The increased request for poultry meat and eggs of a rising human population requires more efficient and cleaner methods to manage increasing quantities of chicken manure. The black soldier fly Hermetia illucens is known as an efficient bio-converter of organic waste in proteins and fats, with the advantage that the larval frass is supposed to have compost-like properties. In the view to identify the

Diaries have been used to obtain national and subnational estimates of household food waste (HHFW) in several countries. Furthermore, diaries have been proposed as a method for tracking progress towards goals that include HHFW reduction. However, multiple studies have suggested diaries substantially underestimate HHFW. This paper collates and analyses data from five studies in which diary estimates

The hydrological responses of geographically isolated wetlands to climate change is insufficiently considered and qualified, with weak but critical hydrologic connectivity to surrounding uplands. This study simulated the essential physical hydrological processes under climate change by coupling a distributed process-based model with an assemblage of 20 general circulation models under Representative

However, little research has explored the relationship between operational energy and life cycle cost performance of buildings. This paper aims to investigate

Titanium resources, with many outstanding properties, is abundant in the earth's crust, while large-scale application of titanium has been substantially restricted by two key challenges, i.e. high production cost and low utilization. Currently, metallurgists have paid great attention to develop a new extraction process for achieving the goal. However, the sustainable recycling of titanium currently

Electronic (e−) invoices potentially enhance environmental sustainability in several stages from production of paper to its usage. This study investigates empirically to what extent a set of firm characteristics and external factors associate with the probability to send e-invoices and with the intensity of usage, based on a representative survey of approximately 1500 Swedish firms. An invoice is considered

Food waste is a major barrier to a sustainable society. Cleaner production is most effectively approached by amongst others avoiding waste. A lot of food waste is due to consumer perception of sub-optimality of foods, and supermarkets can offer ‘imperfect’ products to consumers at a reduced price in order to fight food waste. However, little is known about how this is perceived by consumers and whether

Quantitative analysis of the spatiotemporal changes in China's industrial wastewater and the hidden driving factors can provide important information for the overall process management of industrial wastewater. Taking China's 31 provincial-level administrative regions as research objects, this paper employed spatial econometric (OLS) model and geographically weighted regression (GWR) model to evaluate

Incineration of sewage sludge (SS) in waste incinerators is one of the main ways of SS disposal. In order to reuse the incineration bottom slag, chemical speciation and environmental risk of heavy metals of bottom slag during co-combustion of municipal solid waste (MSW) and SS should be evaluated. When co-combusted with SS, the proportion of mild acid-souble fraction of Cr, Cu and Zn in the bottom

Rainwater harvesting (RWH) has become a popular water saving and conservation means across the globe. In many cities, a pre-determined rainwater tank size is generally selected without a detail water balance modelling at the location on interest. However, to achieve maximum benefit from a RWH system at a given location, it is desirable to design the system based on the site specific conditions (e.g

In order to develop the high efficiency and cost-effective particle removal technology, a novel particle removal unit combined flue gas condensation and acoustic agglomeration was designed based on theoretical analysis.

For this purpose, a bibliometric and a cluster analysis by fractional accounting have been carried out using two of the most important databases: Web of Science (WoS) and Scopus. The research found and studied 1,222 documents from the WoS Core Collection

Fraction transformation is the intrinsic driving force of risk formation and the evolution of sites polluted with heavy metals. This process is usually a long, slow and spontaneous process characterized by a gradual linear release of the most stable to the most mobile fractions, in accordance with fraction stability, leading to the thermodynamic static risk of the site. However, this process may be

New ventures are increasingly recognized as candidates for creating novel sustainable products that challenge existing practices. Yet, succeeding in product innovation for such ventures is challenging due to various uncertainties pertaining to product development, potential demand and sustainability impact of their products.
