approaches to waste
Approaches to waste

Re-design processes for waste minimisation

Fractionate to added value products

Stabilise, reduce, recover value (material or energy)

Stabilise, reduce in volume

Segregate

added value products
Added value products
  • Phytochemicals / nutraceuticals
  • Anti-oxidants
  • Colourants
  • Fibres
  • Vitamins
  • Flavinoids
  • Pectins
  • Saccharides
  • Carotenes

…and we call this stuff waste!

fractionation1
Fractionation
  • Separation of useful material is nothing new
fractionation2
Fractionation
  • Separation of useful material is nothing new
  • Segregation of waste is a necessary preliminary discipline
fractionation3
Fractionation
  • Separation of useful material is nothing new
  • Segregation of waste is a necessary preliminary discipline
  • Fractionation achieves molecular scale separation and disruption of problematic structures, enabling isolation of added value materials.
routes to fractionation
Routes to fractionation
  • Physical
    • centrifugation, membrane separation
  • Chemical
    • chemical hydrolysis, extraction
  • Bio-chemical
    • enzymatic transformation.
a few examples
A few examples

Total Foods 2004, Institute of Food Research, Norwich

Phytochemicals by chemical extraction / column exchange

…from vegetable residues

F.A. Tomas-Barberan, CEBAS (CSIC) , Murcia

…from apple pomace and mango peels

A. Schieber et al., Hohenheim University

Functional foods from fish waste

E.O. Elvevoll, Univ. of Tromso

Extraction from herbs and tomato residues using supercritical CO2

E. Vagi. B. Simandi, Budapest Univ. of Techn. And Economics

a few examples1
A few examples
  • Enzymatic deconstruction of cell structures to facilitate upgrading of waste

e.g. Brewer’s grains, wheat bran to yield phenolic acids and fractionated polysaccharides

K.W. Waldron et al, Institute of Food Research

  • Juice production from carrot waste

Provalor BV / TNO-MEP Apeldoorn

  • Purification by industrial affinity chromatography

CatchMabs BV, Wageningen

re design processes
Re-design processes
  • Maximise resource utilisation and avoid waste
    • Technical innovation – better unit operations
    • Information processing and decision making.
improved unit operations
Improved unit operations

Waste arises from the failure of processing operations.

information and decision making
Information and decision making
  • Forecasting and scheduling
    • demand forecasting, production scheduling
    • weather forecasting UK Foresight Programme
    • Integrated supply chain issue
  • Production yield analysis
    • Re-evaluate yield, losses, waste, product specification etc.

M.A.J.S. van Boekel, Wageningen University

information and decision making1
Information and decision making
  • Sustainability analysis tools applied to decision making about waste management, recycling etc.
    • e.g. utilisation of energy as animal feedstuff versus energy recovery technologies
  • Waste “account” information
    • Informed decisions without information on amounts, nature, patterns?
    • Greater and sustained national level investment and co-ordination required.
