Description: Jonathan Kays, Forestry Extension Specialist, University of Maryland Extension, will present on the Deep Row Entrenchment (DRE) of biosolids using hybrid poplar.
Biosolids, formerly known as “sludge,” refer to the residual materials removed from sewage during the wastewater treatment process. Biosolids are commonly applied to land for beneficial utilization, but it has become increasingly difficult to apply these biosolids on land due to nutrient management regulations, accelerating land prices, the disappearance of farm land, and social issues surrounding odors.
The utilization of biosolids using short rotational crops of hybrid poplar trees solves many of the problems associated with traditional biosolids application methods and holds great promise. Deep row entrenchment (DRE) is a biosolids beneficial reuse system that uses a one-time application of biosolids in wide and shallow trenches covered with overburden, and planted with hybrid poplar cuttings. Years of research by Gary Felton, water quality specialist, and Jonathan Kays, on a gravel spoil in southern Maryland demonstrated minimal impacts on water quality and revealed how this beneficial reuse system is best applied on gravel and coal strip mines for reclamation. Case studies showing the applicability of DRE for coal strip mine reclamation will be discussed.
The University of Maryland Extension just released a new 48-page extension bulletin on best practices for deep row entrenchment of biosolids (EB453). This publication provides best management practices resulting from years of research by the University of Maryland on a private gravel spoil site in southern Maryland. Application of the technique to coal mine spoils is discussed.

Louis Licht, CEO, Ecolotree
Description: Modern phytoremediation manages Contaminants-of-concern (COC) each with specific legal permit requirements. Three different phytoremediation case histories will be detailed: a. A 15-acre landfill cover irrigated 15 million gallons of leachate treatment in Chicago; b. Panelview RV park with 5,000 gallon/day waste water treatment in rural Oregon, c. Urban industrial groundwater solvent plume irrigated onto an on-site buffer in Seattle.
Poplar/willow genetics allow construction of a robust and predictable reactor treating 'pollutants'. The Salicaceae rhizosphere pumps carbon and oxygen in and water out of the subsurface growing media. Sugars and proteins made by leaves move down phloem to grow roots that leak food for the attached microbes. With dense deep roots a root zone can grow a mixed microbe mass with greater diversity and activity. COCs adsorb and mineralize year-round even in dormancy because of stored carbon deposited by summer growth.
Ecolotree started planting in 1988. After 33 years planting trees around the country, over 50 EBuffers and ETCaps are functioning well. These technologies have a lower carbon footprint than other pollutant removal techniques. With a strong permit that takes full advantage of the rhizosphere reactor treatment capacity, a phytoremediation system can help keep the owner of liability in compliance. Greatly reduced operating costs often increase the value of a property.

Timothy Volk, Senior Research Associate and Associate Chair, SUNY College of Environmental Science and Forestry
Description: Biomass for bioenergy, biofuels and bioproducts can be sourced from multiple feedstocks, including short rotation woody crops (SRWC) such as shrub willow (Salix spp.) and hybrid poplar (Populus spp.). Shrub willow grows rapidly on a range of sites including marginal land and former industrial sites, and provides numerous environmental benefits. The GHG balance of these systems is a key attribute and there is a need to understand the GHG impact as we strive to address climate change. This presentation will highlight recent results from studies including a spatial LCA of willow, a willow to biofuel process, and in a situation where willow is being used as evapotranspiraton cover instead of a geomembrane of clay cover. In all these situations, under certain conditions, the willow system is capable of a negative GHG impact; meaning it can take up and store more carbon than is released from all the other steps in the process. Contributing researchers: T.A. Volk, O. Therasme, T. Koch, Z. Tariq, and M. Eisenbies.

