Environmental applications of poplars and willows
Working Party Meeting 17 and 18th September 2000
The 2010 meeting was hosted by the Institute of Agro-Environment and Forest Biology (IBAF) and the National Research Council in Montelibretti. Participants would like to thank Angelo Massacci and his team for organizing an excellent meeting. Thirtyfive participants from nine countries attended the meeting which comprised presentations, a poster session, a visit to facilities at IBAF and a field trip on the second day.
Ten presentations were made on a variety of environmental applications of both poplar and willow. Topics included erosion control on slopes, protection of rivers from agricultural run-off, using poplar and willow as a barrier for excess sediments, the use of willow as living walls to provide a barrier to both noise and graffiti, the phytoremediation of landfill leachates and waste water general, of heavy metals and of a variety of organic pollutants including perchloroethylene, polycyclic aromatic hydrocarbons, diesel, and pharmaceuticals. There followed a discussion about using the wood after phytoremediation applications, particularly for bioenergy production. Several of the talks described using wood chips for electricity generation. Co-firing the chips with coal is seen as an effective way to reduce harmful emissions and generate power with current technology, but there needs to be such an end-user close to the site of biomass production to be economic under most situations. Concerning the release of pollutants, especially heavy metals, into the air or in the ash, it was pointed out that coal firing can results in high levels of mercury, so any reductions in coal would be beneficial. Also flue gas cleaning systems are designed to capture pollutants. In addition, poplar and willow have been found to retain most of the heavy metals in the roots rather than translocate it to aboveground tissues, so that pollutants are not transferred offsite in harvested biomass. There was also discussion on the importance of selecting the proper clones for the geographical location of a proposed site and that using a variety of clones to reduce loss of production due to pathogens.
The tour of the research centre facilities included a small experimental combined heat and power unit that used the poplar chips from the research station for producing electricity and heat for use on site. The poster session and business meeting followed. The business meeting discussed the need to better promote the WP6 website, asking members to link their own websites to the IPC site. Options for the next WP6 meeting included either linking it with the International Phytotechnologies meeting to be held in Portland, Oregon (USA) in September 2011 or with the annual meeting of the Poplar Council of Canada to be held in Edmonton, Alberta (Canada) in autumn 2011. Preference was given to the Canadian option since volunteers came forward from the meeting participants to help organize it.On Saturday, the meeting travelled to Colleferro in the River Sacco Basin, to visit a 90 ha poplar plantation on land closed to agricultural activities due to contamination by the pesticide lindane. Selected poplars are under trial to determine their effectiveness at soil cleaning by enhanced rhizoremediation with associated biomass production. This was followed by a visit to the Business Innovation Center of Lazzio (BIC Lazzio) to view a biomass fired trigeneration plant using a microturbine and boiler developed by the University of Rome. The plant has an energy conversion capacity of 1,050 tonnes/year biomass and supplies the BIC with all its heating, cooling and electricity needs. Professor Cordiner provided details of the plant which operates on mixed biomass including poplar, residues from olive oil production, and forest residues. Excess heat is used to dry the biomass prior to energy conversion. Massimo Tarchi, the experimental research manager at BIC Lazzio presented the project on phytoremediation of Lindane, and Angelo Massacci discussed his project on the phytoremediation of Lindane by inoculating poplar with specific rhizospheric bacteria capable of utilizing the pollutant as a sole carbon source. The inoculum nearly tripled the effective rhizodegradation of this pesticide.
