The Strategic Role of Waste Inventories in Industrial Symbiosis: A Simulation‐Based Perspective on Performance and Resilience of Industrial Symbiosis Networks

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Ensuring the resilience of industrial symbiosis networks (ISNs) has emerged as a key concern in the literature. However, existing studies focus on network‐level strategies, neglecting the potential benefits derived from strengthening the links between symbiotic partners.

Effect of the Changes in Bulk Density and Granulometric Properties on the Strength Properties of the Moulding Sand Mixtures

open access: yesInternational Journal of Engineering and Management Sciences, 2020
Foundry technology uses a lot of several natural materials. Sands use for preparing mixtures whereby making moulds or cores. Sand is defined as a granular, refractory major portion of mixture (90 – 98% in dependence on used binder).

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

open access: yesSustainable Development, EarlyView.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing

Waste foundry sand regeneration

open access: yesProceedings of XVI International Mineral Processing and Recycling Conference - zbornik radova
The casting industry uses large quantities of quartz sand, which is a cheap and accessible raw material that must be prepared for use in foundries. After the casting process, foundries generate huge amounts of waste foundry sand (WFS) as industrial waste.

Corrosion and wear in moulding boxes [PDF]

open access: yes, 1997
We assess the potential causes of damage to mould box ends and find that both HOT corrosion, due to burning of emitted volatiles, and COLD corrosion, due to the presence of high humidity (and possibly high chloride ion concentration), are likely to ...

The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

open access: yesStructural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

Medicine for the Material World

open access: yesArchaeometry, EarlyView.
ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...
