The ACS Green Chemistry Institute will be hosting a business plan competition on June 18, 2014 at the 18th Annual Green Chemistry and Engineering Conference, which will be held outside of Washington D.C.
The competition is for early stage ideas – but not ideas for renewable energy production or biofuels (there are no shortage of competitions for those). If you have an idea for a green innovation that only chemists would truly understand, this is your chance.
The first deadline to be aware of is April 25 – that’s when to submit your 10-15 slide PowerPoint presentation and optional YouTube video. Just aim to be done by Earth Day and you’ll be right on schedule.
The competition website includes a host of great links to advice on how to communicate and advance your start-up idea. And don’t forget to review (memorize them!) the 12 Principles of Green Chemistry.
When you think of a typical “green” cleaner or bio-based surfactant, an image of mild, citrus-scented liquid dish soap might come to mind.
But you wouldn’t use that stuff to clean a year’s worth of burnt grease from your oven or wash the latex paint off your paint brushes. Usually, those kind of tasks call for cleaners that require significant ventilation.
But thanks to a collaboration between Stepan, a cleaning products ingredient maker, and Elevance, a biobased specialty chemical firm, consumers and professionals will be able to aggressively clean things without seeing stars.
Elevance and Stepan are talking about their first commercial product launched out of the collaboration called Steposol MET-10U. The firms say it can take the place of high pH alkaline degreasers in household cleaners, N-methyl pyrrolidone in adhesive removers, and methylene chloride in paint removers.
The product has a biorenewable carbon index of 75%. It is low VOC, with a boiling point of 297C, and can be used in much lower concentrations than the the solvents it replaces.
How is this done? Basically, Elevance uses olefin metathesis to create specialty building block molecules from waste oils (i.e. from oil palm farming). And those molecules can be very specifically functionalized for different uses, i.e. to create esters for surfactants, lubricants, and personal care products.
Of all the benefits of Steposol, it’s low volatility really makes it a winner, according to Andy Corr, Senior Vice President at Elevance. California has issued strict VOC regulations for many consumer products – for both human health and air quality reasons. Andy points out that even biobased ingredients, such as d-limonene made from citrus peels, can be very volatile.
And Robert Slone, VP of surfactant product development at Stepan, says this is only the first of many outcomes from the partnership, which formed back in 2010. “It is exciting to see the performance that we are able to achieve – chemistry that is much more environmentally responsible, less toxic, non-corrosive, and low VOC than the options that are out there currently.”
Technologies for – and commercialization of – materials and chemicals made from a variety of biobased feedstocks “have reached an inflection point” and are poised to grow significantly over the next four years, according to the minds over at Lux Research.
Research analyst Julia Allen says overall capacity will nearly double, reaching 13.2 metric tons in 2017. Growth rates by segment vary but all are robust, spanning intermediate and specialty chemicals and polymers. The biggest percentage growth, and largest category of production, will be for intermediates like adipic acid and that old fashioned biobased product, lactic acid.
The only fly in the punch mentioned in the press release (full report available to Lux clients) is that cellulosic feedstocks are likely to continue to grow slowly. Corn starch and sugar cane will still dominate, and oily bio feestocks and waste gas will also play a role.
Here’s a nice example of the biobased industry’s maturation. One of the larger biobased chemical intermediate companies is Myriant, a producer of succinic acid made from sugar. Today the company said it has supplied commercial quantities to downstream customer Oxea for use in production of pthalate-free plasticizers. Oxea is a large-ish intermediates company owned by Oman Oil Company. Applications for the plasticizer include food cling wraps, flooring, soft toys and adhesives & sealants.
Of course, just because the industry as a whole is on surer footing and poised for growth, does not mean the same is true for individual companies. In fact, once the market is in a position to determine demand and pricing, we may see what business reporters politely call “consolidation.”
For instance, Florida-based biobased specialty chemical company LS9 was recently bought by mainstream biodiesel fuel maker Renewable Energy Group for a not-huge price tag. And biobased plastics supplier Cereplast has filed for Chapter 11 bankruptcy just this week.
Where I live, I have to pay for each bag of household waste picked up by the trash man. Each bag gets a sticker, and every so often I purchase a sheet of stickers for a not inconsiderable amount of money.
Luckily, I recycle and compost, and so my actual trash output is minimal.
Still, whatever volume of garbage I produce is a liability on the household balance sheet. Meanwhile, in the biobased/renewables economy, any source of unused carbon can be an asset if handled properly. And so I’m a bit surprised that I did not take note of one important cleantech project that came online in 2013: Abengoa‘s municipal solid waste-to-ethanol plant in Salamanca, Spain.
Thanks go to Jim Lane from Biofuels Digest for describing the facility in his Bioeconomy Achievement Awards post. In my defense, I have heard of and followed the other projects that made his list.
