چکیده
زمینه و هدف: چای به‌عنوان یکی از پرمصرف‌ترین نوشیدنی‌های جهان، حجم قابل توجهی از ضایعات تولید می‌کند که اغلب بدون بهره‌برداری مناسب دفع می‌شوند. با افزایش تولید جهانی چای، مدیریت این ضایعات به یک چالش زیست‌محیطی مهم تبدیل شده است. هدف از این مطالعه، ارائه‌ی یک مرور جامع بر نوآوری‌ها در استفاده از ضایعات چای و بررسی پتانسیل‌های ارزش‌افزایی آن‌ها در حوزه‌های مختلف است.

مواد و روش‌ها: این مطالعه به‌صورت یک مقاله مروری نقلی انجام شد که در آن، پژوهش‌های منتشرشده در زمینه ضایعات چای با تمرکز بر فناوری‌های فرآوری، روش‌های تبدیل و کاربردهای نوین آن‌ها ازجمله تولید بیوچار، تولید سوخت‌های زیستی، تولید بیوگاز و بیوپلاستیک، ابرخازن‌ها، آئروژل‌ها و هیدروژل‌ها و نانومواد کامپوزیتی مورد بررسی قرار گرفت.

یافته‌ها: نتایج بررسی‌ها نشان داد که ضایعات چای دارای پتانسیل بالایی برای تولید محصولات با ارزش افزوده ازجمله ترکیبات زیست‌فعال، جاذب‌های زیستی و منابع انرژی تجدیدپذیر هستند. هم‌چنین، به‌کارگیری رویکردهای نوآورانه در فرآوری این ضایعات می‌تواند نقش مؤثری در کاهش پسماند، بهبود مدیریت منابع و توسعه کاربردهای آن‌ها در بخش‌های گیاهی، حیوانی و زیست‌محیطی ایفا کند.

نتیجه‌گیری: استفاده جامع و پایدار از ضایعات چای در چارچوب اصول اقتصاد چرخشی و رویکرد «بدون زباله»، می‌تواند به‌عنوان راهکاری مؤثر برای کاهش اثرات زیست‌محیطی، افزایش بهره‌وری اقتصادی و جایگزینی مناسب برای منابع زیست‌توده متداول مطرح شود. این مطالعه با ارائه‌ی دیدگاهی یکپارچه، می‌تواند به توسعه‌ی تحقیقات آینده و تصمیم‌گیری‌های علمی و صنعتی در زمینه‌ی بهره‌برداری پایدار از ضایعات چای کمک کند.

چکیده English

Background and Objective: As one of the most widely consumed beverages globally, tea generates a significant volume of waste, often disposed of without proper utilization. With increasing global tea production, managing this waste has become a critical environmental challenge. The aim of this study is to provide a comprehensive review of innovations in tea waste utilization and explore its value-added potentials in various fields.


Materials and Methods: This study was conducted as a narrative review, examining published research on tea waste, focusing on processing technologies, conversion methods, and novel applications. These applications include the production of biochar, biofuels, biogas, bioplastics, supercapacitors, aerogels, hydrogels, and composite nanomaterials.


Results: The findings indicate that tea waste has a high potential for producing value-added products of bioactive compounds, biosorbents, and receptive energy sources. Also, innovative applications in processing these wastes can play an effective role in reducing waste, improving resource management, and developing their applications in the plant, animal, and environmental sectors.


Conclusion: Comprehensive and sustainable use of tea wastes, in regulating the principles of circular economy and non-consumption environment, can be used as a solution for environmental reduction, economic efficiency, and a suitable replacement for conventional biomass resources. By providing an integrated perspective, this study can help develop scientific and industrial research and decision-making in the field of sustainable utilization of tea wastes.
