When starch straws bid farewell to the human dining table, they are embarking on a more fantastical journey: transforming into high protein organisms in the belly of yellow mealworms and transforming into organic fertilizers under the wings of black soldier flies. No energy consumption, no secondary pollution, the master of decomposition in nature amplifies the value of straws by a hundred times.
1、 Why are insects obsessed with starch straws?
The deadly attraction of the ‘dual carbon feast’! The proportion of amylose in straws is greater than 70%, which is easier for insects to absorb than corn; The micropores generated by high-pressure molding accelerate the larvae’s gnawing efficiency by three times!
Operation process
1. Recycle straws → Cut scissors into 5mm pieces
2. Mixed substrate: straw debris 50%+wheat bran 30%+vegetable leaves 20%
3. Release yellow mealworms → 25 ℃ dark box feeding
4. Harvest in 7 days:
• Fat worms (feeding chickens/fishing)
• Insect sand fertilizer (vegetable cultivation tool)
2、 Economic Account: How can straw insect farming create a hundredfold value?
Product | Straw cost | Market value | Value added multiple
Yellow mealworm live | 0.3 yuan/kg | 18 yuan/kg | 60 times
Insect manure organic fertilizer | 0.1 yuan/kg | 8 yuan/kg | 80 times
Dried black soldier fly | 0.5 yuan/kg | 45 yuan/kg | 90 times
Comparison of incineration | Disposal fee of 300 yuan/ton | Pollution loss of 500 yuan/ton | Negative income
3、 Triple fission of ecological benefits
1. Carbon reduction engine: 1 ton of straw for insect farming=1.8 tons of CO ₂ reduction (equivalent to the annual carbon sequestration of 100 trees)
2. Protein replacement revolution: replacing fishmeal with insect protein → reducing wild fish catch by 3 tons per ton
3. Land rescue plan: replacing chemical fertilizers with insect manure → reducing pesticide use by 60% per acre of farmland.