The biofuel facility was inaugurated in June – and judging from the press release I imagine that Abengoa workers are busy adjusting it and scaling it up. It has an eventual capacity to take in 25,000 tons of municipal solid waste and produce about 400,000 gal of ethanol per year. That is a great deal of ethanol – much closer in output to a Midwestern corn ethanol plant than any advanced biofuel plant I’ve come across.
The secondary benefit of course, besides fuel, is that the amount of waste is reduced by 80%, with only the remainder going to a landfill.
In addition to scale, the other striking feature of the plant is that it uses a fermentation and enzymatic hydrolysis process to get at the carbon inside the cellulose and hemicellulose fraction of waste. Other waste to fuels plants (like Enerkem’s in Alberta) use more physical/chemical processes such as gasification or pyrolysis and inorganic catalysts.
Generally the stated benefits of the thermo-chemical routes are that all carbon-based inputs (i.e., old tires, plastics – you name it) are converted. But whether this distinction is important is questionable. For example, even gasification projects require upfront sorting and shredding of trash.
Perhaps someday when I put out my trash, rather than paying for the privilege, I’ll get paid instead.
This has been a big season for biobased chemicals firm Genomatica. In late November, BASF announced that it used the company’s engineered microbe fermentation technology to scale up renewable production of 1,4 butanediol (BDO). And earlier this week, Genomatica announced a new partnership with Brazil’s Braskem to begin manufacture of biobased butadiene, starting with a pilot plant.
“We’re tremendously excited,” said Genomatica CEO Christophe Schilling yesterday, in a chat with Cleantech Chemistry. “We’re positioning ourselves to get to this point – for many years we’ve viewed ourselves as the partner for the chemical industry when it comes to using biotechnology as a way to make chemicals. Not just for BDO or butadiene but for a broad range of chemicals.”
But we at the blog have noticed that these days, news like this just does not meet the same level of excitement that it would have back in say, 2010.
“It really reflects the state of cleantech now – people are struggling with ‘where did all the enthusiasm and energy go?’” says Mark Bunger, an analyst at Lux Research. “It is a natural part of how technology evolves. Initially there is a lot of hype, then you see a trough of disillusionment, followed by a plateau of interest.”
Bunger says all technologies tend to follow this pattern first identified by IT consultancy Gartner. It is called the hype cycle. Certainly, the last two years have been trough-like in the excitement level. After a certain number of years pass, when a company does prove that its technology works, it may be met with a bit of a shrug.
To get out of the trough of disillusionment, according to the Gartner theory, requires surviving a shakeout where some technologies don’t prove themselves. Investments continue if the surviving firms show that early adopters are satisfied with the technology’s results. The two Genomatica news items show that the firm has likely passed this barrier.
To then climb the slope of enlightenment and get out of the trough, Genomatica will have to show more than one instance of the technology benefiting a large enterprise and commercialize second- and third-generation products. This is where Genomatica is heading with its partners.
The goal, in the end, is for mainstream adoption to take off (the Plateau of Productivity). Genomatica, and other producers of C4 chemicals, says that the shale gas boom will provide a timely market pull for their technologies. The reason? Petrochemical plants that use “light feedstocks” such as natural gas produce a much smaller ratio of C4 chemicals than facilities that use crude oil. We’ll find out in the next few years whether the tail-end of the biobased chemicals hype cycle will fit nicely with the peak of the shale gas hype cycle.
Microbes! They are tiny but powerful. And big companies are buying in – according to a wave of announcements that began late last week. Here are some highlights from my inbox.
Amyris, which has long been talking about making biofuels – particularly diesel and jet fuel – from its biobased farnesene, will embark on a joint venture with French fuel company Total. Recently Amryis had pulled back from its fuel ambitions, but now it will move ahead with this 50/50 venture. Total is already an investor in Amyris and owns 18% of the firm’s commons stock. Where’s the microbe? Amyris uses engineered microbes to make farnesene from sugar.
Meanwhile, Monsanto and Novozymes will combine forces to develop and market biological crop products based on microbes. The deal includes a $300 million payment from Monsanto for access to Novozyme’s technology, which the firm has been building for the last seven years. Microbes have long been used as inoculates for nitrogen-fixing legume plants but in the last few years microbial products have been developed to help with phosophate uptake, to fight fungus and insects, and promote plant vigor and yield. Interestingly, Ag giant Monsanto only last year introduced a microbial platform. This deal sounds like a way to catch up.
Some microbes can ferment gases and make desirable chemical intermediates. LanzaTech has been an innovator in this space so we’ll start with that company’s new deal with Evonik. The firms have a three-year research agreement to develop a route to biobased ingredients for specialty plastics. The feedstock will be synthesis gas (syngas) derived from waste. LanzaTech has already begun production at an earlier joint venture that produces ethanol from the industrial waste gases of a large steel mill in China.
