Resource Efficient and Cleaner Production (RECP) in developing countries: Industrial waste minimization for low carbon production in the rice and coffee sectors.

Client

UNIDO (United Nations Industrial Development Organization)

Project dates

2013-2016

Context and objectives

  • Asia and Americas are producing most of the global volume of rice and coffee
  • There is a worldwide increasing demand for Rice and Coffee
  • This results in large volumes rice and coffee processing bio-waste, in particular rice/coffee husks and coffee pulp.
  • An estimated 50% of these volumes are not valorized, and most of the time thrown away or burnt
  • Initiating a RECP process across 2 agro-industrial sectors in 4 countries, and establishing trust-based relationships
  • Assessing and classifying technologies for the valorization of rice husk and coffee pulp
  • Transforming untapped opportunities into concrete business cases with financing options

Outcomes

  • 28 Cleaner Production audits, 2 sector assessment reports
  • 50 RECP measures identified, among them measures with immediate effective cost-savings by implementing energy management systems with almost no investment: good housekeeping and improved maintenance for better electric system control and systematic consumption monitoring resulting in 5 to 10% of reduced electricity consumption.
  • 1 multi-criteria evaluation grid of 25 mature technologies, 2 technical guidance documents
  • 13 pilots projects developed from ideas, 9 currently in the process of implementation, among them 3 projects for improved on site rice husk combustion for paddy drying combined with rice husk briquette production as a coal substituting combustion material for industrial processes in Vietnam and Cambodia.
    Overall estimated impacts: potential of 380 000 tons of waste valorized per year, 270 000 tons of CO2 avoided per year, and 20 million US$ of investment generated
