economically accessible coal is less than half that. A square, 100 miles on a side in the Southwestern deserts of the US could meet the electricity needs of the entire nation, if solar energy were converted to electricity at 10% efficiency. There's a lot of desert in the Southwest, and we're...
Southern Company’s Carbon Capture Testing
by Debra Fiakas CFA Coal emissions photo via BigStock An electric utility of Southern Company’s size - $38.3 billion in market capitalization - is not among the typical company covered in the Small Cap Strategist weblog. Southern (SO: NYSE) owns and operates six dozen power plants in the southeastern U.S., generating 12,222 megawatts of power from a mix of fossil fuel, hydroelectric, nuclear and solar plant assets. The company earned $2.68 in earnings per share on $16.5 billion in total electric power sales. Sales dipped in 2012...
OriginOil Renames Product – Will It Help The Business?
by Debra Fiakas CFA Mid-March 2014, OriginOil, Inc. (OOIL: OTC/QB) relaunched its waste water treatment process for shale gas producers. The company’s CLEAN-FRAC and CLEAN-FRAC PRIME products are now called OriginClear Petro. OriginOil is expanding into the industrial and agricultural waste water treatment markets using the product name OriginClear Waste. The company has been toiling away since 2007 perfecting its “Electro Water Separation” process that uses electrical impulses in a series of steps to disinfect and separate organic contaminants in waste water. In June 2014, OriginOil management declared its development stage completed and start of full...
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...
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...
BioNitrogen: Valuable Technology, Management Questions
by Debra Fiakas CFA My last post outlined how Bion Environmental Technologies, Inc. (BNET: OTC/QB) is transforming livestock waste into organic fertilizer. Bion is not the only aspiring fertilizer producer. BioNitrogen Holdings Corp. (BION: OTC/PK) was recently patent protection for a process to produce urea from stranded natural gas. Instead of burning off the unwanted gases, oil and gas operators can turn it into an economically viable by-product. There is more than just cash flow at stake for oil and gas producers. Burning off stranded gas increases harmful emission that can lead to penalties in the...
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...
Water Out Of Thin Air
It is an irony that surrounded by the flood waters of Hurricanes Harvey and Irma, a drink of fresh, clean water may be hard to come by. Of course, the all three levels of government make plans for stockpiling and deploying emergency bottled water well ahead of natural disasters. Yet in the hours and days following the worst of both the recent storms, the media was filled with stories of people who lacked water.
What if water could be made manufactured? If such a technology existed, what a boon it might be to thirsty storm victims.
Ambient Water Corporation (AWGI: OTC/PK) has...
