Maqolada raqamli sifat boshqaruvi, polikarboksilat superplastifikatori va o‘z-o‘zini tiklovchi biobeton texnologiyasini birlashtirgan B30 sinfdagi tovar betonini ishlab chiqarishning oltita texnologik varianti qiyosiy iqtisodiy baholangan. Tarkiblar mustahkamlikning haqiqiy o‘zgaruvchanligini hisobga olgan holda Bolomey–Skramtayev formulasi bo‘yicha tanlangan. 50 yillik davr uchun hayotiy sikl qiymati ISO 15686-5 metodologiyasi asosida 13 ta noaniq parametr bo‘yicha Monte-Karlo usulida (10 000 ta hisob) aniqlangan; sement narxlari O‘zbekiston respublika tovar-xomashyo birjasining 2024–2026-yillardagi ma’lumotlari bo‘yicha olingan. Shuningdek, CO₂ chiqindilari, uglerodning soya narxi ta’siri va TOPSIS usulida variantlarning integral reytingi baholangan. Mustahkamlik variatsiya koeffitsientini 13,5 dan 10 foizgacha pasaytirish xarajatlar va chiqindilarni bir vaqtda kamaytiradigan yagona chora ekani hamda hisoblarning 90 foizida eng kam hayotiy sikl qiymatini ta’minlashi aniqlangan. Biobeton hayotiy sikl qiymatining standart chetlanishini 61 foizga kamaytiradi, biroq ta’mirlash qiymati 1 m³ uchun 1,0 mln so‘mdan yuqori bo‘lgandagina foydali bo‘ladi. Korxonalar va davlat buyurtmachilari uchun tavsiyalar asoslab berilgan
