In order to remove the excessive nutrient salt at Port of Amagasaki, we have established the method to utilize the cycle of life: by cultivating seaweed at the port, removing shellfish from the upright sea walls, and turning them into compost. In cooperation with the local junior high school students, local citizens, experts, and administration, the junior high schools of Amagasaki provided the environmental study through this activity, based on the theme of “Cycle of Life”. In this report, we describe about the effects of this study. 1) Before the study, a survey showed that most of the students had bad impression toward Amagasaki Sea, such as “dirty” and “smelly”. However, after the study, the impression turned into better impression such as “fun” and “more familiar”. 2) In the Technology class, the students successfully cultivated more than 50 kinds of vegetation. As the students cooked and ate the vegetables and fruits they grew, the study also developed into “Food Education”-learning the connection between their health, environment, and food. 3) The students cooked using the oil extracted from the seeds of rape blossoms cultivated with their compost. Then they watched waste oil being refined and turned into bio diesel fuel, which activated car engine. Through such experiences, many students realized the cycle of life as “the life continues in different forms”, and the respect for life as well as developing their awareness to improve the natural environment.

Solid acid catalyzed cracking of waste oil-derived fatty acids is an attractive route to hydrocarbon fuels. HZSM-5 is an effective acid catalyst for fatty acid cracking; however, its microporous nature is susceptible to rapid deactivation by coking. We report the synthesis and application of hierarchical HZSM-5 (h-HZSM-5) in which silanization of pre-crystallized zeolite seeds is employed to introduce mesoporosity during the aggregation of growing crystallites. The resulting h-HZSM-5 comprises a disordered array of fused 10–20 nm crystallites and mesopores with a mean diameter of 13 nm, which maintain the high surface area and acidity of a conventional HZSM-5. Mesopores increase the yield of diesel range hydrocarbons obtained from oleic acid deoxygenation from ~20% to 65%, attributed to improved acid site accessibility within the hierarchical network.

Cooking Oil

Biofuels have received considerable attention as a more sustainable solution for heating applications. Used vegetable oil, normally considered a waste product, has been suggested as a possible candidate. Herein we perform a life cycle assessment to determine the environmental impact of using waste vegetable oil as a fuel. We present a cradle to fuel model that includes the following unit processes: soybean farming, soy oil refining, the cooking process, cleaning/drying waste oil, preheating the oil in a centralized heating facility and transportation when required. For soybean farming, national historical data for yields, energy required for machinery, fertilizers (nitrogen, phosphorous and potassium), herbicides, pesticides and nitrous oxide production are considered. In soy oil refining, steam production using natural gas and electricity for machinery are considered inputs. Preprocessing, extraction using hexane and post processing are considered. In order to determine a mass balance for the cooking operation, oil carryout and waste oil removal are estimated. During waste oil processing, oil is filtered and water removed. Data from GREET is used to compute global warming potential (GWP) and energy consumption in terms of cumulative energy demand (CED). Mass allocation is applied to the soy meal produced in refining and oil utilized for cooking. Results are discussed with emphasis on improving sustainability. A comparison is made to traditional fuels, e.g., commercial fuel oil and natural gas. The production of WVO as fuel has significantly less global warming potential but higher cumulative energy consumption than traditional fuels. The study should provide useful information on the sustainability of using waste cooking oil as a fuel for heating.
