There is no doubt that the world’s population is growing and has actually exceeded 7 billion. Feeding these 7 billion people is a huge challenge to the infrastructure of every country on our planet, from finding enough land for farming and raising livestock, providing nutrition for the land so that it can grow healthy food, to Transport the world's harvested plants to processing plants and markets.

Organic Fertilizer

Another aspect of the food chain is the organic waste generated throughout the process. Organic waste is any type of material, an unused by-product of another process, and has a decomposable cellulose structure. Including everything from the stalks left after the wheat is harvested to the manure produced by the animals after meals, organic waste is also multiplying at an increasing rate. Because more space is needed to accommodate 7 billion people, there is not much space for storing organic waste on Earth. When we try to find innovative solutions to deal with our naturally occurring organic waste, overflowing landfills and immersing nutrients and waste into the organic saturated soil of the local water supply are just two of the problems.

This article takes a look at the three central types of organic waste- agricultural, industrial, and municipal- and examines the challenges and opportunities associated with organic waste generation.

Municipal Waste

The third type of organic waste generated today is municipal waste. This is the trash that is collected by every city and town across each nation. According to the EPA, the U.S. generated 4.4 pounds of municipal waste per person per day in 2013, but only recycled or composted 34.3 percent of that material. Organic components make up over half of municipal waste, and include a variety of biosolids ranging from lawn clippings and trimmed branches, to spoiled food and a wide assortment of paper and cardboard products. While many European communities mandate the separation of all organic materials at the source (i.e., the home or business), this is not the case in the U.S., or in most countries around the world. Instead, the organic waste is mixed with inorganic garbage, sealed inside plastic bags, and dumped into overflowing landfills.

Agricultural Waste

Agricultural waste includes livestock manure and a variety of compostable items, such as those grain stalks mentioned above. Once upon a time, farmers would set aside part of their land as a composting ground for the manure and compostable materials generated in the process of growing plants and raising animals. With 7 billion people on the planet, land is now at a premium and there are few farms left with space available to allow manure to decompose and compost to mature at a slow, natural rate. This has resulted in many farmers having their manure hauled elsewhere, a practice limited by the costly expense of transporting a moisture-laden material more than a few miles from the farm.

Industrial Waste

The second type of organic waste is industrial. This includes the organic byproducts of processes in a variety of industries. Restaurants generate a large amount of organic waste, and according to, as much as 33 million tons of food are thrown out each year in the U.S. alone. Food spoilage in transit also generates organic waste at the distribution, market and grocery stages.

Another source of industrial organic waste is through Dissolved Air Flotation, or DAF, technology, which is increasingly being used in a variety of industries to remove suspended solids, fats, oils and greases from water-based solutions. This method of capturing particles is more efficient than older methods, which required waiting until solids would naturally settle via gravity at the bottom of sludge ponds (also requiring a lot more space). DAF also allows for the early removal of non-biological pollutants, such as petrochemicals, which results in a sludge that is purely organic in nature. Examples where DAF technology is being used include fish farming, meat processing, and paper and pulp manufacturing. DAF is increasing the amount of potable water available, but it is also generating large amounts of thick organic sludge which must somehow be disposed of—or, ideally, recycled.

Processing Organic Waste Into Fertilizer

There are many nutrients hidden in all three types of organic waste, and these nutrients are urgently needed to fertilize the next generation of crops. Fortunately, there are some creative minds at work on innovative answers to harnessing organic waste. One such solution is processing those wastes through organics granulation, which involves the drying and granulation of that organic waste into fertilizer pellets. In addition to removing organic wastes from overburdened farms and landfills, organics granulation creates a much-needed product that revitalizes farmland and helps the earth maintain its ability to feed more than 7 billion people.

Richi’s Experience in Transforming Organic Wastes Into Valuable Products

RICHI has worked with organic wastes since our founding in 1951. From then on, we’ve built a repertoire in turning agricultural, industrial, and municipal wastes into organic-based fertilizer products. From lab testing in the RICHI Innovation Center, to engineering, process development, design and equipment manufacturing, our team is highly skilled in the field of organics granulation.

The summary below highlights projects from our experience with each type of organic waste:

Agricultural Waste. The plant agglomerated raw and digested hog manure, using biogas to offset the heat requirements of the process. The overall set-up created a fertilizer-grade organic product that could be applied to fields with traditional fertilizer equipment.

Industrial Waste. Waste paper sludge is typically a landfilled byproduct as a result of industrial processing. ELLC recognized this waste problem and the opportunity in turning it into a useful, marketable product. That’s where RICHI stepped in. RICHI designed and manufactured a complete system to process the waste paper sludge and transform it into a variety of lawn and garden products.

Municipal Waste. RICHI has also designed bio-fertilizer granulation plants for food waste and biosolids to name a few. Each have been custom designed and built to suit the unique needs of the material being processed.

RICHI’s organics granulation system is a sound solution to the problem of agricultural, industrial, and municipal waste generation and disposal. While most companies specialize in a single part of the process, RICHI offers customers a unique advantage in that we can provide them with a complete solution, including everything from feasibility testing in the RICHI Innovation Center, through the design and manufacturing of custom equipment.
