Claim Text:
1. A novel process for preparing special refuse biodegradable bag ties comprising a) collecting natural plant products for said biodegradable bag ties comprising fronds, husks, and leaves of corn, lemon grass, palm, cabbage, rice, coconut, lettuce, artichoke, aloe, cactus, or bamboo, and cutting said natural plant products into plant strips of, 1-3 inches wide by 7-14 inches long; b) pretreating said plant strips by incubation at 80 degrees centigrade for 15-60 minutes in a dilute aqueous alkali solution comprising sodium hydroxide, ammonia, or sodium acetate or a dilute aqueous acidic solution comprising sulfuric acid, acetic acid, hydrochloric acid or trifluoroacetic acid, or a dilute aqueous solution of cellulase, cellobiohydrolase, endoglucanase, xylanase, pectinase, cellobiase, or hemicellulase at 37 degrees centigrade, or a dilute aqueous suspension of glycolytic fungi or bacteria for 5-90 minutes at 23-27 degrees centigrade to provide pretreated plant strips; c) treating said pretreated plant strips with microwave radiation in water for 5-30 minutes at 50-500 watts following the previous chemical or enzymatic step, or combined with step 1b above without heating to form tie materials; d) impregnating, said tie material with inorganic peroxide by lightly spraying a 0.01-0.1% aqueous solution of strontium peroxide, calcium peroxide, magnesium peroxide, barium peroxide with sodium chlorate, hydrogen peroxide combined with an ester of pyrocarbonic acid or an N-vinyl heterocylic, lithium peroxide, sodium peroxide, sodium peroxyborate monohydrate, or sodium carbonate peroxyhydrate, and air-dying for 12 hours at 23-27 degrees centigrade; e) applying a 2-3 inch long strip of double-side adhesive tape to an end portion of said tie materials, and retaining a release tape backing to form said biodegradable bag ties.