Christopher C. Bowland and Amit K. Naskar, Chemical Sciences Division, Oak Ridge National Laboratory
Description: Lignin is the second most abundant plant biomass material. Finding value of lignin is critical to the cost competitive production of biofuels. However, utilization of lignin as a feedstock for value added materials remains very limited due to its hyper-branched oxygenated structures and characteristics associated with such structures e.g., high rigidity, low thermal stability and poor processability either in melt or solution. We address these challenges by dispersing oligomeric lignin domains in a compatibilized rubbery matrix. Significant improvement of the mechanical properties and processability with high lignin content in our new composite materials (40-70 wt%) offers a new opportunity for automotive and building applications. Formation of a networked structure by covalent or ionic crosslinking of lignin in rubber matrices with different polarities results in tunability of the glass transition temperatures of the composite and high stiffness and strength as well as additional shape memory effects. We also find that the hydroxyl groups of lignins could also be cross-linked with telechelic polyethylene oxide to make self-healing elastomers.

Robin Clark, Oak Ridge National Laboratory and Center for Bioenergy Innovation
Description: The Center for Bioenergy Innovation (CBI) vision is to accelerate domestication of bioenergy-relevant, non-model plants and microbes to enable high-impact innovations at multiple points in the bioenergy supply chain. A key focus of CBI R&D is overcoming barriers to supplying high-yielding, robust feedstocks by accelerating science to identify and utilize key plant genes for growth, yield, and composition for two perennial feedstocks - poplar and switchgrass. In this presentation, members of the CBI Economics & Sustainability Analyses Team will discuss recent work to develop techno-economic assessment (TEA) models for quantifying the impacts of CBI fundamental R&D in poplar development and sustainability to reduce barriers that impact the entire feedstock supply chain. These models will be integrated with a conversion TEA model and sustainability analyses to create a set of field-to-end product analytical tools to predict potential impacts of CBI research on industrial cost and sustainability barriers. By applying a holistic assessment of the design, these TEAs will provide rapid feedback to experimentalists and will serve as a decision-making tool for dynamic project management. Our presentation will highlight recent analyses for two critical questions in prioritizing poplar genetic improvements: 1) comparing the relative impacts of poplar composition and poplar yield on the economics of biofuel production, and 2) assessing tradeoffs between maximizing poplar yield and yield stability to design low-risk biomass feedstock supply chains.

Bacterial Canker Disease on Populus × euramericana caused by Lonsdalea populi in Serbia
Milica Zlatković, University of Novi Sad, Serbia
Description: Populus × euramericana (Dode) Guinier clone (cl.) “I-214” was introduced into Serbia in the 1950s and has become one of the most widely grown poplar species. In September 2019, cankers were observed on stems and branches of P. × euramericana cl. “I-214” trees in the province of Vojvodina, Serbia. The canker tissue was soft and watery, and a colorless fluid that smelled rotten flowed from the cracks in the bark. After two weeks, diseased trees experienced crown die-back and oozing of foamy, odorous exudates. In this webinar we will discuss the symptoms of a bacterial disease on P. × euramericana caused by Lonsdalea populi.

Water Use Efficiency of Poplars Grown for Biomass Production in the North Central United States
Andrej Pilipović, University of Novi Sad, Serbia
Description: Site conditions, especially water availability, significantly contribute to the productivity of poplar biomass plantations and often affect the performance of different clones due to G×E interactions. Proper use of clones or cultivars must consider selection of genotypes with high water use efficiency (WUE) that maximize yield for the available amount of water on site, while avoiding drought stress and growth impacts to the trees. During drought, stomatal closure induces increased amounts of accumulated δ13C carbon isotope in plant tissues that strongly correlates with WUE of plants and can be used as a parameter in selection of drought tolerant and productive genotypes. This presentation will elaborate the evaluation of WUE efficiency among genotypes grown at different sites in the Midwestern United States with aim to identify genotypes with high WUE for future deployment on water-limited sites in the region.
Carbon Sequestration Potential of Short Rotation Eucalypts
Don Rockwood, Florida FGT LLC, USA
Description: Intensively grown Eucalypts can be very productive SRWCs in various management scenarios that influence carbon sequestration rates. Biochar produced from Eucalypts may in turn be a useful soil amendment for Eucalypt culture and thus an opportunity to increase sequestration further.
