Biomass is defined as organic matter from living organisms represented in all kingdoms. It recognized to be an excellent source of proteins, polysaccharides and lipids and, such, embodies a tailored feedstock for new products processes apply green industries. The industrial focused on the valorization terrestrial biomass are well established, but marine sources still represent untapped resource. Oceans seas occupy over 70% Earth’s surface used intensively worldwide economies through fishery...
Abstract The current enthusiasm for the circular economy (CE) offers a unique opportunity to advance impact of research on sustainability transitions. Diverse interpretations CE by scholars, however, produce partly opposing assessments its potential benefits, which can hinder progress. Here, we synthesize policy‐relevant lessons and directions sustainable identify three narratives—optimist, reformist, skeptical—that underpin ambiguity in assessments. Based 54 key scholars’ insights, needs:...
For decades, significant work has been conducted regarding plastic waste by dealing with rejected materials in masses through their accumulation, sorting and recycling. Important political technical challenges are involved, especially respect to landfilled waste. Plastic is popular and, notwithstanding decrease policies, it will remain a material widely used most economic sectors. However, questions of recycling the contemporary world cannot be solved without knowing material, which can...
Implementation of construction works on weak (e.g., compressible, collapsible, expansive) soils such as peatlands often is limited by logistics equipment and shortage available applicable materials. If preloading or floating roads geogrid reinforcement piled embankments cannot be implemented, then soil stabilization needed. Sustainable in an environmentally friendly way recommended instead applying known conventional methods pure cementing excavation a single replacement soils. Substitution...
The present research studies the characterisation and physico-chemical properties of an excavated fine fraction (<10 mm) from a Swedish landfill, Högbytorp. results showed that represents 38% by mass total wastes it contains mainly soil-type materials minerals. Higher concentrations zinc, copper, barium chromium were found with higher than Environmental Protection Agency (EPA) for contaminated soil. moisture organic contents 23.5% 16.6%, respectively. analysed calorific value (1.7 MJ kg-1),...
Landfill mining is an alternative technology that merges the ideas of material recycling and sustainable waste management. This paper reports a case study to estimate value landfilled materials their respective market opportunities, based on full-scale landfill project in Estonia. During project, dump site (Kudjape, Estonia) was excavated with main objectives extracting soil-like final cover function methane degradation. In total, about 57,777 m 3 processed, particularly uppermost 10-year...
Growing global production leads to continuing generation of waste, part which still ends its life cycle in landfills and dumps. Despite the efforts waste reuse recycling self-degradation, existing old dumps remain a huge challenge for future. The majority can be identified as non-sanitary designated or former dumps, meaning hills fields abandoned garbage degraded inert masses without any with little aftercare maintenance. In contrast, term ‘landfill’ refers legally organized disposal sites...
The main components of landfill gas are methane and carbon dioxide. Emissions methane, a strong greenhouse gas, can be minimized by in situ oxidation the bioactive cover layer. Typically, organic-rich porous materials such as compost used for this process. In study, material biocover was obtained from same mining. objective to study spatial distribution gases efficiency degradation biocover. dioxide emissions were measured at 29 measuring points six times on surface once depth 0.5 m. highest...
Reusing organic waste as fertilizer is one method to reduce the use of mineral fertilizers and minimize disposal in landfills. Regulations have been enacted for processing recycling end products, but humic content has neglected. We studied seven composts with different input materials technologies. Humic substances (HSs) were detected all composts. The total carbon HSs constituted 8.7 ± 0.1% (SD)–27.0 0.2% compost dry matter. Spectral differences between samples FTIR spectroscopy could be...
Industrial and strategic significance of platinum group elements (PGEs)—Os, Ir, Ru, Rh, Pd, Pt—makes them irreplaceable; furthermore, some PGEs are used by investors as “safe heaven” assets traded in the commodity markets. This review analyzes from various aspects: their place geosphere, destiny anthroposphere, opportunity economy considering interactions among exploration, recycling urban ores, trade markets, speculative rhetoric, changes required for successful technological progress...
The urbanization and increasing growth of planet's population accumulates significant volume disposed waste as well increases risks on human health environmental safety.Landfill systems are the dynamic, living in space time, potentially harmful entities that must be managed careful smart way possible.There many studies related to landfill emissions such leachates methane.However, there is a need for advanced understanding hydrological regime climate change associated changes cycle.The...
Summary In this research, biogas production potential from beach wrack collected in Riga Gulf (Ragaciems, Jaunķemeri, Bigauņciems) and coastline of Sweden (Kalmar) was studied using an anaerobic digestion method. Selected masses laying ashore containing macroalgal biomass common macroalgae types specific to the Baltic Sea were mixed for consolidated samples. Anoxic fermentation untreated carried out 16 bioreactors applying a single filling mode at 38 °C. The study revealed that by utilizing...
This study presents the adsorption capability of a filter composed sand coated with cobalt nanomaterials (CoNM) for extraction manganese ions from aqueous media. The was performed in both batch and dynamic modes order to evaluate capabilities free-standing CoNM CoNM-coated sand. Langmuir Freundlich isotherm models were applied batch-mode. model estimated maximum capacity 17.86 mg/g corresponding single layer adsorption. Nevertheless, also characterized high coefficient determination,...
ABSTRACT In order to assess the effectiveness of aerobic degradation with emphasis on 16 U.S. EPA priority polycyclic aromatic hydrocarbons (PAH), oily sludge generated by a dissolved air flotation flocculation unit wastewater treatment plant in petroleum refinery was amended remediated oil‐contaminated soil and non‐mature garden waste compost 40:40:20 (wet weight) respectively. About 21 t mixture top‐layer formed 30 cm treated 28 m3 air‐forced reactor. The PAH concentration monitored for...
Landfill mining applied in reclamation at the territories of old dump sites and landfills is a known approach tended to global economic environmental benefits as recovery metals energy an important challenge. The aim this study was analyse concentration several metallic elements (Ca, Cu, Cr, Fe, K, Mn, Pb, Zn) fine fraction waste derived landfill compare results measurements obtained by field-portable equipment with data gained advanced analytical tools. Atomic absorption spectrometry (AAS)...
