A GREEN CHEMISTRY APPROACH TO THE FACILE SYNTHESIS OF AMINOANTHRAQUINONE DERIVATIVES

(STEF92 Technology, 2026, Andrejs Grigorjevs, Elena Kirilova, Romans Fridmans, Irena Mihailova, Sergejs Osipovs)

Show more

Developing processes with minimal environmental impact is essential for the production of the important intermediates and final products. Present study explores the green and low-cost synthesis of new halogenated derivatives of 1-aminoanthraquinone under catalyst free conditions at room temperature. These derivatives find wide practical application due to their unique properties. Numerous studies on the preparation of new derivatives have been devoted to the development of industrial dyes and pigments. These compo...

BIOCHEMICAL MODIFICATION AND HARVESTING OPTIMIZATION: A STUDY OF FOUR SEA BUCKTHORN VARIETIES

(STEF92 Technology, 2026, Ancuta Chetrariu, Ionut Avramia, Adriana Dabija, Irina Dianu, Artur macari)

Show more

Sea buckthorn is a heliophilous species valued for its nutrient-rich orange berries, which find extensive applications in the pharmaceutical, food, and agricultural industries. This study monitored four specific cultivars: Dora, Cora, Mara, and Clara, grown in the Republic of Moldova over a 60-day period (August to September). The research focused on tracking the evolution of primary ripening indicators: vitamin C, total carotenoids, and organic acid content. Ascorbic acid, a vital bioactive component, showed a co...

CHARACTERIZATION IN TERM OF THE SELF-IGNITION BEHAVIOR FOR COMBUSTIBLE DUSTS DERIVED FROM TECHNOLOGICAL PROCESSES

(STEF92 Technology, 2026, Irina Nalboc, Maria Prodan, Andrei Szollosi Mota, Sonia Suvar)

Show more

Combustible dusts are presented in industry as a finished products or process intermediates created voluntarily by milling or involuntarily by abraison of larger sized solid. Spontaneous combustion is a phenomenon that occurs by self-heating, increase in temperature due to exothermic internal reactions, followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. The oxidation of combustible powders occurs when they react with air oxygen, producing carbon dio...

E-WASTE MANAGEMENT IN KOCHI, INDIA: BEHAVIORAL DRIVERS AND CIRCULAR ECONOMY IMPLICATIONS

(STEF92 Technology, 2026, Naibin George, Andrejs Cekuls, Sweety Joy C)

Show more

This article identified the issue of electronic waste (e-waste) management in Kochi, India, amongst the country's rapid technological growth and escalating electronic consumption. It highlights the severe environmental and health risks of improper e-waste disposal, particularly in the informal recycling sector, which dominates India's recycling landscape. The article emphasises the need for a transformative shift from the existing cradle-to-grave (C2G) system to a Cradle-to-Cradle (C2C) model for circular e-waste ...

ENVIRONMENTAL IMPACT OF PLANT-BASED MILK ALTERNATIVES: AMARANTH, ALMOND, SOY

(STEF92 Technology, 2026, Mihaela Lacatus, Nicoleta Hadaruga, Monica Dragomirescu, Liana Maria Alda, Despina Maria Bordean)

Show more

In recent years, with the interest in healthy diet and environmental protection, plant-based alternatives, to classic milk, have been developed and produced. In addition to the already well-known products, such as almond or soy milk, amaranth milk is also becoming increasingly known. Amaranth milk is considered a possible alternative with both nutritional and ecological benefits. As a result of environmental problems and people's needs, this paper aims to compare these types of plant-based beverages, in terms of c...

IMPLEMENTATION OF INDUSTRIAL VENTILATION SYSTEMS AND ANALYSIS OF THEIR EFFICIENCY -CASE STUDY-

(STEF92 Technology, 2026, Razvan Dragoescu, Adrian Matei, Alexandru Camarasescu, EMERIC CHIUZAN)

Show more

The role of ventilation systems is to ensure and maintain optimal microclimate conditions in industrial spaces, by controlling temperature, humidity, dust concentration and gaseous substances, within limits compatible with comfort and safety requirements. At the same time, these systems must respect permissible noise levels and air circulation speed, so as not to affect the well-being of users. In order to achieve the prescribed parameters of indoor air (temperature, pressure and humidity), it is previously subjec...

THE ROLE OF CIRCULAR ECONOMY PRINCIPLES IN ENHANCING E-WASTE SUPPLY CHAINS IN EMERGING ECONOMIES

(STEF92 Technology, 2026, Naibin George, Andrejs Cekuls, Sweety Joy C)

Show more

Purpose Electronic waste (e-waste) is one of the fastest-growing waste streams globally, posing urgent environmental and social challenges, particularly in emerging economies where recycling infrastructure is underdeveloped and informal recycling practices dominate. This article examines how circular economy (CE) principles can be applied to enhance e- waste supply chains and promote sustainable management. Design/methodology/approach A systematic literature review (SLR) of 50 peer-reviewed articles published betw...
