AZTI-Tecnalia investigates the aprovechamiento of vegetal by-products for animal feeding
Clean Feed, funded by the Program Life+ of the European Union and cofinanciado by the Direction of Innovation and Alimentary Industry and the Direction of Environmental Quality of the Basque Government, results of big importance in the aim to avoid that biodegradable products go to stop to the dumps. In Euskadi, roughly the three fourth parts of the more than 25.000 tonnes of products and vegetal by-products that generate finish in the basureros. To contribute to paliar this circumstance, AZTI-Tecnalia is working in the characterisation of the different vegetal fractions generated in the CAPV, by means of the preparation of a ‘inventory of generation', the realisation of a sampling and analytical of laboratory. All this with the aim that it can evaluate the idoneidad of the different vegetal by-products to be incorporated in piensos.
The different sectors of the alimentary industry that generate vegetal by-products are the sector of the potato (29,6%), the wine (27,7%), the distribution (16,6%), the sidra (13,8%), the bread (11,3%), the sector horto-frutícola (0,8%) and the coffee (0,1%). AZTI-Tecnalia has realised an exhaustive compilation of information of these sectors in relation with the quantities, characteristics of generation and current management of his by-products.
Process of sampling and analytical of laboratory
The technological centre expert in marine and alimentary investigation has defined three phases of sampling —spring, summer-autumn and winter—, in such a way that it take into account the estacionalidad in the typology of the vegetal by-products of each sector. It has designed, to his time, a protocol of sampling and has selected the most significant companies of each sector, with the end that the samples obtained are the most representative possible.
The samples are processed for his sending to the laboratories of the technological centre. The parameters of analysis have been selected with the aim to evaluate the idoneidad of his incorporation in the formulations of piensos. The samples have to fulfil the nutritional requirements, of market and legislative established for animal feeding.
The results of the analytical of the first phase of sampling, waiting for being corroborated by the analytical of the others two phases of sampling, stand out the high content in humidity, above 80%, low values in protein and fat, underneath of 1% in both cases, as well as values around 5% in total sugars and to the 1-2% in total fibre. With regard to the presence of undesirable substances, does not stand out the presence of any anomalous value.
In addition to the analytical studies, the project Clean Feed pretends to pose a technical solution for said by-products and realise a pilot experience to scale real that allow to validate it and fine-tune it. The aim is to develop a plan of effective and viable performance, for the handle, treatment, management and control of the vegetal fractions for his aprovechamiento in animal feeding.
Reduce the quantity that arrives to the dumps
Roughly the three fourth parts of the more than 25.000 tonnes of fruit and vegetable no commercialised and other vegetal by-products go to stop to the dumps of the Basque Country, where are managed like waste. In the case of the fruit and the vegetable, treats of products that are not commercialised because of criteria of market (bad presentation, forms little attractive, vicinity to the date of caducity, etc.); in the case of the by-products, these derive of productive processes and of transformation of the alimentary industry.
The current politics in matter of waste base in the reduction of the biodegradable waste that are allocated to dump. A directive of the European Union and Second Plan Mark Environmental of the CAPV signal for 2012 the intention to reduce in 50% the biodegradable waste that finish in dumps. Likewise, the draft of the III Plan Mark Environmental of the CAPV 2011-2014 establishes like aim Increase the tax of valorisation of waste no dangerous, in 5% and boost the safe replacement of prime matters by by-products and waste by means of the development of standards and technical rule.
