Summary The recycling of material resources lies at the heart industrial ecology (IE) metaphor. very notion ecosystem is motivated by idea that we should learn from natural ecosystems how to “close loop.” Recycling not just central IE, it part everyday life. Unfortunately, IE community and public large think about includes several misconceptions have potential misguide environmental assessments, policies, actions deal with thus undermine its potential. One misconception stems naïve...

Abstract Derelict abandoned, lost and discarded fishing gear have profound adverse effects. We assessed gear-specific relative risks from derelict to rank-order methods based on: production rates, quantity indicators of catch weight grounds area, consequences gear. The latter accounted for ghost fishing, transfer microplastics toxins into food webs, spread invasive alien species harmful microalgae, habitat degradation, obstruction navigation in-use gear, coastal socioeconomic impacts....

Global population growth and changing diets increase the importance, challenges, of reducing environmental impacts food production. Farmed seafood is a relatively efficient way to produce protein has already overtaken wild fisheries. The use protein-rich crops, such as soy, instead fishmeal in aquaculture feed diverts these important sources away from direct human consumption creates new challenges. Single cell proteins (SCPs), including bacteria yeast, have recently emerged replacements for...

Abstract Derelict fishing gear is a highly visible source of marine plastic pollution, causing mortality and ecosystem degradation with uncertain long‐term consequences. The quantity derelict entering the oceans remains unknown because heterogeneity in effort, as well inadequate monitoring. Prior studies have been limited scope to specific fisheries regions, large‐scale estimates lack an empirical basis. It critically important for decision makers credible information order design effective...

Summary With the growth of field industrial ecology (IE), research and results have increased significantly leading to a desire for better utilization accumulated data in more sophisticated analyses. This implies need greater transparency, accessibility, reusability IE data, paralleling considerable momentum throughout sciences. The Data Transparency Task Force (DTTF) was convened by governing council International Society Industrial Ecology late 2016 propose best‐practice guidelines...

Observations of material and cellular systems in response to time-varying chemical stimuli can aid the analysis dynamic processes. We describe a microfluidic "chemical signal generator," technique apply continuously varying concentration waveforms arbitrary locations channel through feedback control interface between parallel laminar (co-flowing) streams. As flow rates streams are adjusted, walls exposed environment that shifts individual This approach be used probe behavior objects or...

We describe a system for dynamically adjusting the position of laminar interface between two fluids flowing inside microfluidic channel, with time response less than 0.1 s, through feedback control channel inlet pressure.

Life cycle assessment (LCA) is a highly interdisciplinary field that requires knowledge from different domains to be gathered and interpreted together. Although there are relatively few major data sources for LCA, the themselves presented with heterogeneous formats, interfaces, distribution mechanisms. The lack of agreement among providers descriptions processes flows creates substantial barriers information sharing reuse practitioners' models. Nevertheless, many resources share common...

Existing microfluidic systems can control local chemical environments by directing the interface between laminar flowing streams for applications ranging from subcellular stimulation to fuel cells. However, conventional flow modulation methods have not yet provided a robust and reliable way dynamically interfaces very long time periods. Such is important in biological investigations, since response times living cells tissues be as several days. Here, we describe novel long-term, high-speed...

The policies concerning product development and use are increasingly informed by life cycle assessment (LCA) risk (RA): LCA is often invoked to achieve "sustainability" whereas RA used when seeking avoid harm dealing with toxic substances. In this Feature, Kuczenski et al. argue that green chemistry principles—which encourage reducing the of chemicals processes—suggest a way combine in assessment.

Summary Many of the challenges facing knowledge synthesis from life cycle assessment (LCA) studies stem inability study authors and readers to formally agree on structure content product system models used perform LCA computations. This article presents a framework for disclosing foreground an in way that permits computations be inspected, verified, reproduced by reader, provided reader has access same inventory impact characterization resources as author. The can also partition into public...

Industrial fishing, instrumental in feeding the world's population while providing a livelihood to many people, also presents variety of hazards health ocean, including accumulation derelict fishing gear. Although direct evidence harm from gear is abundant, efforts quantify and assess threats posed by it are confounded part tremendous diversity techniques. In this paper, we advance novel analytic framework for describing use that can be applied evaluate environmental impacts arise activity....

Summary Extended producer responsibility (EPR) legislation in the United States, which currently only exists on state level, now includes three mattress EPR acts, intend to shift financial and operational burden of end‐of‐life (EOL) management away from local government. It is important keep mind, however, that original objective behind reduce environmental life cycle impacts products. This article therefore quantifies greenhouse gas (GHG) savings potential boxspring recycling reuse States...

Life Cycle Assessment(LCA) is crucial for evaluating the ecological sustainability of a product or service, and accurate evaluation requires detailed transparent information about industrial activities. However, such usually considered confidential withheld from public. In this paper, we present rigorous study privacy in context LCA. The main goal to explore challenges assessment considering protection trade secrets while increasing transparency To overcome concerns, apply differential LCA...
