Web-Resol Tudo sobre Limpeza Urbana e Resíduos Sólidos!
A fração orgânica putrescível dos resíduos sólidos urbanos pode ser aproveitada através do processo de tratamento
anaeróbio de resíduos sólidos orgânicos realizados com substrato contendo em média cerca de 5% (percentagem em
peso) de sólidos totais. A matéria orgânica vai gerar como produtos o biogás contendo em sua composição um
considerável percentual de gás metano e material bioestabilizado que pode ser utilizado como agente condicionador
de solos. O presente trabalho objetiva avaliar os parâmetros operacionais pH, AGV e AT no processo de
bioestabilização anaeróbia de resíduos sólidos orgânicos. O reator anaeróbio tinha capacidade unitária de 2200
litros, sendo 1850 litros destinados ao substrato afluente e o restante ao biogás produzido. O reator foi alimentado
diariamente com resíduos sólidos orgânicos frescos e com tempo de detenção de 90 dias. Após atingir o estado de
equilíbrio dinâmico, o biogás apresentava cerca de 60% de gás metano e a relação AGV/AT decresceu
gradativamente ao longo do período de monitoração

California SB 54 Is Here: What Companies Using Plastic Packaging Need To Do Now | JD Supra
SB 54, the Plastic Pollution Prevention and Packaging Producer Responsibility Act, was signed into law on June 30, 2022. Its goal is to create a framework that shifts waste management costs from the local government onto producers. To that end, SB 54 requires producers to (1) reduce the use of Covered Materials; and (2) ensure that all Covered Materials are recyclable or compostable by 2032. The definition of a producer is not 100% straightforward. You are considered a producer if you are the person who manufactures a product that uses covered material and who owns or is the licensee of the brand or trademark under which the product is used in a commercial enterprise, sold, offered for sale, or distributed in the state. [1] However, if no such person is located in California, the producer of the covered material is the owner or, if the owner is not in the state, the exclusive licensee of a brand or trademark under which the product using the covered material is used in a commercial enterprise, sold, offered for sale, or distributed in the state. [2] But if there is no such person in California either, the producer is the person who sells, offers for sale, or distributes the product that uses the covered material in or into the state. [3] To the extent you are a producer, the final regulations implementing SB 54 which went into effect May 1, 2026 have set near-term milestones with which you must comply. First, by June 1, 2026, all producers (subject to very limited exceptions) must either (1) participate in an approved Producer Responsibility Organization ( PRO ), or (2) decide to comply individually and register with CalRecycle. Depending on which path a producer decides to follow, it will also be subject to subsequent deadlines. Producers who plan to participate in an approved PRO must have a producer responsibility plan in place by June 15, 2026. If you choose to comply individually and register with CalRecycle, they must approve you, and once...
