This study presents the results obtained in compostability tests of organic fraction of municipal solid waste (OFMSW) digestate. The final aim was to obtain mature compost without phytotoxic effects. For the evaluation of the composting process, a novel parameter describing the performance of the composting process, the relative heat generation standardized with the initial volatile solid content (RHGVS0), was defined and evaluated at laboratory-scale. From these laboratory-scale test, the optimum operational conditions were obtained, a mixing ratio (v/v) of 1:1:0 (bulking agent:digestate:co-substrate) and with 15% of mature compost as inoculum. Subsequently, these optimum operational conditions were applied in the active phase of the composting pilot-scale reactor. The active composting stage took 7 days, subsequently a curing phase of 60 days was carried out at ambient conditions. After 30 days of curing, the mature compost showed a specific oxygen uptake rate (SOUR) of 0.14 mg O2/g VS·h, a germination index (GI) of 99.63% and a low volatile fatty acids (VFA) concentration (41.3 AcH mg/kgdm), being indicative of the good compost stability and maturity of the compost. The very good quality of the final compost obtained indicated that the RHGVS0 accurately describes the performance of the composting process.
<p>O presente artigo visa lançar as bases para uma análise da formação da <em>Unión de Cinematecas de América Latina</em> (UCAL). Criada em 1965, a UCAL visa dar visibilidade e articulação às jovens cinematecas latino-americanas. Por sua vez, a segunda metade dos anos 1960 pode ser interpretada como a consolidação ideológica do <em>Nuevo Cine Latinoamericano</em> (<em>NCL</em>), o que também põe em questão o papel de uma cinemateca em nosso subcontinente.</p>
