Peter William Bonfield, Codicote GB
| Patent application number | Description | Published |
|---|---|---|
| 20090169812 | Process for Making Composite Products from Fibrous Waste Material - A process for making composite products from waste material comprises the steps of a) obtaining fibrous material produced by the thermal treatment of waste materials with pressurised steam; b) mixing the fibrous material with a binding material; c) forming the resulting mixture into a shape; d) pressing the shaped mixture under pressure; and e) hardening the mixture; wherein the process also comprises the steps of the separating out the fibrous material and deodorising the fibrous material. The waste material may be domestic bin liner waste. | 07-02-2009 |
| 20090233104 | Process for Making Composite Products - A process for making composite products such as doors comprises the steps of: i) forming a mass of plant fibres; ii) coating the mass of plant fibres with at least one resin and at least one catalyst without agitating the mass of plant fibres; iii) compacting the coated mass of plant fibres; and iv) curing the compacted mass of plant fibres; wherein the process also comprises the step of drying the plant fibres either before and/or after step ii). | 09-17-2009 |
