Abstract

The invention provides a biodegradable and/or compostable pulp composition, moulded pulp article(s) and preparation process thereof. In particular, the biodegradable and/or compostable pulp composition comprises an exogenous protease, e.g. papain and the moulded pulp article(s) are impregnated with the exogeneous protease. The impregnated protease assists in breaking down the moulded pulp article(s) and thus enhances the rate of decomposition. The moulded pulp article(s) according to the invention may be composted within 45 to 180 days. The biodegradable and/or compostable pulp composition may also be composted. The compost obtained may be used as fertilisers. The biodegradable and/or compostable pulp composition and/or the moulded pulp article may also be used as animal feed.
