Monash University has formally opened SMaRT-Pack, an Australian research and training centre developing fibre-based packaging materials, barriers and recycling methods. The opening took place on 6 October 2026 at Monash’s Clayton campus and was announced publicly the following day. The initiative brings together Monash, Deakin University and Queensland University of Technology with international researchers, industry partners and sector associations. It is a five-year programme valued at approximately A$11 million, incorporating an Australian Research Council grant announced in 2025 rather than a new funding award made at the October opening.
The programme will assess straw, bagasse and other agricultural or forestry residues as feedstocks, since their fibre lengths and chemical characteristics can affect the resulting packaging substrate. Potential inputs include straw, bagasse and other plant fibres, which differ in physical length, chemistry and the materials remaining after harvesting. Processing them into consistent packaging sheets may require adjustments to fibre preparation, forming and drying. A suitable raw material supply is only one requirement; the finished substrate must also deliver the mechanical and functional characteristics demanded by the intended package.
Professor Gil Garnier leads the centre under the Australian Research Council’s Industrial Transformation Research Programme, with researchers and industrial partners examining laboratory developments against production needs. Its structure combines materials research with industrial training so that laboratory work can be examined against production and recycling requirements. Participating companies and associations provide routes for examining packaging problems that occur outside a research laboratory, although the centre is not itself a commercial factory. No newly commissioned high-volume packaging line has been attributed to the launch.
Replacing a polymer film with fibre material can introduce moisture and gas transmission problems, particularly where an untreated sheet lacks the barrier properties required for food storage. An untreated paper structure may absorb water or allow vapour and gases to pass through more readily than the polymers it is intended to replace. For dry foods, moisture exposure can affect texture and shelf life; for other products, oxygen transmission may influence quality. SMaRT-Pack will therefore examine bio-based barrier coatings and the interaction between coatings and fibre substrates. The effectiveness of a barrier has to be assessed under defined temperature, humidity and handling conditions rather than inferred from its renewable origin.
Even when the barrier is adequate, a fibre package must seal reliably and withstand forming, filling, handling and vibration during distribution. A formed package may need to run through existing filling equipment, withstand pressure and vibration during distribution, and retain sufficient integrity once opened or handled. Adding a coating can improve protection while affecting how a fibre structure is repulped later. Manufacturers consequently face choices involving material thickness, drying energy, chemical treatment and the ability of a completed pack to meet its food contact requirements. No particular new SMaRT-Pack material has yet been demonstrated as commercially qualified for food contact use.
To evaluate reuse of the material, the researchers will examine how inks, adhesives and coatings behave when collected fibre packaging returns to a pulping process. Repulping separates fibres from one another, but inks, adhesives and coatings can remain with the material or require further separation. Fibres can also change during repeated recycling, with an effect on the strength of the resulting sheet. Researchers intend to study these changes and evaluate methods for recovering or managing additional constituents, recognising that performance of a clean laboratory sample may differ from a mixed real-world waste stream.
The research also covers degradation in compost, soil and water, whose differing temperature, oxygen and microbial conditions can produce different outcomes for a material. Those environments have different moisture, microbial activity, temperature and oxygen conditions, so a laboratory degradation result cannot be treated as evidence that a material will disappear rapidly in every setting. The work includes investigation of microplastic formation and methods of identifying residual material. Understanding those processes can help distinguish compostability claims from evidence about actual behaviour in uncontrolled environments. The centre has not announced a universal degradation time for the packaging materials under investigation.
Cellulose recovered from wastewater or other secondary streams forms another potential feedstock, although its contamination and fibre characteristics will require separate assessment. Such fibres may vary in contamination, length and their ability to form new packaging, requiring treatment and quality checks before any reuse. Where recovered material is intended for a food-related application, extra attention will be needed to the applicable safety and contact rules. The programme’s inclusion of recovered feedstocks does not imply that all fibres reclaimed from wastewater can enter food packaging. Suitability must be demonstrated for a specific process and use.
Because results obtained under different laboratory conditions can be difficult to compare, SMaRT-Pack plans work on common measures for mechanical strength, barriers, recycling and degradation. Mechanical properties, barriers, recycling efficiency and degradation can each be measured in several ways, and conflicting test conditions make material comparisons unreliable. SMaRT-Pack plans to develop shared methods and evidence that could inform standards. Commercial deployment will still depend on repeatable manufacturing, supply of suitable feedstock, energy demand and a workable recovery route. The October opening establishes the collaboration that will study those questions over its five-year programme.
