Waste Economy
The South African waste sector is transitioning from a landfill-centric model to one focused on waste diversion, driven by regulatory reforms and limited landfill airspace. While only 10% of waste is currently recycled, significant opportunities exist in the recovery of paper, plastics, glass, e-waste, and construction and demolition waste. In the Western Cape, the City of Cape Town generates 70% of the province's waste, presenting a concentrated market for alternative treatment. Waste-to-energy (WtE) projects face economic and regulatory hurdles, such as low landfill gate fees and electricity prices, but opportunities remain in small-scale biogas and large-scale REIPPPP projects. The report also highlights the role of Producer Responsibility Organisations (PROs) and the availability of green manufacturing incentives in Special Economic Zones like Atlantis.

Sustainable cities: lessons from a Swedish community-level initiative
The 'Sustainable Hökarängen' project utilized an action-research approach to promote resource-efficient lifestyles in a residential district of Stockholm. Key findings emphasize that engagement is most effective when activities are social and enjoyable—such as communal gardening and climate-smart cooking—rather than focused on areas where residents have limited control, such as apartment energy use. The project successfully established a network of 'Sustainability Ambassadors' and local movements like HOPP! to ensure continuity. While a parallel investment programme by Stockholmshem reduced heating energy use by over 30% per square metre, the community-level project found that social cohesion and peer interaction were primary drivers of behavioral change. The brief concludes that evaluating such initiatives requires a mix of quantitative and qualitative methods and long-term follow-up to determine if behavioral changes are sustained.

Comments on “Arecibo Waste-to-Energy and Resource Recovery Project Draft Environmental Impact Statement”
The document argues that the Arecibo Waste-to-Energy and Resource Recovery Project is unnecessary, economically unviable, and environmentally hazardous. It claims the Draft Environmental Impact Statement (DEIS) fails to meet National Environmental Policy Act (NEPA) standards by ignoring reasonable alternatives, underestimating public health risks—particularly lead exposure in a non-attainment area—and omitting cumulative impacts on human health and biological resources. The authors contend that the project violates the Rural Electrification Act's mandate to serve rural areas and would cause irreversible damage to the Caño Tiburones Natural Reserve.

The global context of mineral resources in northern Europe: geopolitical and sustainability dynamics
The document examines the role of northern Europe, particularly Sweden, in the global production of iron ore and copper. It analyzes how global demand, dominated by China, creates 'boom and bust' cycles that impact local economies and environments. Using Chile as a comparative case, it highlights how resource scarcity and social resistance can limit production, while China's market dominance creates geopolitical dependencies for exporting nations. For northern Europe, the brief suggests that stable regulatory frameworks and assured ancillary resources may attract investment, though stakeholders must remain wary of the social and political implications of foreign mining companies.

Good News From the Dump
The report finds that global methane emissions from landfills are likely 10-15 Tg CH4/yr, significantly lower than the ~35 Tg reported by IPCC-based methodologies. It argues that developing countries will not follow the historical trajectory of industrialized nations toward heavy landfill reliance due to established recycling cultures, space constraints in megacities, and high organic waste content. The author identifies a 'gulf' between waste management field studies and climate modeling, noting that IPCC defaults often overestimate landfilling rates and underestimate food waste fractions. Among mitigation options, aerobic composting is highlighted as the most viable for developing countries because it is low-cost, suited to high-organic waste, and reduces leachate. Projections suggest that expanding composting could reduce 2030 methane emissions by approximately 34% compared to a reference scenario, while combined incineration and composting could reduce them by 43%.

Autocomposites Workshop
The document identifies high raw material costs, long manufacturing cycle times, and a lack of automotive-specific design standards as primary obstacles to using carbon fiber composites in vehicles. It argues that reducing material costs from approximately $11/lb to $6-$8/lb is essential for viability. The proposed solution is a 'substitution to transformation' approach, starting with individual part substitutions (e.g., engine mounts or battery carriers) to build supply chain scale before moving to full body-in-white implementation. The briefing also emphasizes the need for advanced CAE tools for crash modeling and the development of recycling and repair processes to ensure lifecycle robustness.

Landfills and Incinerators in the CDM: Not Sustainable, Not Additional
The document contends that the Clean Development Mechanism (CDM) fails to ensure environmental integrity in the waste sector, creating perverse incentives that prioritize waste disposal over recycling and composting. It highlights the displacement of informal waste pickers, the issuance of carbon credits for 'business-as-usual' projects that lack additionality, and the failure of landfill gas capture systems to prevent significant methane leakage. Specific examples include the Timarpur-Okhla plant in Delhi, the Bisasar landfill in Durban, and incinerators in China.

King County Greenhouse Gas Emissions An Updated Geographic-plus Inventory, a Consumption-based Inventory, and an Ongoing Tracking Framework
The report finds that King County's 2008 Geographic-plus emissions were 23.4 million MTCO2e, with transportation as the primary source. However, a Consumption-based inventory reveals a much larger footprint of 55 million MTCO2e, driven by the production of imported goods and services. To better manage these emissions, the report recommends a tracking framework focused on a 'core' scope of buildings, transportation, and waste.

Metals in a Low-Carbon Economy: Resource Scarcity, Climate Change and Business in a Finite World
The report identifies significant risks of cumulative supply deficits for indium, tellurium, and neodymium by 2035, which could hinder the deployment of low-carbon technologies like photovoltaics and electric vehicles. Using a scenario calculator based on IEA and WEF frameworks, the study finds that indium and tellurium face severe risks, while cobalt and lithium show limited risk. The photovoltaic industry is highlighted as particularly vulnerable, specifically second-generation thin-film technologies. Proposed mitigation strategies include material substitution, vertical integration, and increased recycling, though the latter faces technical and economic hurdles. The report argues that current government policies often treat scarcity as a technological issue, neglecting the geopolitical and economic risks that can exacerbate supply bottlenecks.
