Background: The feasibility of converting organic wastes into vermicompost and the effect adding such substrate on growth reproduction earthworm (Eisenia fetida) were investigated in present study through a two-factor factorial experiment with completely randomized design triplicate. Methods: first factor nine different treatment combinations included control; potato (P); carrot pulp (C); veget...
Manure residues have been identified as a major source of environmental pollution. Traditionally, the waste has been disposed directly or after composting, as soil amendments in the agricultural industry. Since this practice has resulted in the degradation of air, soil, and water resources, new regulations for protecting the environment have been promulgated to control land application of anima...
This study aims to produce a mix of enzymes through Solid State Fermentation (SSF) raw materials. Four different, easily available, agro-industrial wastes were evaluated as SSF substrates for production by Cryphonectria parasitica (Murr.) Barr. environmental strains named CpA, CpB2, CpC4, and CpC7. Among the tested wastes, organic wheat bran human use animal feed better supports C. growth prote...
Approximately one-third of all food produced for human consumption worldwide is wasted. The current waste management practices are not only costly but also have adverse impact on environment. In this study, black soldier fly (BSF) (Hermetia illucens) larvae were grown on food wastes to produce fat and protein-rich BSF prepupae as a novel strategy for efficient organic waste management. The lipi...
Background & objectives: Medical wastes are of great significance due to their potential environmental impacts. This study aimed to examine the medical waste management in hospitals of Ardabil city in 2016. Methods: In this cross-sectional study, hospitals of Ardabil city (7 hospitals) were studied. Initial data were obtained from library information, observation and checklist. Also, the quanti...
This research was conducted in order to investigate the possibility of using palm wastes compost as substrate for cultivation of Dieffebnbachia amoena at five levels (ratio of 0, 25, 50, 75 and 100% v/v as substitute for peat) and peat: perlite (4:1) treatment as control, as a randomized complete blocks design with three replications. Chemical and biological properties of palm wastes compost, p...
A total of 278 different isolates of filamentous fungi were screened using synthetic medium for respective ability to produce kojic acid. Nineteen, six, and five isolates proved to be low, moderate, and high kojic acid producers, respectively. Levels of kojic acid produced were generally increased when shaking cultivation was used rather than those obtained using static cultivation. A trial for...
Several committees were established by the National Association of Physicians for the Environment to investigate and report on various topics at the National Leadership Conference on Biomedical Research and the Environment held at the 1--2 November 1999 at the National Institutes of Health in Bethesda, Maryland. This is the report of the Committee on Minimization and Management of Wastes from B...
Spirulina (Spirulina platensis (Gomont) Geitler 1925) is a cyanobacteria used as an ecologically sound, nutrient-rich dietary supplement. These microalgae have the capability to produce least-cost protein per unit area compared livestock and are therefore being investigated address malnutrition food security. Apart from variety of components, such animal feed, fertilizer, cosmetics, produced Sp...
Construction wastes have become the major source of solid wastes in Hong Kong. Thousands of tonnes of solid wastes are produced every year from construction and demolition activities. Increasing generation of these wastes has caused significant impacts on the environment and aroused growing public concerns. Therefore, the minimization of construction wastes has become a pressing issue. This pap...
