As scientists and engineers work to create more efficient biofuels, there is one step of the process that remains expensive and, in some circumstances, inefficient for large-scale production.
One of the most significant challenges of cellulosic bio-refining has been and continues to be the development of effective and low-cost pretreatment technology, which is one of the first steps in the biofuels production process.
WSU Tri-Cities doctoral student Libing Zhang traveled from her homeland of southeast China to attend WSU for her doctoral program because of the research WSU is conducting in this field.

Six students at Washington State University were crowned champions of WSU’s Fifth Annual Global Case Competition, Friday, April 10, 2015.
The victorious group, under the name Team Verde, consists of a pair of graduate students from the WSU Spokane campus, team captain Emma Henselbecker and Sara Dumit, as well as four undergraduates from Pullman, Brandon Hernandez-Cantu, Emelia Stephan, Kimberly Rogers and Ivan Valdovinos. The faculty advisor is Grant Norton of the Honors College.
This year’s case centers on plastic waste in Manaus, Brazil with over 120 participants. Five finalist teams were selected to present their solutions to a panel of judges. Team Verde members will now have the opportunity to travel to Brazil for further study.
The second place team, Cougar Cogeneration, consisted of Sergio Baravalle (BSE), Annalise Miller (CAS, Math), Stephanie Gardiner (NURS, Nursing) and Philip Behrend (CAS, Math), and advised by Chuck Pezeshki (Voiland College of Architecture and Engineering) not pictured.
Slide 1: Briefly, while thinking about the challenge, we wanted to make sure to involve and align the main stakeholders in the community, including the poor class, middle class and industrial sector in order to solve the serious problem of plastic waste in Manaus Brazil.
Slide 2: Manaus is a remote area in the middle of the Amazonas that relies on expensive energy from fossil fuels to feed its growing industry sector. This situation creates a suitable environment for the development of sustainable and profitable solutions since relatively cheap raw materials are available to produce energy from non-recyclable plastic waste.
Based on that situation and leveraging on technologies and concepts in the BSE Department, we developed a solution that is technically feasible and profitable. It considers social aspects, taking scavengers out of the landfill and providing them with a sustainable income, managing a sorting facility. We also considered a sanitary program developed by a member of our team who is studying nursing.
The practical solution considers the gasification of the nonrecyclable plastic in a cogeneration plant. This plant has the capacity to produce electric power while distilling polluted water for poor people that are currently drinking contaminated water.
Slide 3: While we were developing the project we were aware that the scope was too large for a group of students to manage. However, we wanted to consider the situation holistically, perhaps one day working with WSU as ambassadors to Brazil. Numerous resources are available at WSU to support this endeavor.
The electricity would be sold to the grid and according to our calculation and benchmarking studies, the project is profitable.

WSU On Solid Ground | June 2014
If you’ve ever enjoyed the summertime taste of fish, chicken or steak grilled over charcoal, you have benefited from pyrolysis. The very same technology that produces charcoal is also a cornerstone for making the vision of a commercial, wood-based biofuels industry in the Pacific Northwest a reality.
Scientists like Manuel Garcia-Perez and his graduate students, who study biosystems engineering at WSU, are helping to nurture the emerging biofuels industry by developing pyrolysis technologies.
Through pyrolysis, biomass like wood, grass, and other organic material is exposed to high temperatures in the absence of oxygen. The result is bio-oil, a precursor to biofuel, as well as other useful products like charcoal, or biochar.
“The low-hanging fruit for commercializing the technology to convert biomass to energy comes from sources like construction debris, for example, that are concentrated in one location,” Garcia-Perez said. “But in cases where the biomass is spread out over a large region, as with forestry waste, transportation to a processing facility can be expensive.”
Pyrolysis road show
One solution the wood fuels industry is exploring is the development of mobile pyrolysis units, or reactors, which can process the raw material right where it’s collected in the forest before transporting the resulting bio-oil to a refinery.
Nine WSU graduate students in Garcia-Perez’s lab were invited to share their knowledge of pyrolysis and evaluate the products of two different mobile pyrolysis units developed by Amaron Energy and Western Renewable Technologies during a recent demonstration in Bingen, Washington. The Washington State Department of Natural Resources sponsored the event in order to offer the public and industry a chance to learn about the technology.
In addition to providing background and sharing information about their research projects with more than 120 visitors, the students also collected samples of the bio-oil and biochar for testing back at the lab in Pullman, Washington. How much oil versus biochar did the two units produce? What was the quality of the products, how did the two units compare in terms of pollution? They will share these answers with the Department of Natural Resources and the two companies later this year.
Students, society benefit
In one day, the students collected bio-oil and biochar samples that would otherwise take days or weeks to produce in a lab. Perhaps more valuable, however, was the opportunity for students to meet people in the industry who build pyrolysis systems as well as policymakers who are interested in how the technology might serve society.
“Because we’re usually working on our projects in the lab, it’s hard to get perspective of what the industry wants,” said Brennan Pecha, a doctoral student in Garcia-Perez’s lab. “It was really nice to get a feel for who is actually producing reactors and using research like ours.”
The mobile technology shows promise but Garcia-Perez cautions that it’s not a solution for all types of biomass and situations. Although the mobile units are much larger than those Garcia-Perez has in his lab, their size is a limiting factor for achieving an economy of scale. Another limitation is that the technology to refine bio-oil is not yet at a stage where it is ready for commercialization.
But Garcia-Perez remains hopeful. Ultimately, a wood-based biofuels industry is intended to reduce our reliance on fossil fuels. And when used as a soil amendment in agriculture, biochar can help reduce greenhouse gas emissions by sequestering carbon in the soil.
“Mobile pyrolysis units are not yet commercially viable and the technology to refine bio-oil is still developing, but it has the potential to be a great benefit to society,” he said.

A different way of producing biofuels is to use crop residues and woody materials as the source for the fuel. Those materials are full of cellulose and a molecule called lignin. The lignin is bonded to the cellulose within each plant cell.
Professor Shulin Chen of Washington State University is one scientist studying what termites do with an eye toward adopting similar processes to make biofuels from crop residues and woody materials. read full article
