Progress & outcomes

Strategy for Organic Waste Diversion - Collection, Treatment, Recycling and Their Challenges and Opportunities for the City of Sao Paulo, Brazil

The Waste Initiative partner and implementer, ISWA, helped the city to formulate a strategy for organic waste diversion with the aim of reaching the goals in the City’s MSW Master Plan 2014. In addition, the strategy includes technical guidance on the operation of organic waste treatment plants, such as composting, anaerobic digestion and MBT plants. The technical guidance was prepared by ISWA’s senior experts with the assistance of a local waste management expert to ensure that the existing legal framework was included.

Technical Guidance on the Operation of Organic Waste Treatment Plants

The document is aimed at providing technical guidelines to local authorities, plant suppliers and plant managers in order to help them manage the organic waste fraction in a proper way both from a processing as well as from an environmental protection point of view. Information will be given on how to make proper choices on waste acceptance and treatment in such a way that it leads to an optimized transformation and the derivation of a product suitable for being utilized as an organic fertilizer in the case of organic waste from separate collection or a safe residue for final disposal with possible recovery of materials (in the case of residual waste). For each type of plant, indications will be given on possible layouts, mass balances and building and managing approaches aimed at minimizing environmental impacts on the surroundings of the installation and the health of workers.

Enhance Organic Waste Management in Schools and Awareness of Teachers and Children

ISWA, a partner of the Waste Initiative, organized a meeting with school representatives and city officials to find ways to enhance organic waste management in schools and the awareness of teachers and children. During this meeting, it was decided that the best way to meet the objective was to establish a feedback and communication platform via online social networks. The platform would facilitate dialogues among schools. The platform would also serve as a tool to collect information for a handbook on the management of organic waste, including the other fractions (dry and residual waste), for school education.

ISWA led the writing of the handbook in close collaboration with the local consultant managing the school communication platform.

Evaluation and Recommendation Report of the Pilot Composting Plant in the Lapa District of the City of Sao Paulo

ISWA, a partner of the Waste Initiative, assisted the City of Sao Paulo in the planning phase and implementation phase of a small-scale composting plant, by evaluating the existing plan. This first composting plant will treat public garden and park green waste and organic waste from street markets. An evaluation and recommendation report was provided to the city.

Implementation Plan for a Trial for Separate Collection of the Organic Fraction of Household Waste in the Lapa District in Sao Paulo

With the overarching work plan for diversion of organic waste laid out in the strategy paper, ISWA designed a trial for separate collection of household organic waste from a selected area (maximum 5,000 inhabitants) in the Lapa District (City of Sao Paulo) and developed a roll-out/implementation plan.

Environmental Communication Strategy for MSW Management in Sao Paulo, Brazil

ISWA, a Waste Initiative partner, developed a communication strategy with key stakeholders, which identifies the goals, target groups, communication measures for the different target groups, taken into consideration the evaluation of existing communication methods. 

Training Workshops for Capacity Building and Knowledge Transfer on Organic Waste Management
