Site permeability, clay content, depth to water table, and organic content can impact technology performance. 

The vegetation used to extract toxic metals may pose a risk to animals that consume these plants. Animal consumption of process plants could also result in harmful metals working their way up the food chain. Hyperaccumulation is a much slower process than most chemical and physical technologies, and its performance is typically measured in months or years. Technology effectiveness is limited by root growth thus, wastes must be relatively close to the surface. In addition, the toxicity of the targeted contaminants and other site-specific characteristics such as pH, soil characteristics, nutrient content, and water availability can impact technology performance.

The dynamic sorption apparatus clearly demonstrates the advantages of performing dynamic rather than static measurements of spreading and penetration at microscopic resolutions on substrates as complex as paper. The ability to observe ink or toner/paper interactions in situ should be especially valuable for investigating other non-impact technologies. 

In the history of PU, some continuous processes for polyether polyol synthesis by anionic polymerisation were developed, but only at small scale (i.e., pilot plant). Tubular reactors with static mixing systems or a column with plate reactor types were used, but these technologies were not extended to industrial scale levels. The first continuous process for high MW polyether synthesis was developed by Bayer (IMPACT Technology) and is based on the very rapid coordinative polymerisation of alkylene oxides, especially PO, with dimetallic catalysts (DMC catalysts - see Chapter 5). A principle technological scheme of a polyether polyol fabrication plant is presented in Figure 4.30.

Before any remedial measures are taken, it is assumed that a site survey will be undertaken to establish the structural condition of the SNF containers and evidence of radionuclide leakage. In view of their relatively low levels of activity, this section does not address the issue of remedial measures for non-SNF radioactive material. Also, no attempt is made to assess the need for remedial measures, as it is beyond the remit of the Group. However, an estimate is provided below of the physical condition of the SNF containers to assist in any assessment of necessary or feasible actions. It is up to other expert groups to assess whether the environmental impact, technologies, and cost considerations render such actions necessary and or feasible. 

Effort must also be made at the industrial level in order to develop less expensive and higher performance products and low-impact technologies. Policies should therefore be focused more on supporting innovation and scale up of new technologies which can create solid added value and are capable of responding to the societal challenges faced by our planet.