Invista is probably best known for its synthetic fibers business (think Lycra and Coolmax) but it also has a chemical intermediates business. And it now has a deal with the UK Center for Process Innovation to develop gas fermentation technologies for the production of industrial chemicals such as butadiene. The two are eying waste gas from industry as a feedstock. Rather than spin the work as a sustainability play, Invista says it may significantly improve the cost and availability of several chemicals and raw materials that are used to produce its products.
Cleantech Chemistry thanks C&EN colleague Marc Reisch for contributing this news about biobased chemicals.
M&G Chemicals, a unit of Italy’s Gruppo Mossi & Ghisolfi, plans to build a $500 million biorefinery in China to make ethanol and the polyester raw material mono-ethylene glycol from 1 million metric tons of biomass per year. The facility in Fuyang, Anhui Province, China, will be four times larger than M&G’s recently commissioned Crescentino, Italy-based biorefinery when it is open in 2015.
To be built in a joint venture with minority partner Guozhen Group, a Chinese energy and real estate conglomerate, the Fuyang refinery will use Proesa technology from Beta Renewables, a joint venture partly owned by M&G which is also a polyethylene terephthalate maker.
M&G’s CEO Marco Ghisolfi says the Fuyang refinery “is the first act of a green revolution that M&G Chemicals is bringing to the polyester chain to provide environmental sustainability.” The company’s entry into China will ultimately position it to supply PET to firms such as beverage maker Coca-Cola which have advanced the development of renewably-sourced bottles, among them Coke’s own “PlantBottle.”
Coke currently buys ethanol-based ethylene glycol from India Glycols to make a PET bottle that is nearly 30% biomass derived. To increase feedstock availability, last year Coke formed a partnership with India’s JBF Industries to build a 500,000 metric-ton-per-year bio-ethylene glycol plant in Brazil, also set to open in 2015.
While the JBF plant will use sugarcane and sugarcane-processing waste as feedstock, M&G’s China facility will be based on wheat straw and corn stover. So M&G’s plant has the added virtue of depending on a non-food feedstock source.
But the ethics of using one feedstock crop versus another, or of using biomass versus petrochemical feedstocks, might not matter if consumers don’t care. At the BioPlastek Forum, a conference held in June, Coke, Ford Motor, and yogurt makers Danone and Stonyfield Farm told bioplastic makers that most consumers are unwilling to pay higher costs for bioplastics (C&EN, July 15, page 18).
And while the large M&G and JBF plant may have the economies of scale to drive down bio-based PET costs, they’ll encounter headwinds from petrochemical-based ethylene glycol makers. Lux Research senior analyst Andrew Soare points to the spate of ethylene and derivatives plants planned in the U.S. based on low-cost natural gas. M&G itself, for instance, is building a 1 million metric-ton-per-year PET polymer plant in Corpus Christi, Texas.
However, M&G will be challenged to make cost competitive ethylene glycol in China given the competition expected from U.S. petrochemical producers, Soare says.
Imagine a giant pile of biomass – lets say wood chips for simplicity sake. And next to the wood chips is a big pile of money (likely from investors, whose patience for payback may vary). In a third pile is a group of job candidates: engineers, chemists & microbiologists.
To get useful energy from the first pile of feedstocks requires careful consideration of all your piles. The wood chips can be burned, fermented, or – bear with me now – squeezed. Each approach requires different amounts of feedstock, cash up front, and expertise to get a particular type and amount of fuel or energy.
C&EN’s own Craig Bettenhausen has taken a look at the benefits – and potential downsides – of squeezing the wood chips to make liquid fuels, specifically hydrocarbons that can be made into drop-in biofuels (the best kind!). Of course he doesn’t say “squeezing” – experts call it pyrolysis. Bettenhausen explains that the biomass is subjected to high temperature and pressure in an oxygen-free environment (imagining this is making me feel a little breathless and claustrophobic). Check out the free story to learn what happens next.
Meanwhile a press release from our friends at Battelle in Columbus, Ohio, nicely illustrates one way pyrolysis might pull ahead of other technologies (i.e., fermentation into ethanol or gasification into syngas). A group of Battelle engineers and scientists have built a mobile factory that can travel to the site of your big pile of wood chips and convert it into up to 130 gal of oily hydrocarbons per ton of chips per day. The little factory is installed on the flatbed trailer of an 18 wheeler.
“This feature makes it ideal to access the woody biomass that is often left stranded in agricultural regions, far away from industrial facilities,” the press release notes. “It’s potentially a significant cost advantage over competing processes represented by large facilities that require shipment of the biomass from its home site.”
