Definitions

  • pulp formed plant pots should be formed of only of materials which are a benefit to the ground, or to the growing medium to be used in the plant pot.
  • Known materials for pulp formed plant pots / cell trays include wastepaper and cardboard; these materials are also used in other pulp forming applications such as egg trays and cartons, and general industrial packaging.
  • wastepaper and cardboard as a growing medium is in question.
  • the at least one aggregate may comprise at least one of lightweight expanded clay aggregate, terracotta, perlite, vermiculite, and pumice.
  • the at least one fibrous material comprise may cotton grass root fibres, and wastepaper or cardboard fibres, and the aggregate comprises lightweight expanded clay aggregate.
  • the composition may comprise an equal proportion by weight of the cotton grass root fibres, the wastepaper or cardboard fibres, and the aggregate.
  • the present invention comprises a method of mould forming a plant container, the method comprising steps of; a) mixing together at least one biodegradable fibrous material, at least one aggregate formed of a lightweight, natural, inorganic, and absorbent material, and a biodegradable binding agent, to form a mixture; b) pulping the mixture to form a pulp; c) dipping at least one platen comprising a plurality of moulds into the pulp; d) vacuuming the pulp into the plurality of moulds, to form a plurality of wet moulded plant containers; e) drying the plurality of wet moulded plant containers, to form a plurality of formed plant containers; and f) removing formed plant containers from the moulds.
  • Drying the formed plant containers comprises passing the plant containers through a drying tunnel or air drying the plant containers.
  • the fibrous material may be a cotton grass root fibre
  • the method may comprise a preceding step of obtaining the cotton grass root fibre as a by-product of a peat extraction process, or by natural harvesting.
  • the method may further comprising a step of, prior to step mixing, sieving and/or grading particles of the aggregate.
  • the present invention comprises a plant container formed by a method as described above.
  • Figure 1 is a front view of a plant pot in accordance with the present invention.
  • Figure 2 is a schematic representation of a fibrous material of a composition in accordance with the present invention.
  • Figure 3 is a schematic representation of an aggregate of a composition in accordance with the present invention.
  • the cotton grass root 120 consists of organic biodegradable long fibres 122, which provide a plant pot, once formed, with an acceptable strength, durability and longevity.
  • method of manufacture of a plant receptacle or container comprises steps of mixing together the at least one biodegradable fibrous material, the at least one aggregate formed of a lightweight, natural, inorganic, and absorbent material, and a the biodegradable binding agent, to form a mixture.
  • the mixture is then pulped.
  • At least one platen, comprising a plurality of moulds is then dipped into the pulp, and the pulp is then vacuumed into the plurality of moulds, to form a plurality of wet moulded plant containers.
  • the wet moulded plant containers are then dried, for example by being passed through a drying tunnel, or by allowing to air dry. A plurality of dry, formed plant containers are removed from the moulds.
  • the material composition of the present invention is compatible with conventional pulp forming machinery.
  • the illustrated embodiments are not limiting.
  • the material composition of the present invention is of particular use in the horticultural industry for transplantable plant containers, however it could be used to form any containers or other product formed by a pulp moulding process.
