Application Of Agricultural Waste Biochar For Canteen Wastewater Treatment In Chulalongkorn University, Norakamon Ariyakanon, Chalisa Vikrompanitkul

The International Student Science Fair 2018

The potential use of biochar in canteen wastewater remediation. Biochars were prepared from rice straw, bagasse or coir, produced by slow temperature pyrolysis at 300oC for 1 h. This study characterized the physical and chemical properties of biochar products related to wastewater treatment. The physical and chemical parameters of wastewater were analyzed before and after treatment with the three different types of biochar. Measured parameters included, pH, biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), oil and grease, total phosphorus (TP) and total nitrogen (TKN). The biochar derived from rice straw contained the highest …

Sustainable Agriculture: Integration Of Aquaponics At Punta Leona Hotel And Club In Costa Rica, Cailin Sierra Dyer, Paris Riley Smith

Senior Honors Projects, 2010-2019

Sustainable agriculture is becoming an increasingly important method of food production. As human populations continue to grow, attendant food demand has been increasingly met via agribusiness, including monoculture crop production and factory farming. As is well documented, the rise of agribusiness has led to resource degradation and declining stocks on which “sustainable agriculture” relies. This paper describes a local attempt to re-establish “sustainable agriculture” through the development of an aquaculture system that mimics a naturally occurring cycle that integrates fish and plants. The system was constructed over a three-week period in Punta Leona, Costa Rica. First, the ground was cleared …
