The continuous increase in polluted areas across Ukraine has led to a range of ecological issues. In this context, the creation of a digital tool that draws public attention to the problem of waste anagement and motivates responsible environmental behaviour is both relevant and necessary. The use of blockchain technologies provides the opportunity to build a reliable application that ensures the integrity of data related to waste recycling. It also enables the creation of a transparent reward system based on utility tokens and NFTs. The integration of two blockchain ecosystems — Internet Computer Protocol (ICP) and Solana — demonstrates the strengths of both technologies in terms of decentralisation, user accessibility, and scalability. The ICP blockchain offers a unique environment for hosting complete web applications on decentralised nodes without relying on traditional centralised servers. Through its innovative reverse gas model, end users are not required to hold tokens to interact with the platform, as the computational costs are covered by the developer or organisation behind the application. This allows for a seamless and user-friendly experience, particularly for non-technical participants in the recycling initiative. Meanwhile, Solana adds flexibility for the development of smart contracts and fast transaction processing. By combining these two technologies, the article provides a comparative overview of different blockchain architectures and gas models, contributing to a deeper understanding of their practical implications. Additionally, the article presents a brief explanation of the integration between the ICP and Solana blockchains, including token-based interactions, NFT issuance, and synchronisation of environmental data. The development process is supported by deployment tools such as DFX (for ICP canister management) and the Anchor framework for Solana, ensuring an efficient and structured development workflow. Overall, the work highlights the reasoning behind the selected technological stack, outlines the key requirements for the platform, and explores its potential for future growth and scalability. The project exemplifies how modern decentralised technologies can be harnessed to promote sustainable development and environmental responsibility in Ukrainian society.У цій статті розглянуто принципи створення вебплатформи для підвищення екологічної свідомості у громадян України. Продемонстровано, як використання блокчейн-технологій надає можливість побудувати надійний додаток, який гарантує коректність даних, пов’язаних з переробленням, і дозволяє розробити прозору систему винагород за допомогою utility-токенів і NFT. У роботі детально розглянуто процес розроблення екологічно корисної ініціативи, враховуючи аргументацію обраних технологічних рішень, аналіз вимог до системи, а також масштабованість і перспективи створеного у результаті вебдодатка в майбутньому.ukекологіяблокчейнICPInternet IdentitySolanaпереробка сміттядецентралізаціястаттяecologyblockchainICPInternet IdentitySolanawaste recyclingdecentralisationArticle
