In recent years, the demand for hydrogen peroxide in the paper and pulp industry has significantly grown, due to improved paper quality and increased yield of wood mass. In addition, hydrogen peroxide is used in eco-friendly bleach products, in order to remove chlorine compounds through bleaching processes.  In the paper and pulp industry, hydrogen peroxide is primarily used for: Bleaching of wood pulp. Bleaching of cellulose. Recycling of wastepaper (de-inking)  North America, Asia, and Europe together account for most of the world’s paper and pulp production. China had the world’s largest paper and pulp production with 99.3 million metric ton as of 2018, followed by the United States. Other leading pulp and paper producers in the world include Germany, Japan, Finland, and Canada. The global production of paper and pulp is increasing constantly (as shown in the figure), despite at a slow pace. Potential regions, like Asia-Pacific, are witnessing an increase in the volume of paper production, since the demand for packaging has increased recently. This can be attributed to the growing demand for eco-friendly products and increasing sales of newspapers and books, due to growing population in the region.

Pap and HPV tests are vital for diagnosis of cancers and precancer stages in cervix. Mostly these tests are performed together for the patient age group between 21-65 years. As per the international Agency for Research on Cancer, more than 85% of cervical cancer patients are from the developing countries, which demands better efficacy screening and treatment programs for women’s health. Since the cancer progression is slow and may take up to 20 years to develop into an advanced stage, there are many opportunities to stop the disease before it becomes fatal. At present, there are many cities in the emerging market that lack resources for a good laboratory with highly trained cytotechnicians and other specialized staff, which is among the major challenges for good results from Pap testing. With the advancement of HPV tests, the prevention possibility of expansion of cervical cancers increases even in the low resource settings because it is a more affordable and cost-effective strategy, leveraging self-sampling potentially. There are countries, such as Australia and New Zealand, which have effectively taken positive measures related to proper HPV and Pap testing to eradicate cervical cancer. However, the current scenario demands more countries to take better initiatives to roll out the advanced screening tests of HPV and Pap through financial support from the government.

The proliferation of handheld devices has led to developments in the field of gas sensors, detector, and analyzer, which has considerably widened the scope of application across multiple end-user segments. Due to their chemical composition and properties, metal oxide gas sensors are well-suited for a wide range of applications, including the detection of all reactive gases. Depending on the material used and the gases that need to be detected, typical operating temperatures range between 300°C and 900°C. Currently, some of the prominent companies are developing products across the detector, as well as the analyzer segment having application across clinical assaying, environmental emission control, explosive detection, agricultural storage, and shipping, along with workplace hazard monitoring.

In the recent years, the sales of internal combustion engines, which are the main source of environmental pollution, declined significantly, primarily due to the rising awareness regarding environmental pollution. The pollution caused by automotive had been increasing drastically, since the past few decades, and it is estimated that about 30% of air pollution is primarily due to automotive emission. Sudden increase in automotive pollution considerably impacted the environment, intensifying the threat of air pollution in most of the big cities around the world.
