Clean air and clean water. Two essentials for life on earth. In many ways, the use of filters is necessary for achieving this. Today’s market size shows total global revenues for filters in 2020 and projected for 2028. Growing concerns about reducing emissions from automotive and industrial applications as well as the increasing popularity of air and water purifiers among consumers will fuel demand for filters over this time period. 

By application, motor vehicles garnered more than 47% of the market in 2020, followed by consumer goods, utilities, industrial and manufacturing, and others. Increasing automotive production, especially in China, Indonesia, South Korea, Japan, Malaysia, and Taiwan along with stringent regulations aimed at reducing automotive pollution will create increased demand for automotive filters. Filters are used in several motor vehicle applications: oil intake, air filtration, and emission filtration. Filters for internal combustion engines accounted for more than 40% of the market in 2020. 

Fluid filter demand will increase due to the increased construction of water treatment plants globally. Fluid filters are also used in cold sterilization of beverages and pharmaceuticals, petroleum refining, dairy processing, and wine production. Air filters are expected to experience the fastest revenue growth through 2028 due to governments mandating the reduction of pollutants from vehicle emissions and the growing popularity of air purifiers that kill harmful bacteria and viruses in homes, hotels, airplanes, and train compartments. Demand for filters in the industrial and manufacturing sectors will center around Europe, North America, and the emerging industrialized regions of India, South Africa, Brazil, Thailand, and Indonesia.

The Asia-Pacific region held a 42% revenue share in 2020 due to the rapid industrialization in the region. The increasing pollution levels are leading governments to impose environmental quality regulations. As a result, demand for air and water filtration devices is expected to grow. In Europe, the rising demand for air filtration equipment in industries such as cement, chemicals, and metallurgy along with increasing adoption of air purifiers in Germany, France, Italy, and Spain will spur growth in this region. The North American automotive industry is expected to contribute to growth in filter revenue in this region. Also, technological breakthroughs in filtration processes, such as the implementation of nanotechnology, will lead to increased demand. In Central and South America, fluid filter demand is expected to significantly increase through 2028 as several wastewater treatment plants undergo construction due to growing water pollution levels in Brazil, Argentina, and Uruguay among others. The use of filters in Brazilian mining operations to control emissions is also expected to fuel demand in the region.

There are several major filter manufacturers around the world. Many companies are developing sustainable products that offer improved efficiency and value. Some are expanding their production capabilities to meet demand in various markets. Some major companies in this industry include 3M, Airex Filter Corp., Koch Filter, Freudenberg Filtration Technologies SE & Co. KG, Donaldson Co. Inc., Camfil AB, Parker Hannifin Corp., DENSO Corp., Clark Air Systems, and Spectrum Filtration Pvt. Ltd.

Scented Candles

scented candles
Organic candles made of soy wax and infused with essential oils have become popular in recent years.
Geographic reference: World
Year: 2018 and 2025
Market size: $310.7 million and $545.2 million, respectively

Balsam and pine. Gingerbread and peppermint. All scents that conjure in many warm feelings centered around the winter holidays. Whether or not you have live greenery in your home, bake cookies, or fill a candy dish with mints, your home can still be suffused with these aromas by lighting scented candles. Today’s market size shows worldwide scented candle revenues1 for 2018 and projected for 2025. In 2018, scented candles constituted 9% of the overall global candle market.

Candles have been used for thousands of years as both a source of light and in religious observances and celebrations. At this time of year, candles are used to light the menorah to celebrate Hanukkah, the kinara to celebrate Kwanzaa, the Advent wreath in anticipation of Christmas, and the farolitos that mark the homes hosting Las Posadas.

Some early civilizations made wax candles from available plants and insects. In the West, candles originally were made of animal fats. Burning them gave off an unpleasant odor. Scents were added to cover up the pungent smell. Other materials were used to make candles as well, such as spermaceti, beeswax, and paraffin. Beeswax candles emitted a sweet smell but were expensive. Gas and kerosene lamps, then lightbulbs, replaced candles as a way to light homes after dark. As a result, the popularity of candles waned until the mid-1980s when candles became a luxury decor item. Now, candles with colored waxes and decorative holders adorn homes. Scented candles are designed with aromatherapeutic elements to create a relaxing and cozy home environment. Essential oil infused organic candles made of natural ingredients such as beeswax, soy wax, and coconut wax have become more popular in recent years. Scented candles are also popular gifts, especially among millennials. For some, giving scented candles shows “the givers’ wishes for one to always remain enlightened even during the darkest of times.”2

Scented candles come in thousands of varieties, from simple scents such as rose, lavender, and vanilla to more complex blends of scents. Most premium products are comprised of three layers of fragrance, or notes. The top note provides the initial impression. The middle note is the main body of the scent. The base note provides the final impression. For example, Yankee Candle’s Balsam & Cedar has citrus, herbs, and red berries as its top note; pine balsam, cedar, and sandalwood as its middle note; and vanilla, warm amber, and musk as its base note. Together, these provide a woody, forest scent.

Container-based candles garnered 55% of the market in 2018. These candles are convenient for the user. They don’t require a separate holder or stand and the liquid wax remains in the container when the candle is burned. Container-based candles are popular gifts. 

In 2018, convenience stores accounted for about 60% of revenues. The large number of convenience stores in India, China, Japan, and Australia are driving sales in this segment. Sales at hypermarkets and supermarkets accounted for a quarter of revenues, with online sales rounding out the rest. Online sales are expected to grow the fastest from 2019 to 2025, at a compound annual growth rate of 9.2%, as more major retailers shore up their online presence. Some of the major online sellers of scented candles include Candle Warehouse, Amazon, Nordic West, Prosperity Candle, and Candles Scandinavia Group AB.

