Abstract
The invention provides a method of converting livestock feed waste to biological plastic. The method comprises the following steps: adding inorganic nutrients and fungal spores into the livestock waste; adding into a die; cultivating and breeding in a proper condition; and after the hypha fills the die, roasting and setting the die to obtain the biological plastic. The method provided by the invention on the one hand solves pollution of chemical synthetic plastic and on the other hand solves the problems that the cost of preparing other biological plastics is high and the like because the source the raw materials is environmentally friendly and low in cost.
Description
Technical field
The present invention relates to refuse reuse field, refer to especially a kind of method that livestock rearing waste material is converted into biological plastics.
Background technology
Xylonite goods, bring the various whiles easily to the mankind, also bring unthinkable trouble to people, and because some waste plastic is non-degradable under field conditions (factors), burning can discharge obnoxious flavour again, have caused the pollution that is difficult to improvement to ecotope.Whole world scientist is being devoted to exploitation " new bio plastics " at present, this plastics be take the crude substance such as starch as basic synthetic under microbial process, therefore except possessing all convenient purposes of Xylonite, had more the reproducible advantage of degradable standby.Yet still non-perfection of this new bio plastics; first biological plastics present stage is higher two or three times than common plastics price; hindered the universal rapidly of this class material; secondly the raw material sources of this kind of plastics are in food crop; once put into production in a large number, will inevitably increase the weight of crisis in food; it is also finally raw material problems; dispute due to genetically modified crops; the Biosafety problem of this plastics also has to consider; therefore, be badly in need of the lower plastics of a kind of environmental protection while production cost and substitute two kinds of above-mentioned plastics.
Summary of the invention
The present invention proposes a kind of method that livestock rearing waste material is converted into biological plastics, has solved the pollution that can cause due to conventional plastic in prior art, and new bio plastics are with high costs, increases the weight of the problem of crisis in food etc. simultaneously.
Technical scheme of the present invention is achieved in that a kind of method that livestock rearing waste material is converted into biological plastics, comprises the following steps:
1., herding argol is mixed according to the ratio of 1:1 ~ 1:10 with the careless slag drying, cereal shell, stalk, cotton slag after just smashing, then add mineral nutrition thing, by unslaked lime, regulate pH value scope 7 ~ 8, fully mixing, obtains mix;
2. after, described mix is carried out to high-temperature sterilization, cooling, make water content be controlled at 60% ~ 80%;
3., the cooled described mix of sterilizing is fully mixed with fungal spore, obtain cultivating breeding mixture;
4., described cultivation breeding mixture put into mould cultivate, and maintain the required external environmental condition of microorganism growth;
5., cultivate and to have bred after, described mould is put into baking box and toasts, according to circumstances, also can say that mould opens, directly thalline is put into baking box and toasts, design temperature, at 60 ℃ ~ 120 ℃, toasts 3 ~ 5 hours, obtains finished product.
Further, step 3. described in fungal spore be straw mushroom spore, described straw mushroom spore mixes with 20 ~ 30KG mix according to the straw mushroom spore of a 750ML seed bottle with described mix.
Further, when step 3. described in fungal spore while being straw mushroom spore, the described mineral nutrition thing that step adds in is 1., account for the bicarbonate of ammonia of described mix gross weight 0.2% ~ 0.6% and account for the dipotassium hydrogen phosphate of described mix gross weight 1% ~ 3%, described pH value is 7.5 ~ 8, step 4. described in external environmental condition be, temperature is 32 ℃ ~ 37 ℃, humidity is 70% ~ 90%, keeps dark and ventilates, and 5. step was cultivated and bred through 10 ~ 15 days.
Further, step 3. described in fungal spore be bisporous mushroom spore, described bisporous mushroom spore mixes with 10 ~ 20KG mix according to the straw mushroom spore of a 750ML seed bottle with described mix.
Further, when step 3. described in fungal spore while being bisporous mushroom spore, step 1. in, described herding argol mixes according to the ratio of 1:2 ~ 1:5 with the described careless slag drying, described cereal shell, described stalk etc. after just smashing, the described mineral nutrition thing adding is, account for the calcium superphosphate of described mix gross weight 0.1% ~ 0.5%, step 2. middle water content is controlled at 60% ~ 70%, step 4. described in external environmental condition be, temperature is 22 ℃ ~ 25 ℃, humidity is 70% ~ 80%, keeps dark and ventilates, and 5. step was cultivated and bred through 10 ~ 15 days.
Further, step 3. described in fungal spore be flat mushroom spore, described bisporous mushroom spore mixes with 10 ~ 20KG mix according to the straw mushroom spore of a 750ML seed bottle with described mix.
Further, when step 3. described in fungal spore while being flat mushroom spore, step 1. in, described herding argol is just smashed the rear described careless slag with drying, described cereal shell, described stalk and described cotton slag etc. mix according to the ratio of 1:1 ~ 1:5, the described mineral nutrition thing adding is, account for the bicarbonate of ammonia of described mix gross weight 0.3%, account for the potassium primary phosphate and the light calcium carbonate that accounts for described mix gross weight 2% of described mix gross weight 2%, described pH value is 7.5 ~ 8, step 2. middle water content is controlled at 65% ~ 70%, step 4. described in external environmental condition be, temperature is 24 ℃ ~ 28 ℃, humidity is 70% ~ 80%, keeping dark ventilates, 5. step was cultivated and has been bred through 20 ~ 25 days.
Beneficial effect of the present invention is: the present invention is by adopting herding waste material, comprise the argol of herding just, hay, stalk, cereal shell, wood chip, waste cotton slag etc., it is cultivated together with described fungal spore, and add corresponding described mineral nutrition thing, the described fungal spore required envrionment conditions of growing is provided, be encased in and in described mould, carried out growth and breeding, through after a period of time, mycelia is covered with described mould, now, mould is put into baking box and toast setting, obtain finished product, because the starting material that adopt are herding waste material and a small amount of inorganic salt etc., with low cost, and described finished product is mainly the housing of mycelia, there is degradability, the feature of environmental protection, because have through high-order sterilisation step and high bake step in the process of preparation, sanitation performance to finished product provides assurance.
