NAWARO CASCADING PILOT
Endbericht
Summary
Future oriented added value means getting together the two areas of material and
energetic utilisation of biological resources. The current goal is to promote the use of
renewable primary products as biomaterials and at the same time to keep an eye on
energetic use.
It is a well known fact that ‘produced’ waste costs money several times. On the one
hand the appearance of waste in any process means that less than 100 per cent of
the input materials are being used, which means hidden extra costs. Additionally,
you have to pay for disposal. The cascading approach offers a solution for both
problems: a complete utilisation of the primary products means an efficiency of
almost 100% in the production chain and at the same time eliminates undesirable
and harmful waste. The goal is to achieve added value throughout the production
process by profitable cascading of incidental by-products. In the long run, linear
chains of production with little interaction are to be replaced by systemic and
networking production clusters.
The main goal of our research project was to fathom innovative usage options for
fruit stones as by-products of agriculture and fruit processing industries. Cascading
also means to pursuit the principle of multifunctionality – the ability of a product to
offer several services at once. Thus we have aimed our research and development
works to answer the following questions:
• How can the stones of cherry, apricot, peach and prune be extracted, cleaned,
broken and split into utilisable components (hard shell and soft core)?
• Is it possible to extract oil from the stones, of what quality is that oil and what
can it be used for?
• What parts are of what use?
• What products can be gained directly from the stones and accordingly from
the oil, the press cake and the hard shells and what are the future prospects?
Backing this up is the conviction that a great, not yet utilised potential of precious
natural products can be provided for all kinds of usable areas via the development of
cascades. To avoid the waste of fruit stones and utilise the precious substances of
content, it is necessary to find technical and sustainable systemic solutions that make
the immanent multifunctionality of fruit stones available.
Results
The results of the survey at hand NC-PILOT have deepened the basics research of
NAWARO CASCADING, led to the planning of mechanical processing of fruit stones
and broadened the options of product development. The logistic, procedural and
