  • the moulded pulp comprises at least 5 wt. non-wood lignocellulosic biomass, with the non-wood lignocellulosic biomass having a protein content below 5 dry wt. %.
  • non-wood lignocuccolosic biomass provides additional visual effects that may provide the packaging unit with a more natural feel.
  • the non-wood lignocellulosic biomass preferably should have a protein content below 6 dry wt.%.
  • a high protein content reduces material strength too much, especially during the manufacturing process wherein side wall of the packaging unit may bend or collapse.
  • the protein content is below 4 dry wt.%, preferably below 3 dry wt.%, more preferably below 2 dry wt.%, and most preferably below 1.75 dry wt.%.
  • dry wt. % can be measured using the so-called Kjeldahl content with a Buchi Kjeldahl lab analysis from which the protein content is calculated.
  • non-wood lignocellulosic biomass improves the flexibility for the use non-wood biomass as starting material when manufacturing packaging unit according to the invention. Furthermore, increasing the amount of biomass improves the natural feel for the consumer. Also, especially in case the biomass originates from a rest flow, the sustainability of the packaging unit is further enhanced.
  • the non-wood lignocellulosic biomass comprises biomass originating from plants of the Order Poales, the Order Solanales, the Order Arecales, the Order Malphighiales, the Order of Rosales, the Order of Malvales and/or herbaceous plants.

  • nature grass provides good results when manufacturing packaging units such as egg packages.
  • nature grass may originate from
  • This family of plants has shown good manufacturing possibilities in combination with providing a sustainable product to the consumer.
  • the packaging unit comprises one or more reinforcement elements configured to increase stability of the packaging unit.
  • reinforcement elements such as ribs, grooves, protrusions, etc. improves the mechanical properties including strength, stability, tensile strength, three-point bending stiffness and compression etc. This enables the use of a higher amount of non-wood lignocellulosic biomass. More specifically, this enables the use of an amount above 80 wt. %, more preferably above 85 wt. % is possible. Preferably, the use of reinforcement elements allows for the use an amount above 92.5 wt. %. This provides a sustainable packaging unit with a natural feel and has good mechanical properties both in the manufacturing process and its actual use.
  • the reinforcement elements comprise a number of ribs extending over at least a front surface of the bottom part. This rib or these ribs strengthen the front surface of the bottom part. This improves the manufacturing process and the strength of the packaging unit according to the invention in use.

  • lignocellulosic biomass or even a higher amount of non-wood lignocellulosic biomass, on dry fibre weight enables to manufacturing a moulded fibre food packaging in a an environmental friendly way without compromising too much on strength of the package.
  • using lignocellulosic biomass not originating from wood as raw material for the fibre pulp mix results in the manufacturing process becoming less independent of wood fibres. This is relevant when paper as journals will become less available what will lead to higher prices of paper in the future.
  • the lignocellulosic biomass originates from grass type plants.
  • the grass originates preferably from controlled cultivation such that regulation in connection with food contact may be respected with more ease. More preferably this controlled cultivation does not involve fertilizing. It is conceivable to use other grass as well like roadside grass for non food packages. It will be understood that the invention is not limited to grass fibres including other gramineous plants. It is conceivable that other natural fibres, other than wood, like straw fibres, sugar beet residue, are used in the invention.
  • the method comprises, before adding the lignocellulosic biomass to the pulp mix in a pulp container, processing the lignocellulosic biomass for removing protein from the lignocellulosic biomass such that the lignocellulosic biomass preferably contains between 0 to 2% protein in dry weight.

  • the method comprises pre-processing of the lignocellulosic biomass, the pre-processing comprising soaking the lignocellulosic biomass in water for a soaking period of at least 1 day preferably at least 2 days.
  • Pre-processing here means processing the lignocellulosic biomass before adding the lignocellulosic biomass to a pulp container with the pulp mix.
  • the pre-processing comprises cutting the lignocellulosic biomass, preferably before the soaking, for obtaining visible lignocellulosic biomass fibres having a length such that the visible lignocellulosic biomass fibres may surface on the fibre pulp mix, the visible lignocellulosic biomass fibres preferably having an average length smaller than 5 cm, preferably smaller than 2 cm, more preferably between 1.5 and 2 cm.
  • the visible lignocellulosic biomass fibres having a length such that the fibres may surface on the fibre pulp mix ensure that during moulding these relatively long fibres are positioned at a package surface. These long fibres are then visible on a package and can be distinguished by touch. This provides an improved appearance to the food package.
  • visible has its ordinary meaning that the fibre can be seen with the naked eye without any aid. It will therefore be understood that fibre does not refer to fibres on cellulose level. Instead a fibre here is on biomass level and may have a width typical between 0.1 mm to 2 mm.
  • the pre-processing comprises adjusting the degree of refining the visible lignocellulosic biomass fibres for facilitating firstly interaction between the fibre pulp and the visible lignocellulosic biomass fibre in the pulp mix, and secondly allowing a portion of the visible lignocellulosic biomass fibres to surface on the pulp mix. Because of the adjusting, an optimum can be chosen for both the strength of the package and the so called "green" appearance.
  • the pre-processing comprises providing a refining device comprising a number of refiner discs arranged at a mutual disc distance wherein adjusting the degree of refining the visible lignocellulosic biomass fibres comprises adjusting the disc distance less than 1.5 mm, preferably between 0.5 and 1.5 mm, and wherein the refining comprises refining the visible lignocellulosic biomass fibres at a concentration of between 10 kg to 75 kg, preferably about 25 kg visible lignocellulosic biomass fibres in dry weight, per 1000 litre of water.
  • a refiner is a Sprout Waldron disc refiner.
  • the refining comprising fibrillating the visible lignocellulosic biomass fibres for increasing binding surface of the visible lignocellulosic biomass fibres. This even more for facilitates interaction between the fibre pulp and the visible

  • Alternative reinforcing elements that may be applied in combination with grooves 38 comprise strengthening rods, rims and/or protrusions 44.
  • Groove 38 comprises side wall 46 ( Figure 8).
  • the method comprises pre-processing of the lignocellulosic biomass involving a number of steps. Depending on the product all steps are required or, alternatively only some steps need to be performed optionally with further steps. This pre-processing may be done on site or (partly) elsewhere. When the lignocellulosic biomass is pre-processed elsewhere, the lignocellulosic biomass fibres may be added directly to the pulp mix.
  • the pre-processing comprises soaking the lignocellulosic biomass in water for a soaking period of at least 1 day preferably at least 2 days.
  • the pre-processing comprises cutting the lignocellulosic biomass, preferably before the soaking, for obtaining visible lignocellulosic biomass fibres having a length such that the visible lignocellulosic biomass fibres may surface on the fibre pulp mix.
