“…For substrates C2 (vegetable waste) and C4 (hay) inoculated with the consortium, and C6 (wheat straw) with RAT/5, an initial drop in the pH was recorded in the first 30 days. A similar pH drop was observed by Poincelot (1974), and White et al (1995) suggested that an alkaline pH could enhance the composting process, controlling pathogenic fungi that prefer acidic growth conditions (Saidi et al 2008). The decomposition of organic wastes at pH values of 6.0 or below can slow down the decomposition process, while pH values above 8.0 can cause the release of unpleasant smells associated with ammonia.…”

It is important to use renewable resources to maximize crop yields and minimize the environmental hazards associated with chemical residues. Composting is an age old practice for the biological conversion of organic waste to a humus-like substance which can enhance physical, chemical and biological soil properties. To explore the effect of microorganisms in the composting process, three potent bacterial isolates were selected. Their morphological, cultural and biochemical characteristics were identified, and 16S rDNA studies identified isolates B1U/1 and D3L/1 as Bacillus subtilis and isolate RAT/5 as Pseudomonas sp. Common organic wastes were composted using the selected isolates individually and as a consortium. The C/N ratio of each substrate reduced gradually to 25–30:1 within 120 days and remained constant thereafter. The reduction in NH4+ and NO3− ion concentrations also indicated compost maturity after 120 days. The pH of the mature compost was typically 7.0 ± 0.2, and the PO4−3 ion concentration was high throughout the decomposition process. This study describes the optimization of the composting process using a consortium of isolates from composted soil.

“…For any country, awareness and education are the two pillars on which the 3R approach stands and are supported by other factors, like population restriction, attitude, knowledge, and practices. Reduction is always considered the best way to manage any waste [ 150 , 151 ]. The key factor is reducing the purchasing amount or restricting only to buying what we need.…”

Excessive exploitation, negligence, non-degradable nature, and physical and chemical properties of plastic waste have resulted in a massive pollution load into the environment. Consequently, plastic entres the food chain and can cause serious health issues in aquatic animals and humans. The present review summarizes currently reported techniques and approaches for the removal of plastic waste. Many techniques, such as adsorption, coagulation, photocatalysis, and microbial degradation, and approaches like reduction, reuse and recycling are potentially in trend and differ from each other in their efficiency and interaction mechanism. Moreover, substantial advantages and challenges associated with these techniques and approaches are highlighted to develop an understanding of the selection of possible ways for a sustainable future. Nevertheless, in addition to the reduction of plastic waste from the ecosystem, many alternative opportunities have also been explored to cash plastic waste. These fields include the synthesis of adsorbents for the removal of pollutants from aqueous and gaseous stream, their utility in clothing, waste to energy and fuel and in construction (road making). Substantial evidence can be observed in the reduction of plastic pollution from various ecosystems. In addition, it is important to develop an understanding of factors that need to be emphasized while considering alternative approaches and opportunities to cash plastic waste (like adsorbent, clothing, waste to energy and fuel). The thrust of this review is to provide readers with a comprehensive overview of the development status of techniques and approaches to overcome the global issue of plastic pollution and the outlook on the exploitation of this waste as resources.

“…Several models for environmental assessment of treatment and disposal of municipal solid waste have been presented in the last decade. The IWM‐model (White et al , 1995; McDougall et al , 2001) applies life cycle thinking on handling of municipal solid waste and includes first a spreadsheet and later a more advanced model for calculating life cycle inventories. In our research, we started with LCA.…”

PurposeThe purpose of this paper is to focus on optimization of recycling of concrete from lightweight aggregates containing expanded glass and hard polyurethane (PU) and on the issue of importance of environmental management in constructions, to produce the new combination using rest, construction waste of concrete from lightweight aggregates and hard PU new raw components of concrete from lightweight aggregates, as key reactive materials.Design/methodology/approachThe research for this paper is based on the collection and analysis of quantitative and qualitative data, non‐linear programming (NLP) model and experimental research.FindingsResults from the new recycled material have been compared with the normal existing concrete from lightweight aggregates. Characteristics of recycled lightweight concrete (LWC) such as density, compressive strength and thermal conductivity have been investigated and have been compared with normal existing concrete from lightweight aggregates. Results indicate that it is possible to recycle LWC aggregates and hard PU waste.Research limitations/implicationsResearch was limited to management of construction.Practical implicationsThe use of waste LWC with aggregates containing expanded glass and hard PU seems to be necessary for the production of cheaper and environment‐friendly LWC.Originality/valueThe method shows great possibilities for increasing use of construction waste materials from LWC containing expanded glass and hard PU in order to benefit from the better use of existing construction waste. Characteristics such as density, compressive strength and thermal conductivity from the new recycled material have been compared with normal existing concrete from lightweight aggregates. They change depending on the type and part of waste as well as the type and part of fresh binding components. Thus, a new recycled material is created with new values of density, compressive strength and thermal conductivity, which conform to the compressive strength class and rules on heat protection and efficient use of energy in buildings (SI OJ RS No. 42/2002). Laboratory density, compressive strength and thermal conductivity tests results showed that LWC can be produced by the use of waste LWC with aggregates containing expanded glass and hard PU. The author proposes a model of recycling isolating materials, made of hard PU and LWC with aggregates containing expanded glass, based on recycling and NLP.
