Medical establishments play important roles in different activities by using of modern technology to serve the humans and the environment through different departments in the establishment and its firms. Medical wastes are considered as a hazardous waste because they contain toxic materials, infectious, or non-infectious wastes and they are considered as a hazard to millions of patients, health...

The edible mushroom Pleurotus ostreatus has been studied as a potential crop to reduce agricultural solid wastes and increase mushroom production. P. ostreatus cultivated on various agricultural wastes singly i.e. rice straw (RS), rice husk (RH) wheat straw (WH), barley straw (BS), and cotton wastes (CW). The biological efficiency (B.E) was 25.61, 9.51, 22.6, 21.628 and 25.78 % while rounding u...

Mercury is receiving more concern due to its high mobility and high toxicity to human health and the environment. Restrictive legislations and world-wide efforts have been made on mercury control, especially the release and disposal of mercury-contaminated wastes. This paper describes a novel technology for detoxifying mercury-containing solid wastes with thiosulfate salts. Various parameters w...

Dental offices produce a variety of dangerous wastes during normal business day. Most of these waste are non-hazardous that can be managed as household wastes; however, some component are hazardous and can pose a risk to human and the environment if discarded to Municipal Solid Wastes. These types of wastes must be managed separately. Therefore, the aim of this study was to assess the component...

Anaerobic digestion (AD) is a process by which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion can be used to treat various organic wastes and recover bio-energy in the form of biogas, which consists mainly of CH4 and CO2. A great option for improving yields of anaerobic digestion of solid wastes is the co-digestion of multiple substrates. Numerous...

in this study, micromorphological properties of some samples collected from pedons polluted with petroleum refinery wastes and some adjacent unpolluted pedons were studied. after description of the studied pedons, disturbed and undisturbed samples were collected for physicochemical and micromorphological analyses. the results showed that the physicochemical properties (i.e. structure, bulk dens...

Improper management of solid wastes from healthcare services is a source of contamination and risk to the environment and to the public health. Emphasizing this matter in the process of education requires to take into account the individuals that work in these spaces, for constructing an ethic conscience, aiming at quality of life and sustainability. In order to know the approach on the managem...

This paper reviews the application of carbonation technology to the environmental industry as a way of reducing carbon dioxide (CO(2)), a green house gas, including the presentation of related projects of our research group. An alternative technology to very slow natural carbonation is the co-called 'accelerated carbonation', which completes its fast reaction within few hours by using pure CO(2...

Currently, much of our biodegradable wastes such as kitchen wastes, agricultural wastes & animal wastes are used to produce Biogas, a powerful greenhouse gas. Anaerobic digestion (AD) is a treatment that composts these wastes in the absence of oxygen, producing a biogas that can be used to generate Heat & Power. Producing renewable energy from our biodegradable wastes helps to tackle the energy...

The all-trans-β-carotene is a natural pigment used in various industrial fields (food, cosmetics, pharmaceuticals, etc) and possesses the higher provitamin A activity, in respect to other carotenoids. All-trans-β-carotene is produced industrially by chemical and biotechnological means. For β-carotene biotechnological production in industrial scale mated cultures of Blakeslea trispora, a heterot...
