The RUSTICA projects provides a technical solution to convert organic residues from the fruit and vegetable sector into novel bio-based fertiliser products of high quality that address the needs of modern (organic) agriculture. The project’s ambition goes beyond the simple recovery of nutrients, and also includes the developments of economically viable and environmentally sustainable alternatives to mineral fertilisers with the same or improved agronomic value. The technical solution consists of 5 conversion processes (carboxylic acid platform, microbial biomass production, electrodialysis, insect breeding and biochar production) which can be combined depending on the available waste streams, and integrated with state-of-the-art technologies such as composting. Synergies between the individual conversion processes will be sought and optimized to maximize economic and environmental benefits, and the processes will be demonstrated at TRL7. The resulting ingredients (microbial biomass, mineral nutrient concentrates, insect biomass, insect frass, insect chitin, biochar) will be combined to obtain tailor made fertiliser products adapted to specific crop needs. Parallel with this technological innovation and integration, a multi-actor approach guarantees the implementation potential of the technologies in the agro-food chain, and will lead to sound business models. Several non-technical aspects (environmental and social LCA, legal framework, expected market developments...) will be evaluated in 4 European regions and 1 region in Colombia. Stakeholder involvement at each step guarantees the development of marketable end-products for the fruit and vegetable sector, with a high replication potential to other agricultural sectors. Cooperation with other EUfunded projects working on nutrient recovery from other waste products will stimulate a joint solution to evolve towards a sustainable and circular fertiliser management to close nutrient cycles within and between regions

VOLATILE aims in the development of an innovative Volatile Fatty Acids Platform for the bioconversion of municipal solid bio-waste fraction and sludgy biowaste from other industries. The platform will be integrated in anaerobic digestion. The volatile fatty acids will be recovered continuously using sophisticated membrane technology and will be provided as feedstock / carbon source for value added fermentation approaches such as biopolymer PHA to be tested in material applications, single cell oil as precursor for oleochemical industry as well as long chain unsaturated health-promoting Omega-3 fatty acids to be used as food ingredient or nutraceutical. PHA will be obtained by bacterial fermentations, single cell oil from yeast cultivation and Omega-3 fatty acids via heterotrophic microalgae. The process development will be accompanied with sophisticated LCA study in order to ensure environmental friendly process design. The project will also work on solutions to typical barriers beside others such as quality requirements, continuous and sufficient feedstock supply or interaction between members of value chain using agent-based modelling. Also the effect of legal stimuli and restrictions and subsidies and taxes will be studied and a link between product requirements and markets will be established. VOLATILE will prepare a Roadmap indicating future research needs but also giving suggestion for legislative improvements. A CEN workshop will be initiated to discuss with external stakeholders rules for the VFAP & to set up standard requirements in the form of a CEN workshop Agreement.

The project NANO-CATHEDRAL aims at developing, with a nano-metric scale approach, new materials, technologies and procedures for the conservation of deteriorated stones in monumental buildings and cathedrals and high value contemporary architecture, with a particular emphasis on the preservation of the originality and specificity of materials. The objective is providing “key tools” for restoration and conservation: •On representative lithotypes •On European representative climatic areas •With a time-scale/environmental approach •With technology validated in relevant environment (industrial plant and monuments) •Exploiting results also on modern stone made buildings A general protocol will be defined for the identification of the petrographic and mineralogical features of the stone materials, the identification of the degradation patterns, the evaluation of the causes and mechanisms of alteration and degradation, including the correlations between the relevant state of decay and the actual microclimatic and air pollution conditions. Moreover, innovative nano-materials will be developed suitable for: •Surface consolidation: in this case water-based formulations based on nano-inorganic or nano-hybrid dispersions such as nano-silica, nano-titania, nano-hydroxyapatite, nano-calcite and nano-magnesia as well as their synergic combinations with organic and inorganic compounds will be considered. •Surface protection: in this case, innovative composites will be developed consisting of polymers and nano-fillers. The use of hydrophobins, nano-assembled hydrofobic proteins extracted from fungi, and photocatalytic nano-particles (for favoring the decomposition of volatile organic molecules carried by polluted atmosphere and to prevent biofilm growth) will be considered. The project will contribute to the development of transnational cultural tourism and to the development of common European shared values and heritage, thus stimulating a greater sense of European identity.
