Agroecological Management

According to the National Political Law, solid waste was defined as collection, transport, transshipment, treatment and environmentally appropriate final disposal of solid waste and rejects.

For the State of São Paulo, as well as for the other Brazilian States, data on the management of afforestation residues are scarce and little publicized. Such waste usually comes from the following activities:

  • City Hall: Management of afforestation, through the pruning and removal of urban trees
  • Electricity concessionaire: Pruning of trees, in order to avoid damage to the wiring system and the electrical network.

  • Research shows that the use and recovery of pruning waste represent about 4% of the total and most of it is thrown into dumps, deposits and landfills, vacant lots. When there is some type of waste recovery, applications are focused on the production of organic compost, infrastructure

    (holes, kills donkeys, etc.), erosion control, ceramics, potteries, farms, making stakes, among other uses.

    Minimizing and valuing pruning waste means saving resources and fuel and, consequently, polluting gases, which will no longer be released by trucks that travel through cities and highways to access landfills.

    Integrated waste management:

    Proper waste management consists of developing integrated policies and plans with the aim of:

    • a) prevent their generation
    • b) obtain the maximum use of recycling materials
    • c) reduce to the greatest degree the volume and/or the dangerousness of the waste generated
    • d) list the best solutions for your treatment and disposal.

    The operations of pruning and removal of urban trees generate waste in the form of twigs, branches, leaves, seeds, fruits, stems and roots. According to the State Policy on Solid Waste, Law No. 12,300 ( SÃO PAULO, 2006), this waste is classified as urban waste.
    To decide which action should be applied, it should be taken into account that each individual tree has different needs related to the species, depending on its morphological and physiological characteristics. In addition, it is important that an assessment of the tree be carried out, observing the phytosanitary state, analyzing in more detail the trunk, the root, the branches, the leaves and the conditions of the place where it is planted.
