Korzystnie, udziały poszczególnych frakcji w wytłokach wynoszą dla poszczególnych wielkości ziaren: 212 µm - 1 mm 35%, do 500 µm 50%, do 1,7 mm 15%. Korzystnie, gdy w kroku wybrane frakcje wytłoków z lnianki poddaje się działaniu wodą o temp. 80°C i suszy w temp. 100°C±50°C. Zgłoszenie obejmuje także biodegradowalne materiały stanowiące osłonki na cebule kwiatowe, bulwy lub kłącza, które mają postać pojemnika, tacki kształtki o wymiarach i kształcie dopasowanym do pakowanych w nich cebul, bulw lub kłączy, tj. o kształcie sferycznym, prostopadłościennym, eliptycznym lub walcowatym, wykonane są wytłoków z lnianki, zmieszanych z biotworzywami, korzystnie ze skrobią termoplastyczną, octanem celulozy, poli(alkoholem winylowym) i/lub z dodatkami niezbędnymi do uzyskania pożądanych cech użytkowych wyrobu końcowego typu plastyfikatory oraz z humektantami, takimi jak - mocznik, glicerol, sorbitol w ilości od 5% do 50% wagowych w stosunku do masy wybranego biotworzywa i/lub substancjami przeciwdrobnoustrojowymi pochodzenia naturalnego - ziołowe ekstrakty np.: ekstrakt z tymianku, majeranku, cebuli, czosnku, kurkumy, imbiru, które są podatne na rozpad w procesie biodegradacji, bezpieczne dla środowiska naturalnego oraz wspomagające wegetację, w ilości od 0,5% do 20% wagowych w stosunku do masy lnianki i są korzystnie pokryte poprzez natrysk warstwą z biotworzywami, korzystnie poli(alkoholem winylowym) lub poli(alkoholem winylowym) z udziałem substancji przeciwdrobnoustrojowych, a następnie suszenie.The subject of the application is a method for producing biodegradable casings for flower bulbs, which comprises the following steps: a) preparation of camelina pomace, i.e. crushing and fractionating the pomace and sieving it, as well as unifying its moisture content by treating it with water in the temperature range of 30°C-100°C and/or superheated steam or drying, b) preparation of a biodegradable material based on camelina pomace by combining the pomace with bioplastics, preferably with thermoplastic starch, cellulose acetate, polyvinyl alcohol and/or with additives necessary to obtain the desired functional properties of the final product, such as plasticizers, c) and/or humectants - urea, glycerol, sorbitol in an amount of 5% to 50% by weight in relation to the weight of the selected bioplastic and/or antimicrobial substances of natural origin - herbal extracts, e.g. from thyme, marjoram, onion, garlic, turmeric, ginger, which are susceptible to decomposition in the biodegradation process, safe for the natural environment and supporting vegetation, in an amount from 0.5% to 20% by weight in relation to the weight of the camelina, in particular the mixture of antimicrobial substances is composed of thyme extracts in an amount of 1% in relation to the weight of the casing before drying, marjoram in an amount of 3% in relation to the weight of the casing before drying, onion in an amount of 2% in relation to the weight of the casing before drying, garlic in an amount of 5% in relation to the weight of the casing before drying, turmeric in an amount of 5% in relation to the weight of the casing before drying and ginger in an amount of 4% in relation to the weight of the casing before drying, d) forming casings into a shape that facilitates planting bulbs, tubers or rhizomes to the appropriate depth in the ground and at a specific spacing by pressing under conditions of a specific temperature and pressure, e) and/or spraying previously formed shapes with bioplastics, preferably poly(vinyl alcohol) or poly(vinyl alcohol) with the participation of antimicrobial substances or mixtures thereof in an amount of 0.5% to 20% by weight in relation to the weight of the camelina, and then drying, wherein the raw material used is camelina pomace with a grain fraction in the range from 212 µm inclusive, to a size below 1.7 mm, of which the share of these fractions in the camelina pomace is 85%-95%. Preferably, the shares of the individual fractions in the pomace are for the individual grain sizes: 212 µm - 1 mm 35%, up to 500 µm 50%, up to 1.7 mm 15%. It is advantageous when in step 1 the selected fractions of camelina pomace are treated with water at a temperature of 80°C and dried at a temperature of 100°C±50°C. The application also covers biodegradable materials constituting casings for flower bulbs, tubers or rhizomes, which have the form of a container, tray, shaped part with dimensions and shape adapted to the bulbs, tubers or rhizomes packed in them, i.e. with a spherical, cuboidal, elliptical or cylindrical shape, made of camelina pomace, mixed with bioplastics, preferably with thermoplastic starch, cellulose acetate, poly(vinyl alcohol) and/or with additives necessary to obtain the desired functional properties of the final product, such as plasticizers and with humectants such as - urea, glycerol, sorbitol in an amount of 5% to 50% by weight in relation to the weight of the selected bioplastic and/or antimicrobial substances of natural origin - herbal extracts, e.g.: extract of thyme, marjoram, onion, garlic, turmeric, ginger, which are susceptible to decomposition in the biodegradation process, safe for the natural environment and support vegetation, in an amount of 0.5% to 20% by weight in relation to the weight of the camelina and are preferably coated by spraying with a layer of bioplastics, preferably poly(vinyl alcohol) or poly(vinyl alcohol) with the participation of antimicrobial substances, and then drying.