Still, as Bettenhausen explains, pyrolysis – as it is being scaled up today – has not yet proven itself at scale or made profits for anyone. Stay tuned.
It sounds like something from a greenskeeper’s nightmare – certain folks have plans to grow algae and dandelions on purpose, and in large quantities.
Firstly, in the golf course-choked state of Florida, Algenol CEO Paul Woods is scouting a location for a $500 million algae-to-fuels plant. The company was founded and has been operating in the southern part of the state for years now. Its claim to fame is cheap ethanol made from cyanobacteria in a custom-designed bioreactor. Woods does not, as far as I know, have plans to re-purpose stagnant water traps for the purpose of growing his feedstock.
But Florida, though it is sunny and warm, might have missed out on this slimy opportunity. In recent months, Woods questioned the state’s commitment to biofuels. For example, Governor Rick Scott repealed a state law requiring 10% ethanol in gasoline. But now, according to Fort Myers ABC 7 News, the company has been persuaded to build in its home state – apparently the estimated 1,000 jobs was just the ticket to getting a warmer welcome. Algenol needs to be sited near a major CO2 source (i.e., factory or power plant emissions) and says potential partners have come forward.
Meanwhile, it’s called the Russian Dandelion, though it grows in Germany. This common lawn scourge is bringing about not curses, but praise, for its rubber producing capability. Tire makers are enthused about its white latex sap. The goo is expected to give the subtropical rubber tree a bit of competition. Making rubber from dandelions is not a new idea, but has been given new life by a project at the Fraunhofer Institute for Molecular Biology and Applied Ecology.
Fraunhofer scientists, in a collaboration with folks from tire firm Continental are working on a production process for making tires from the dandelions. In addition to the manufacturing process, the researchers are also using DNA markers to grow new varieties of the plant with higher rubber yields.
The project sounds kind of cute but the researchers behind it are dead serious. The partners have already begun a pilot project and plans are afoot to move to industrial scale. According to them, the first prototype tires made from dandelion rubber will be tested on public roads over the next few years.
You can read an earlier post on the history of dandelion rubber here.
Bill Gates (yes, that Bill Gates), through a fund called Gates Ventures, is investing $15 million in advanced biofuels firm KiOR. Gates is not a huge cleantech investor generally (though he has backed other firms such as the young MIT spin-off Liquid Metal Battery). So it’s rather interesting that he’s decided to invest in KiOR, which is not at all an “early stage” tech firm – in fact, it is a public company.
Vinod Khosla, a tech pioneer who is much more well known as a cleantech investor with deep pockets, has committed to putting in another $85 million to KiOR in debt and stock. Khosla was instrumental in the founding of the company and has been an unusually loyal and generous benefactor.
With this $100 million infusion, KiOR says it will be able to build out its capacity-doubling project at its Columbus, Miss. facility (see Khosla, Kior Double Down).
If we go back in time a bit to the end of the second quarter, we see that KiOR had started shipping its drop-in fuels (gasoline, diesel, heating oil) made from wood. But the amount of production was behind schedule, and its cash position was delicate, to say the least. At the time, analysts suggested that the firm should bring in a corporate partner such as a refining company. But that’s not what happened.
It is clearly good news for KiOR that it has a few friends who are willing to keep dipping in to their own pockets to make sure its first facility can reach the point where it generates enough cash to fund operations – and presumably prove out that KiOR’s next commercial facility (planned for Natchez, Miss.) will be profitable.
And its only fair to note that the same analysts who suggested KiOR get an additional large investor are also very bullish on the company. So what is there to like about KiOR?
- KiOR has significantly increased uptime at the Columbus facility
- It has produced and shipped actual product
- Yields are rising
- Drop-in biofuel is considered a much more desirable product than ethanol
- KiOR’s technology can accommodate cheap feedstocks (the expansion will use waste railroad ties)
The main negative, in fact, was the near-term need for additional capital. And even back in August – before both recent investment announcements – analysts at Credit Suisse and Raymond James had an outperform rating on KiOR’s stock.
Does all of this mean that KiOR is a guaranteed win? No, of course not. But I find it interesting how far KiOR is poised to go with the help of a few true believers.
Elevance comes to the U.S.
Elevance is another cleantech firm that is expanding its commercial operations. The company makes specialty chemical intermediates – functionalized esters and the like – for use in downstream products for personal care, coatings, lubricants and additives. Its feedstock is vegetable oil, which it processes using olefin metathesis.
The company did not have an IPO, as KiOR did, but chose instead to raise private capital. Its first plant, in Gresik, Indonesia is a large one, at 180,000 metric tons per year. Elevance says that its output there is all spoken for, and it is now proceeding with plans to build a second plant, also in Natchez, Miss. That facility is expected to come online in 2016.
