A set of primary compression settlement apparatus was designed in order to evaluate the compression characteristic of bioreactor landfill and forecasting primary compression settlement of garbage body under load. The primary compression settlement test of landfill was conducted by this apparatus in laboratory. Three groups of parallel tests were carried out. When daily average settlement is less than 0.1 cm, the test is over. At the end of the test, the primary compression settlement reached 68%, 63% and 60% of a total settlement respectively. Test showed that domestic garbage is a highly compressibility material. There exists the direct relation between primary compression settlement and initial dry density. Simultaneously, the compression settlement rate decreases with load increasing.

“…The stability assessment remains generally based on limit-equilibrium, with Mohr-Coulomb strength parameters. Since the first Brazilian values of 13.5 kPa for cohesion and 22°for effective friction angle, obtained from back-analyzing the Bandeirantes landfill failure (Benvenuto & Cunha, 1991), national research has been developed (Machado et al, 2002;Mahler & Lamare Neto, 2003;Campi & Boscov, 2011;Norberto et al, 2020;Daciolo, 2020;among others), including more advanced constitutive models (Machado et al, 2002;Mahler & Lamare Neto, 2005;Malavoglia, 2016;among others). Since landfills undergo large settlements, modeling of compression time evolution remains important.…”

Environmental Geotechnics has been an established branch of Geotechnical Engineering for about 40 years. The contribution from Brazilian practitioners and researchers is meaningful in the many activities in this field. This paper proposes to discuss three topics of relevance to modern sustainability in Brazil, in which Geotechnicians could have an even greater involvement: expansions in MSW landfills, geotechnical confinement and other geotechnical solutions for remediation of contaminated land, and reuse of wastes as geomaterials. First, important aspects of the environmental protection system recommended for landfill expansions are described through examples, as well as the possibility of immersing geogrids to reinforce the MSW mass and increase storage capacity. Secondly, an industrial-site case study is presented to point out the additional challenges associated with site remediation at an urban region of past industrial land use and the importance of a joint regional investigation and remediation plan. The possibility of benefiting from geotechnical confinement and in situ passive remediation to treat the area also is highlighted. Finally, on the third topic, preparedness to accept working with wastes in geotechnical works is encouraged, and two investigation examples on the reuse of construction and demolition waste and water treatment sludge are presented and discussed.

Methane has 21 times more greenhouse gas potential than carbon dioxide. Because of that, it is of great importance to adequately manage biogas emissions from landfills. In addition, it is environmentally convenient to use this product as an alternative energy source, since it prevents methane emissions while preventing fossil fuel consumption, minimizing carbon dioxide emissions. Performed analysis indicated that biogas capturing and energy generation implies 3 times less equivalent carbon dioxide emissions; however, a change in the Argentinean electrical market fees are required to guarantee the financial feasibility of the project.
