The world\u2019s largest conference on “CO2<\/sub> as Feedstock for Chemistry and Polymers\u201d (Haus der Technik Essen, 10-11 October 2012) covers an incredibly wide range of uses for CO2, developing a vision for a sustainable carbon dioxide economy.<\/b><\/p>\n

Carbon dioxide (CO2<\/sub>) emissions, the end product of burning fossil fuels or biomass, are largely responsible for the greenhouse effect and thus for climate change. A reduction in CO2<\/sub> emissions is therefore at the very top of the international political agenda. Trials are running in parallel to explore underground sequestration of CO2<\/sub> from power stations, thereby removing it from the atmosphere.<\/p>\n

It would at first sight seem paradoxical to wish to use energy-poor, inert CO2<\/sub> molecules. Considerable research and development efforts in recent years have led to new and innovative CO2<\/sub>-recycling technologies and a vision of a CO2<\/sub> economy. CO2<\/sub> recycling has quickly become a hot topic for the future for every large company in the chemicals and plastics sector. Wirtschaftswoche reports that even Novel prizewinners George Olah and Joseph Stiglitz have recognized the gas as a future fuel and raw material of the chemical industry.<\/p>\n

In the last three years, the US Department of Energy and the German Ministry for Research (BMBF) have each provided some \u20ac100 million for research into new uses for CO2<\/sub>. These investments are already bearing fruit. Evonik, BASF and Bayer Material Science are working hard on CO2<\/sub> polymers. Siemens and BASF demonstrated the first applications in household appliances such as fridge compartments and vacuum cleaner casings at the ACHEMA fair in Frankfurt in June 2012. The automobile and aircraft industries are working on fuels that depend on neither from oil nor biomass, but are instead derived from solar and wind power \u2013 and CO2<\/sub>. These are also early days for a new chemical sector: recycling \u2013 the cascade use of CO2<\/sub> as a raw material for the chemical industry. Now new chemical and electrochemical reactions must be discovered and further technologies developed (e.g. the efficient separation and purification of CO2<\/sub> from the emission flow) to turn the climate killer into a renewable resource.
\nAlessandra Quadrelli from Lyons University sees CO2<\/sub> as one of the most important raw materials for the chemical industry in the future. According to her calculations, innovative chemical uses of CO2<\/sub> could achieve up to 10% of the global reduction in greenhouse gases that is required.<\/p>\n

CO2<\/sub> polymers \u2013 new options for the plastic industry<\/b>
\nThe main new CO2<\/sub> polymer is polypropylene carbonate (PPC), which was first developed 40 years ago by Inoue, but is only now coming into its own. PPC is 43% CO2<\/sub> by mass, biodegradable, shows high temperature stability, high elasticity and transparency, and a memory effect. These characteristics open up a wide range of applications for PPC, including countless uses as packing film and foams, dispersions and softeners for brittle plastics. The North American companies Novomer and Empower Materials, the Norwegian firm Norner and SK Innovation from South Korea are some of those working to develop and produce PPC.
\nBayer Material Science exhibited polyurethane blocks at ACHEMA, which were made from CO2<\/sub> polyols. CO2<\/sub> replaces some of the mineral oil use. Industrial manufacturing of foams for mattresses and insulating materials for fridges and buildings is due to start in 2015.<\/p>\n

PPC as a softener for bioplastics<\/b>
\nMany bio-based plastics, e.g. PLA and PHA, are originally too brittle and can therefore only be used in conjunction with additives for many uses. Now a new option is available. They can cover an extended range of material characteristics through combinations of PPC with PLA or PHA. This keeps the material biodegradable and translucent, and it can be processed without any trouble using normal machinery. The vacuum cleaner casings that Bosch Siemens Household Appliances (BSH) displayed at ACHEMA are predominantly made of BASF\u2019s PPC and PHA and are intended as a substitute for the bulk plastic ABS. The first internal life-cycle analysis studies demonstrate the material\u2019s clear advantages. PPC\/PLA combinations were used in fridge compartments.<\/p>\n

Fuel from wind power, solar power and CO2<\/sub><\/b>
\nAn outside energy source is required if CO2<\/sub> is to be used as fuel. The major option here is to use surplus wind and solar power, which frequently occurs in Germany. Storage is a central concern with the expansion of renewable energy.
\nIf the surplus electricity is used to produce hydrogen (H2<\/sub>) from water, this can then be converted into various fuels in conjunction with CO2<\/sub>. The first reaction is that of H2<\/sub> with CO2<\/sub> to form methane (CH4), which can then fed into the gas network. Further chemical processes lead to methanol, petrol, diesel and kerosene. The high temperature steam electrolysis that is being optimized in the BMBF project now achieves a 70% efficiency level (electricity to hydrogen).
\nIn 2011 a consortium of businesses in Iceland began building the first commercial plant, which will produce 5 million litres of methanol per year from CO2<\/sub>. That would cover 2.5% of Iceland\u2019s fuel needs.<\/p>\n

CO2<\/sub> as growth substrate for algae and bacteria<\/b>
\nHowever, the world\u2019s largest use of CO2<\/sub> takes every day right in front of our eyes. With the help of photosynthesis (and with the action of sunlight), plants convert carbon dioxide into sugar, which they then use to produce all the important bio-molecules. This can also be commercially exploited: in large-scale reactors algae are gassed with carbon dioxide from power stations and then produce biomass.
\nSome bacteria can also use CO2<\/sub>. The metabolism of these so-called acetogenic bacteria enables them to use CO2<\/sub> along with a carbon monoxide\/hydrogen mixture (synthesis gas) as a growth substrate and as a basis for producing various products such as acetone, butanol and ethanol. A joint project between RWE and biotech company Brain was able to isolate numerous strains of bacteria in power station chimneys that could serve this purpose.
\nChanges through molecular engineering to the bacteria can also lead to products other than the normal end products – for example the acrylic acids needed to produce PMMA (a polymer better known as plexiglass) and the biopolymer PHB. Synthetic biology methods should even allow for the production of customized bacteria in future for optimal CO2<\/sub> efficiency. Evonik in particular is working on the production of various chemicals, while the New Zealand firm LanzaTech is developing aircraft fuel and specialty chemicals based on butanol derived from CO2<\/sub> fermentation.<\/p>\n

The world\u2019s largest conference on CO2<\/sub> as feedstock to be held in Germany<\/b>
\nOn 10 and 11 October 2012 nova-Institute will be organizing an English-language “Conference on Carbon Dioxide as Feedstock for Chemistry and Polymers\u201d at the Haus der Technik in Essen with an accompanying exhibition. There will be comprehensive presentations and discussion of every facet of the new uses of CO2<\/sub> .
