infrastructures

Community and charitable reuse organisations provide significant social infrastructure that facilitates the redistribution of discarded items to new owners, but are often overlooked in circular cities initiatives. Drawing on a survey of 34 reuse organisations from across Australia and recorded interviews and site visits to 10 of these between 2021 and 2023, we characterise the processes, practices and types of organisations across the sector.

En este trabajo examinamos de manera crítica el papel dominante del hormigón en la modernización de las ciudades asiáticas desde mediados del siglo XX. Ya hace tiempo que constructores, arquitectos, urbanistas y ciudadanos destacan las ventajas del hormigón. Sin embargo, sostenemos que, en el Antropoceno, ya no es posible pensar el hormigón como un material neutro en términos sociales y medioambientales. Las fisuras del hormigón son tanto físicas como metafóricas; no solo se manifiestan en el material, sino también como problemas socioecológicos.

Aotearoa New Zealand is at a critical juncture in reducing and managing organic waste. Research has highlighted the significant proportion of organic waste sent to landfills and associated adverse effects such as greenhouse gas emissions and loss of valuable organic matter. There is current debate about what practices and infrastructure to invest in to better manage and use organic waste. We highlight the diversity of existing organic waste practices and infrastructures, focusing on Auckland, Wellington and Christchurch.
