Woodzymes
Several crucial steps in wood industries involve extreme operation conditions (such as high temperature and pH) to remove or modify recalcitrant lignin that protects cellulose in the plant cell wall. Enzymes can substitute harsh and energy-demanding chemical treatments for sustainable production of bio-based building blocks and products in wood biorefinery. However, wild enzymes, evolved to act under natural environmental conditions, cannot be integrated into the current industrial processes. WoodZymes project aimed to develop and optimize extremophilic enzymes resisting very high temperature and pH, to be used as biocatalysts in wood industries. These extremoenzymes were applied to recover phenolic compounds from enzymatic breakdown of technical lignin, as well as lignin and hemicellulose compounds from enzymatic delignification and bleaching of kraft pulp (also resulting in more sustainable final cellulosic pulp). The extremophilic enzymes were also used to valorise the latter compounds as bio-based precursors for adhesives in the manufacture of medium-density fibreboards, and as components of insulation polyurethane foams (substituting fossil building blocks), as well as for obtaining renewable sugar-based papermaking additives.

A Bio-inspired Multilayer Drainage System
Agricultural run-off and subsurface drainage tiles transport a significant amount of nitrogen and phosphorus leached after fertilization. alchemia-nova GmbH in collaboration with University of Natural Resources and Life Sciences, Vienna developed two multi-layer vertical filter systems to address the agricultural run-off issue, which has been installed on the slope of an agricultural field in Mistelbach, Austria. While another multi-layer addressing subsurface drainage water is implemented in Gleisdorf, Austria. The goal is to develop a drainage filter system to retain water and nutrients. Both multi-layer filter systems contain biochar and other substrates with adsorption properties of nutrients (nitrogen, phosphorus). The filter system can be of practical use if an excess of nutrients being washed out is of concern in the fields of the practitioner by keeping the surrounding waters clean. This approach may result in economic value by re-using the saturated biochar as fertilizer and improving the soil structure, thus increasing long-term soil fertility.

NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY
This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735. FACTSHEET NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY Key information Functionalized nanocellulose membranes can take up nitrate and phosphate. These membranes can be put in a water treatment unit. As the membranes are biobased, degradable materials, they can after use be added to the soil, thus returning the leached nutrients back for their original purpose providing fertilizers (nutrient recycling).
Environmental monitoring within greenhouse crops using wireless sensors
Because variables such as temperature and humidity have a profound effect on the activity of crop pests, diseases and natural enemies, the ability to monitor environmental conditions within a crop has always been important for crop protection.
