Definitions are tricky. They tend to change with the times depending on perspective and technology. Take the biorefinery for example. At the simplest level (Figure 1) a biorefinery converts biomass feedstock into a variety of products by means of a reactor.<\/p>\n
Most of us would probably agree that facility that converts cornstarch to ethanol is a biorefinery. Likewise, feeding wood chips into a gasifier to produce syngas and heat would also fall within the bounds of the biorefinery definition. Or even the production of succinic acid by fermentation.<\/p>\n
What about other types of biorefineries? A campfire converts wood into heat, gases and char using a thermochemical reaction. A compost pile converts assorted biomass into heat, gasses and fertilizer via microbial action. A cow converts grass into meat, methane, milk and manure through an integrated process.<\/p>\n
Where is this going? The point is that biorefineries are on a trajectory that will challenge and expand our thinking of what they are, what they do and how they do it. This is important in how businesses and investors approach the next wave of building and financing biorefineries.
\nDrivers of Change<\/p>\n
Drivers of change in manufacturing can be thought of as the interface between need, opportunity and technology (Figure 2).<\/p>\n
Need as a driver can come from environmental regulation, demand of growing populations, social pressure and a variety of other factors. These drivers, combined with opportunity and technology often create an environment for innovation and are a major factor in getting a project funded.<\/p>\n
Opportunity, such as the availability of a new feedstock or the possibility of combining technologies can lead to very interesting outcomes.<\/p>\n
Technology alone is usually not enough to develop a market. But combined with a need and opportunity the combination can gain a foothold and lead to a revolution. As we\u2019ve seen in the pages of Biofuels Digest, recent advances in gene-related technologies are poised to revolutionize the way biorefineries operate. These advances will also lead to expansion the scale and scope of biorefinery-based production.
\nWe\u2019re Gonna have a Synthetic Biology Revolution<\/p>\n
Revolutions often start small and build tremendous momentum. Think about how silicon chips led to advances in computing, software and to current trends in robotics, artificial intelligence and the Internet-of-Things.<\/p>\n
We are in a genetic revolution that is, and will continue to, influence how food, fuels, chemicals and materials are produced. Driven by the need to sustainably meet the basic living requirement of growing population and limited resources, the revolution is occurring through a confluence of opportunity and technology. The genetic revolution started when the ability to \u201ccut and paste\u201d DNA, known as recombinant DNA, occurred in the early 1970\u2019s. This spark led to enhanced ability to both analyze genetics and build custom DNA molecules and genetic engineering. Half a century of creative thinking application of computing power has brought us to the current state of synthetic biology.<\/p>\n
In the same way that software and applications are becoming integrated into every part of our lives we will see that biology, enabled by synthetic biology, will transform manufacturing and agriculture.<\/p>\n
Synthetic biology is a confluence of technology that goes beyond simple genetically modified organisms (GMOs) of the past. The ability to make precision edits in DNA sequence using CRISPR and related techniques is being combined with sophisticated computer analysis like machine learning that can be used to \u201cevolve\u201d genes. Natural evolution takes place over millions of years, selecting mutated genes that are best-for-the-immediate task. Synthetic biology uses a variety of gene alteration methods and speeds up the process, allowing millions of mutations to be tested over weeks or months. Because it\u2019s being applied to a closed system, like a better enzyme for ethanol fermentation, these improved enzymes can then be used to speed up reactions or to expand functionality.<\/p>\n
But synthetic biology, like nature, does not live in a vacuum. Combine the ability to engineer genes with advances in nanomaterials, microfluidics, robotics and artificial intelligence and truly revolutionary results are not out of the question and an entirely different biorefinery is possible. Now functionality can be either scaled down to micro scale or even be used to create complex functionality. Machines will mimic living tissues, essential collections of enzymes, nanomaterials and microfluidics that are controlled by an intelligence system.<\/p>\n
One example is the confluence of technologies being used to create biorefineries for \u201cclean meat\u201d production like beef, poultry and seafood. The twist here is that these products are not only muscle cells that are being manipulated to replicate the taste of animal flesh but they are also employing 3D printing to make edible scaffolding upon which the meat cells can self-assemble to make a product that looks and feels like the original.
\nReality Check<\/p>\n
The future can be a long way out or it can be tomorrow. It\u2019s important to keep a perspective on what\u2019s possible and the time required between a discovery and development of a commercial product. Nothing will kill your investment pitch faster than proposing an amazing technology improvement without showing how it bolts-on or drops-in to an existing process. Remember that even synthetic biology needs to be compatible with existing production systems and logistics chains.<\/p>\n
It\u2019s exciting to imaging a full-on, synthetic biology-enabled world where any feedstock can be processed into all manner of useful products in a simple kitchen appliance and no doubt we will see such innovation in time.<\/p>\n
But let\u2019s take a step back to 2018 and examine the trends in synthetic biology that we will see in the foreseeable future.
\nSynthetic Biology Impacts on the Biorefinery<\/p>\n
The following short list of examples is all built on the current reality and some are commercially viable. Think about how refinement will impact the next few years\u2026sort of like the difference between first generation cell phones and what we use now. Look for greater variety, increased scale and increasing specialization.<\/p>\n
Gene editing technology like CRISPR will replace conventional genetic engineering (GMO) leading to:<\/p>\n
Easier regulatory approval for modified plants and microbes.
\nFaster and cheaper development of improved feedstocks.
\nCustom-built fermentative microbes.
\nMore efficient and faster enzymes.
\nGreater range of biorefinery products.
\nHigh value chemical production at small scale.<\/p>\n
Molecule screening, DNA sequencing and machine learning software will merge into systems of identifying bio-based products that replace synthetic chemicals.<\/p>\n
Secreted chemicals from microbes.
\nFaster cycle for new product development.
\nMixtures of microbes in reactor vessels.
\nDirect application of microbes to crops in the field.<\/p>\n
3-D printing and microfluidics integration into biorefineries will enable:<\/p>\n
Long chain and branched molecules.
\nProgressive reactions.
\nFormation of complex structures.<\/p>\n
The list goes on and the possibilities are endless given a long enough time frame. The point here is that the future biorefinery will be a stepwise evolution of the current biorefinery\u2026except that the speed of discovery and its implementation will be enabled by the synthetic biology revolution.<\/p>\n","protected":false},"excerpt":{"rendered":"
