Moulded pulp products are widely used in the packaging industry. Egg cartons are a common example of this method. Their environmentally friendly qualities have seen moulded pulp products increase in popularity in electronics packaging, where they are used to replace materials such as styrofoam.
In our experience, short peat fibre can be used at concentrations of 20–30% to replace recycled fibre in moulded pulp products. The availability of high-quality recycled newsprint fibres is declining year by year as digitalisation reduces the demand for traditional newspapers. This forces industries that use recycled fibres to seek alternative sources of fibre, with peat fibre being an interesting option.
The special properties of peat fibre that are highlighted in moulded pulp products include its hydrophobic, oleophilic, antibacterial and fungistatic qualities. The final characteristics of moulded pulp products are determined by the relative proportions of the fibre mixtures and other components used.
Moulded pulp products containing peat fibre can be composted and disposed of in energy waste.
Ecopulp is a manufacturer of moulded pulp products in Kouvola, Finland. “We have introduced peat fibre as a complement to our primary raw material, which is recycled paper. Peat fibre is a clean natural product that does not contain ink or any of the chemicals used in paper production. That is an important consideration in products such as our plant protectors. The peat fibre decomposes in nature in only a few years, once the planted seedling has grown to a sufficient size and no longer needs protection,” says Ari Henttonen, Managing Director of Ecopulp.