This growth prediction by Grand View Research, however, was made before the COVID-19 pandemic. E-commerce revenues had been growing even before the pandemic, but e-commerce sales overall have spiked in 2020. For the first half of the year, worldwide e-commerce revenues grew 16.5%, with many regions of the world registering higher sales growth. While most of the growth came from essential items such as food and household cleaning supplies, buyers are not limiting themselves to these items. The more people spend time in their homes the more they may want to add comforting elements such as scented candles to their online shopping carts. In the United States, online shopping records were set on Thanksgiving Day, Black Friday, and Cyber Monday, while in-store traffic on Black Friday was down more than 50%. Many people who used to buy holiday gifts, including scented candles, at brick-and-mortar establishments were opting to do all or most of their holiday shopping online this year.

North America claimed 35% of the market in 2018. Before the pandemic, this region was expected to continue to garner a large share of the market through 2025 due to the increasing number of spas, wellness centers, and massage therapy establishments. According to IBISWorld, the number of health and wellness spas in the United States grew from 17,829 in 2012 to 20,067 in 2019. However, the number dropped to 19,733 in 2020. Revenues dropped 7.7% from 2019 to 2020. For those that are still in business, temporary shutdowns and strict health department guidelines due to the COVID-19 pandemic are impacting the number of customers served. It’s likely that these types of businesses have been impacted similarly throughout the region, limiting demand for scented candles in this sector. The Asia-Pacific region is expected to experience the highest growth through 2025 as the popularity of gifting scented candles grows in countries such as China, India, Japan, Thailand, Australia, and New Zealand. Several major global manufacturers of scented candles include Newell Brands,3 KORONA Candles Sp. z o.o., Gala-Kerzen GmbH, The Very Good Candle Co., Goose Creek Candle, The Copenhagen Candle Company Ltd., Broken Top Candle Co., Bridgewater Candle Co., and Kringle Candle Co.

Enzymes are proteins that act as catalysts. Enzymes in the body run cellular processes and convert food to energy and to building blocks for proteins, lipids, nucleic acids, and some carbohydrates. Industrial enzymes such as proteases, amylases, lipases, and others are used in various applications: in the food and beverage industry, in detergents, animal feed, biofuels, textiles, pulp and paper, nutraceuticals, personal care products and cosmetics, wastewater treatment, and medications. In 2018, 60% of industrial enzymes on the market were proteases. In Europe, 900 tons of protease enzymes are used for detergents alone every year.

Today’s market size shows the global enzyme revenues for 2019 and projected for 2027. Microorganism-based enzymes comprised the vast majority of the industrial enzyme market in 2019, about 85%, followed by animal-based and plant-based enzymes. Microorganisms are preferred as a source due to their more predictable and controllable enzyme content. This type of enzyme can also be produced in a cost-effective manner with less space and time necessary than animal-based or plant-based enzymes. There are three types of microorganism-based enzymes: bacterial, fungal, and yeast. Bacterial enzymes are mostly sourced from Bacillus. They’re used in food and detergent and in pharmaceutical applications to diagnose diseases, promote wound healing, and kill disease-causing microorganisms. Fungal enzymes are used in the preparation and production of soy sauce, beer, baked goods, processed fruits, and dairy products. Yeast is used in beer, baked goods, and industrial ethanol production.

Increased investment in biotechnology research for the development of specialty enzymes for medicinal and diagnostic purposes is one of the main factors driving product demand globally. Increasing demand from the food and beverage, biofuel, animal feed, and home cleaning sectors along with the growing consumption of functional foods will contribute to the growth in the market through 2027. By region, growing biofuel production in North America and Europe, as well as increasing meat production in Europe and the Russian Federation, are expected to contribute to growth in these regions. Enzymes are used extensively in meat processing to improve the tenderness of the meat. Europe was third behind China and North America in meat production in 2018. The top three companies in this industry—Novozymes, DuPont Danisco, and DSM— claimed more than 75% of the market in 2019.1 Other major companies in this industry include BASF SE, Associated British Foods PLC, Chr. Hansen Holding A/S, and Advanced Enzyme Technologies.

Wireless Speakers Enabled by Personal Assistants

Amazon Echo and Google Home are two versions of wireless speakers that do more than play music. They are also voice-activated personal assistants. Some of their capabilities include adjusting a smart thermostat, turning lights on or off, arranging a ride through Uber, and delivering the news, sports, and weather. As prices have come down for these devices, in some cases retailing for less than $50, popularity has risen.

Today’s market size is the value of the market for voice-activated wireless speakers/personal assistants in 2015 and the projected value of the market in 2020 according to Gartner. The value of the market is expected to increase more than 5-fold in this 5-year period.

Garage Storage and Organization

Products purchased to help organize the garage constitute the fastest growing segment of the home storage and organization market. In recent years, the garage has become more than just a place to park cars. Only 35% of garages made to fit at least two cars have room for more than one. While many homeowners use their garage for storage, there’s a growing segment of the population that use their garage as an extension of their home — installing granite floors, wide-screen televisions, and state of the art sound systems.

Data show the projected size of the garage storage and organization market in the United States in 2015. That year, the total home storage and organization market is expected to reach $9 billion, which means that the garage segment will represent nearly a fifth of the total market. Managing all of our stuff has become a real job and for some, a business.
