A questionnaire survey was carried out in four European countries to gather end-user's perceptions of using plants from phytotechnologies in combustion and anaerobic digestion (AD). Nine actors of the wood energy sector from France, Germany, and Sweden, and eleven AD platform operators from France, Germany, and Austria were interviewed. Questions related to installation, input materials, performed analyses, phytostabilization, and phytoextraction were asked. Although the majority of respondents did not know phytotechnologies, results suggested that plant biomass from phytomanaged areas could be used in AD and combustion, under certain conditions. As a potential benefit, phytomanaged plants would not compete with plants grown on agricultural lands, contaminated lands being not suitable for agriculture production. Main limitations would be related to additional controls in process' inputs and end-products and installations that might generate additional costs. In most cases, the price of phytotechnologies biomass was mentioned as a driver to potentially use plants from metal-contaminated soils. Plants used in phytostabilization or phytoexclusion were thought to be less risky and, consequently, benefited from a better theoretical acceptance than those issued from phytoextraction. Results were discussed according to national regulations. One issue was related to the regulatory gap concerning the status of the plant biomass produced on contaminated land.
在四个欧洲国家开展了一项问卷调查，以收集终端用户对在燃烧和厌氧消化（AD）中使用植物修复技术中的植物的看法。采访了来自法国、德国和瑞典的九位木材能源行业从业者，以及来自法国、德国和奥地利的十一位厌氧消化平台运营商。询问了与安装、输入材料、进行的分析、植物稳定化和植物提取相关的问题。尽管大多数受访者不了解植物修复技术，但结果表明，在某些条件下，来自植物管理区域的植物生物质可用于厌氧消化和燃烧。作为一个潜在的好处，植物管理的植物不会与在农业土地上种植的植物竞争，因为受污染的土地不适用于农业生产。主要限制将与对过程输入和最终产品以及可能产生额外成本的装置的额外控制有关。在大多数情况下，植物修复技术生物质的价格被提及为潜在使用受金属污染土壤中的植物的一个驱动因素。人们认为用于植物稳定化或植物阻隔的植物风险较小，因此，与植物提取产生的植物相比，理论上更容易被接受。根据国家法规对结果进行了讨论。一个问题与受污染土地上生产的植物生物质的地位的监管空白有关。
