    ZAAO Projects

    Project launch 2022

    ZAAO will assess how to offer this service more efficiently to customers, whether they understand what kind of waste can be placed in the BIO waste container, what would be the most appropriate frequency for emptying the containers, etc. The pilot project is scheduled to run until 30 December 2023. The pilot project will be implemented in the Leona Paegles iela block of Cēsis and in the streets adjacent to the block.

    Project launch 2022

    Climate change is about to become a climate crisis and the project “Re:waste – how Sweden is rethinking resources” shares experiences and solutions on how we can collectively avoid climate change by engaging businesses, governments and consumers.

    Project launch 2022

    Improve the implementation of Structural Funds in waste management and improve regional and inter-regional ecosystems.

    Project launch 2022

    Promote regional sustainability and circularity by introducing waste as a resource concept.

    Project launch 2021 | Funding 8 540 675.04 EUR

    Establishment of a Biodegradable Waste Treatment Plant (BWTP), reducing the amount of biodegradable waste to be disposed of, thereby increasing the efficiency of waste utilisation.

    Project launch 2015 | Funding 483 129 EUR

    Establishment of a Biodegradable Waste Treatment Plant (BWTP), reducing the amount of biodegradable waste to be disposed of, thereby increasing the efficiency of waste utilisation.

    Project launch 2022 | Total budget:of the project 4 284 280,00 EUR

    The H2Value project aims to create the first inter-regional green hydrogen value chain in Southern Estonia (Tartu region) and Northern Latvia (Vidzeme region), thus contributing to the EU climate targets and the transition to a green economy.

    Project launch 2020 | Total budget:of the project 195 252,62 EUR

    The main objective of the project is to expand the knowledge base on carbon capture and storage (CCS) technologies for municipal solid waste (MSW) in an approach that integrates CCS into the “energy from waste” concept. The project therefore aims to develop the capture and storage of carbon dioxide from municipal waste recycling (the so-called CCSW- Carbon Capture and Storage from Waste).
