Canadian blueberry leaves (Vaccinium corymbosum) are a potential source of polyphenols (catechins) and antioxidants (FRAP and PT). In this study, the technique of drying by microwave-assisted forced convection was carried out to find the optimal conditions which would allow obtaining the highest polyphenol content under control parameters such as microwave power (100, 300, and 400 W), hot air velocity (0.5 and 2.0 m/s), leaf size (whole and fractional), and temperatures (50, 60, and 70°C). It was found that 30 W/g microwave powers and a 60°C temperature for the process in whole leaves were the optimal conditions that allowed obtaining the highest content of polyphenols (>10 mg/gdb (+) catechin) and antioxidant capacities (100-150 mg GAE/gdb), more than in fractional leaves. It was observed that different hot air velocities did not affect the concentration of the polyphenol's contents; this was verified using the factor mixture analysis technique. Practical applicationsThe MWFC process allows the preservation of antioxidants in Canadian blueberry leaves (Vaccinium corymbosum). These leaves have high antioxidant capacity for nutraceutical and pharmaceutical uses. This leaf, with high polyphenol content, can be used to obtain extracts in infusions and human food through the mixture of this leaf with multiple powdered products traditionally consumed or food supplements. This research presents the optimal conditions for the preservation of antioxidant compounds in dried Canadian blueberry leaves. Highlights• Polyphenolic compounds (catechins) are retained under controlled conditions of microwave drying assisted by forced convection in Canadian blueberry leaves.

Recycling Temple Waste into Organic Incense as Temple Environment Preservation in Bali Island

Kegiatan upacara di tempat suci pura di Pulau Bali rata-rata menghasilkan sampah sekitar 2000 L/hari. Sebagai bagian yang sangat penting dari budaya Bali, sesajen yang terdiri dari bunga, daun, buah-buahan dan bambu disajikan di setiap upacara keagamaan. Pembuangan sampah pura yang tidak tepat berpotensi menimbulkan gangguan pada kehidupan manusia dan lingkungan, seperti air dan sanitasi, penumpukan sampah, peningkatan tingkat pencemaran, dan kesehatan manusia. Penelitian ini bertujuan untuk mendaur ulang sampah pura, khususnya sisa bunga menjadi dupa organik serta mengkaji alternatif lain dalam daur ulang sampah pura. Daur ulang sisa bunga menjadi dupa organik dilakukan dengan menggunakan tiga bahan campuran. Kajian literatur digunakan untuk menambah informasi alternatif daur ulang sampah pura dari penelitian sebelumnya. Hasil eksperimen menunjukan bahwa sampah sisa bunga dapat didaur ulang menjadi dupa organik. Rasio campuran 1:2 untuk sisa bunga dan bubuk esensial memberikan hasil terbaik. Dupa organik yang terbentuk sangat kuat dan padat. Selain itu, aroma campuran yang dihasilkan lebih baik di antara yang lain. Sampah pura juga dapat didaur ulang menjadi beberapa produk berharga, seperti kompos, ekstrak warna minyak atsiri, bubuk warna, atau biogas. Diestimasikan sebuah pura menghasilkan sekitar 200 kilogram sampah pura dalam satu hari upacara. Sekitar 40% dari sampah pura merupakan sisa bunga (berat basah) dengan kadar air sekitar 80%. Setelah melalui proses pengeringan, sisa bunga mencapai 16 kilogram. Diperkirakan sekitar 45 ton sampah pura dari 230 pura publik di Pulau Bali dapat didaur ulang setiap tahun melalui upaya daur ulang. Beberapa dampak yang ditimbulkan dari upaya daur ulang ini, seperti mengurangi sampah pura, menciptakan produk daur ulang yang dapat dipasarkan, dan meningkatkan keharmonisan antara budaya, lingkungan, dan masyarakat melalui pemberdayaan masyarakat. ABSTRACTCeremonial’s activities in Bali’s Temple have produced about 2000 L/day of waste in average. As an integral part of Balinese culture, devotion offerings which consists of flowers, leaves, fruits and bamboo are presented at every ceremony. The improper disposal of temple waste potentially causes a stress on the basic services in human life, such as water and sanitation, waste accumulation, raising the level of pollution, and human health. The present study aims to leverage of temple waste, especially discarded flower into organic incense through recycling and find out the foreseen impact of this initiative to the environment. Processing discarded flower into organic incense was conducted in this research with three material mixtures ratio. A literature review was added to enhance the alternatives of discarded flowers recycling on previous research. It is found that discarded flower was successfully recycled into organic incense. The preliminary experiments showed that the ratio of 1:2 for discarded flowers and essential powder gave the best results. The incenses were very strong formed and solid. Additionally, the smell of best mixture was the best among others. Besides, temple waste can be recycled to some valuable products, such as vermicompost, dyes extraction, essential oil, color powder, or biogas. It assumed that a temple has produced around 200 kilograms of temple waste during a ceremonial day. About 40% of those was discarded flowers (wet weight) that 80% contains water. After the drying process, it has left 16 kilograms of dried discarded flowers. It estimated around 45 tons of discarded flowers from 230 public temples around Bali could be recycled every year through this recycling effort. Some impacts come up with following this initiative, such as reducing the temple waste, creating a marketable recycling product, and build up a harmony between the cultural, environment, and society through community empowerment.

“…The woody part of flower waste can be converted into biochar through the process of slow pyrolysis (Bogale, 2017). Biochar can be further used as a material for absorption or adsorption of heavy metals and other harmful substances resulting in purification of wastewater (Waghmode et al, 2018).…”

Environmental Degradation: Causes and Remediation Strategies

View full text Add to dashboard Cite

Today, environmental degradation is the utmost problem leading to the extinction of several living organisms on the earth. Environmental degradation can be seen in the form of lost living forms due to disturbances in the earth's ecosystem. The recent developments in human civilization are the major reason for the degradation of the environment and its quality. This edited book is the compliance of selected reports destined to provide information regarding causes, effects and mitigation strategies of environmental degradation.The compliance of this book is helpful for academicians, researchers, students, as well as other people seeking the relevant material in current trends of studies on the topic of environmental degradation. The book starts with an introductory chapter providing background information on the topic covering the necessity of the mitigation measures to be taken in order to ensure the conservation of our mother earth. The second chapter discussed the role of disasters leading to the degradation of environmental composition. The role of pesticides in the degradation of agricultural quality is discussed in the third chapter. Special attention is given to the degradation of river systems with reference to exhausting its resources. The book compliance includes many chapters focusing on environmental degradation by wastewater disposal practices. Certain mitigative measures are provided focusing on sustainable utilization of wastewater for agricultural and horticultural applications. The second half of the book includes sustainable utilization of various solid wastes such as spent mushroom compost, flower wastes, wood wastes, non-conventional plant residues, etc. which may cause deterioration of our environment. The last section of the book provides information regarding the impacts of environmental degradation on biodiversity as well as human economics including agriculture.Lastly, the editors are thankful to the contributors who submitted their precious findings and views related to the book theme and to make it succeeded. We hope that this book will help the readers in its best to provide them the relevant information.
