Highlights

Better, greener plastic products from waste streams

Better, greener plastic products from waste streams

The CSIR has formulated a new biocomposite material using waste sawdust and recycled plastics as an alternative to fossil-based material for Plastech SA. This innovation adds value to two waste streams: sawdust, a byproduct of the sawmilling industry and recycled polypropylene. Using melt extrusion techniques, researchers produced biocomposite pellets suitable for injection moulding and the manufacture of low-cost building materials with a reduced carbon footprint and improved performance.

Maximising the value of underutilised byproducts for a circular economy

Maximising the value of underutilised byproducts for a circular economy

The CSIR Biorefinery Industry Development Facility assists local industry to improve its competitiveness by providing access to specialised analytical and pilot-scale facilities to ensure a more sustainable way of using the country’s biomass resources. Watch.

Technology concept

CSIR broadens access to biorefinery technologies in support of circular economy

The CSIR has hosted its third annual workshop on biorefinery technologies in the circular economy. This session focused on the valorisation of biomass residues from the forestry, timber, pulp and paper industries, as well as agricultural operations using new circular-based technologies in support of industry and small, medium and micro enterprises.

Recovering useful fibres from used potato bags

Recovering useful fibres from used potato bags

The CSIR has developed a technology to recover fibres from used potato bags. Fibres recovered from used potato bags are repurposed to manufacture paper-based packaging materials such as fluting, a corrugated medium used in paper packaging. The use of waste paper offers economic and environmental benefits in line with circular economy ideals. This innovation is co-funded by the Department of Science, Technology and Innovation and the Paper Manufacturers Association of South Africa.

Extraction process

Unlocking high-value products from sawdust biomass waste

The CSIR is developing a protocol aimed at optimising the extraction of xylitol, a high-value product from xylose, a sugar isolated from wood or sawdust biomass. Maximising the value of underutilised byproducts or waste aligns closely with the principles of a circular economy. The new extraction protocol provides comprehensive guidelines for evaluating and processing parameters to convert xylose into an important platform for sustainable bioproducts, particularly targeting the xylitol market.

Our facilities
 

Analytical characterisation laboratory
Analytical characterisation laboratory

Our laboratory has a range of analytical instruments, including the pyrolysis gas chromatograph mass spectrometer. It has instruments for super-critical fluid extraction, high-performance liquid chromatography, ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy and organic elemental analyses. The lab is equipped with a scanning electron microscope with EDX functionality. These analytical tools allow us to characterise biomass feedstock and evaluate newly developed products.

Bench/pilot-scale laboratory
Bench/pilot-scale laboratory

The laboratory has a range of bench-scale and pilot-scale digesters required for the fractionation of biomass into its chemical constituents. It also houses our bench-scale biogas reactor that allows us to evaluate biogas production over a 25-day period. The laboratory supports external ad hoc pulping research and development experiments for large pulp and paper companies.

Scale-up facility
Scale-up facility

The facility houses our bench and pilot-scale biochar reactors as well as the rapid displacement heater digester. This facility allows the team to scale up bench-scale trials to pilot-scale level, with some of the equipment scalable to commercial-scale implementation. It also houses a waste paper recycling plant that enables the team to evaluate different paper waste streams that enable fibre recovery for reuse applications.
