The main objective of the WP2 is to create a portfolio of characterised valorisable plant and dairy waste streams for producing safety and functional feed which fulfil animal needs.
Food waste streams will be selected according to their importance in food production in EU, their potential nutritional properties, quantities produced, the seasonality, the regulatory issues, the costs and the logistic of waste producers. The waste streams will be fully characterized at molecular level, from a nutritional point of view (main composition, detailed composition of: nitrogen fraction, fibres content, fatty acids content and minor desirable components with potential functionality) but also for detecting possible undesirable components (metals, microbiological contamination, toxins and agrochemicals).
The final selection of waste streams for creating the portfolio will follow these parameters: a) a gross composition suitable to the subsequent technological transformation; b) the presence of components which will eventually confer enhanced functional and/or nutritional properties to the final feed products; c) the absence of obnoxious components of chemical and microbial origin.
The main objective of this WP will be the investigation of conditioning processes from starting materials. These conditioning pretreatments will be addressed to: ease the utilization of the raw wastes; improve their nutritional values in certain processes; ensure the safety of the raw material in terms of microbial safety; decrease the impact of their seasonality by enabling storage of the stabilized food for a smoother production rate and ensure the adequacy of the stabilized waste as a raw material for feed production.
The main objective of WP4 is to produce specific feed additives (fibers, functional protein hydrolysates and active ingredients with different functionalities) from food wastes.
Selective processes for obtaining the feed additives will be developed. These processes will include pre-treatments of the raw material for enhancing the extraction efficiency. The main goal will be to provide a treatment procedure capable of treating different waste sources and mixtures of them.
The feed additives will be fully characterised at molecular level and their functionality will be demonstrated using in vitro models. In addition, the ability of feed ingredients to survive gastro-intestinal tract adverse conditions and to be absorbed at intestinal level will be also analysed in in vitro models.
Feed will be produced from stabilized wastes (WP3) and functional ingredients from waste origin produced at WP4.
Main objectives of this WP will be: Obtain well balanced blends from co-stream substances and key additives with focus on physiological needs of targeted animals; Assess the stability of feed by performing adapted technological trials and to evaluate the most promising incorporation strategies; Adapt the project innovative feed production technologies to maximize the availability of stabilised substances and key additives via encapsulation; Achieve maximum safety and quality parameters by assessing the pre-production prototypes against biological, physicochemical and toxicological assays.
The main objective of WP6 is to scale up the most suitable technologies for waste stabilisation and conditioning, the bioactive production and feed production from the food wastes
This WP will cover the best identified technologies in the previous WPs with a clear objective of obtaining a convenience feed at the lowest cost with maximum possible wastes as co-streams and using the low energy for stabilization and production purposes. Final product will also be assessed in terms of quality and safety.
The main objective of WP7 is to demonstrate the biological efficacy of the functional feed additives and compound feed produced in NOSHAN by performing well-designed animal trials in monogastrics.
The biological effect of compound functional feed on weaning pigs and poultry performance, welfare and meat quality will be determined. The effect of functional feed on animal performance will be assessed by measuring feed acceptance, growth rates, feed utilization and parameters related to gut health (such as faecal consistency, bacterial enumeration/composition, intestinal secretions, etc).
The effect of functional feed on animal welfare will be determined by analysing clinical scores, degree of accurate phase proteins in blood. Finally, the evaluation of the effect of functional feed on quality/safety of meat will be done by quantifying oxidative changes during storage, meat colour changes, cholesterol oxidation product, etc.
The main objective of this Work Package is to carry out the environmental evaluation, using Life Cycle Assessment (LCA) tool, of feed production from food waste following NOSHAN approach. LCA is a methodology that is used commonly to evaluate the environmental load of a product, process, or activity throughout its life cycle.
The outcomes of the NOSHAN project will be validated through the Environmental Technology Verification (ETV) tool that verifies the performance of the techniques for the use of relevant stakeholders
For the analysis, eco-efficiency indicators will be defined and evaluated.
The overall strategy for waste valorisation into feed and feed ingredients will follow the diagram below:
