Green Human Resources: Strategies for a Sustainable Future

Serap Kaymakcı — Sun, 30 Jun 2024 00:00:00 +0300

The analysis of the consequences of the Industrial Revolution, which affected various aspects globally including the economy, society and the environment starting with the late 18th century in England, has been in the limelight for quite some time. The exploitation of fossil fuels caused Global warming and greenhouse gases degeneration. Other than that, large scale farming practices that involve the application of heavy pesticides have worsened the situation. The environmental degradation that originated in this time period became the subject of scientific investigation in the twentieth century. Green Human Resource Management (GHRM) is a progressively management principles that embodies all imp074_ t885bort un corporate social responsibility in offering Human Resources Services to the organization. GHRM transforms conventional HR functions, like, recruiting, training, evaluating performance etc, into green variants in a bid to recruit eco-friendly personnel and prepare them for achieving organizational environmental objectives. These actions assist corporations in meeting their obligations towards the external environment and in achieving their corporate social responsibility (CSR) objectives. The successful application of GHRM strategies allows organizations to reach their sustainability objectives, achieve the competitive advantage, and generate economic benefits. Employee eco-centrism and effectiveness of the management of GHRM strategies, as practice underpinned by use of information technology. Therefore, the aim of this study is to provide information about green human resources in the context of global climate change, sustainability and future trends.

Biomass Carbonization, Briquetting and Briquette Characterization: A Review

Mon, 30 Jun 2025 00:00:00 +0300

Briquetting is a contemporary means of converting waste biomass into a high calorific value solid fuel through densification of biomass-binder mixture. The process of briquetting is carried out in different ways depending on the type of biomass, binder or desired properties of the briquettes, the economic value and heating efficiency of the biomass as a fuel. This review paper aims at demonstrating the research achievements attained so far in the use of various forms and sources of biomass, the different binders and binder formulations, biomass carbonization, briquetting techniques and the characterization methods used to study the qualities of briquets. The future of biomass recycling to solve world energy crisis is a topical issue. Conversion of biomass into fuel briquettes can be a sustainable endeavour if research directs its focus on availability and renewable nature of raw materials given the seasonal nature of some types of biomass and binders.

Air Pollution Estimation and Trends in Mainz 2017-2022: A Case Study

Sahar Gerandanesh, Felien Tee, Håkan Lane — Mon, 30 Jun 2025 00:00:00 +0300

Air pollution is a pressing global environmental challenge, with PM2.5 (particulate matter with a diameter of less than 2.5 micrometers) being recognized as one of the most hazardous pollutants to human health. Prolonged exposure to PM2.5 has been linked to respiratory diseases, cardiovascular conditions, and premature mortality. It has been shown that 99% of the world population is exposed daily to pollutant concentrations exceeding the World Health Organization’s recommended safe levels. This study compares PM2.5 levels measured by satellite data from the Atmospheric Composition Analysis Group at Washington University in St. Louis with ground-based measurements from the Sensor Community initiative using SDS011 sensors deployed in Mainz, Germany. In addition, we investigated whether Mainz has achieved a positive trend in reducing PM2.5 concentrations and assessed how well the city complies with WHO standards. Our results indicate that: (a) satellite measurements consistently record higher PM2.5 values than ground-based sensors, (b) Mainz has experienced a decreasing trend in PM2.5 levels in recent years, although some of this reduction may be attributed to pandemic-related lockdowns, and (c) pollution levels in Mainz remain significantly above WHO guideline limits.

Bu çalışmada, keranji (Dialium indum L.) odununun, antik ve tarçınlı doğal ahşap yağları ile muamele edilerek, yüzey özelliklerindeki değişiklikler incelenmiştir. Farklı yağ türlerinin, odunun renk parametreleri, parlaklık ve beyazlık indeksi üzerindeki etkileri ölçülmüştür. Yapılan testler sonucunda, her iki yağ türünün de ahşap yüzeyinde belirgin değişikliklere yol açtığı gözlemlenmiştir. Uygulanan her iki yağ türüyle h^o, C*, b* ve L* değerlerinin azaldığı, a* değerlerinin ise arttığı görülmüştür. ∆E* değerleri, antik yağ uygulaması ile 16.62, tarçınlı yağ uygulaması ile ise 11.60 olarak elde edilmiştir. Beyazlık indeksi değerlerinde ise her iki yağ türü de düşüş göstermiştir. Elde edilen sonuçlar, ahşap yüzeylerine uygulanan doğal yağların, ahşabın estetik ve fiziksel özelliklerini nasıl etkileyebileceği hakkında önemli bilgiler sunmaktadır. Ayrıca, çevre dostu ve sürdürülebilir malzeme kullanımı açısından bu tür doğal yağların potansiyeli vurgulanmıştır. Bu çalışma, gelecekte yapılacak araştırmalara katkı sağlamasının yanı sıra, ahşap işleme endüstrisinde estetik ve fonksiyonel özellikleri geliştirmeye yönelik çevre dostu alternatif yüzey işlemlerine de ışık tutmaktadır.
