Background

Sugarcane (Saccharum officinarum) is a tropical grass native to Asia where it has been grown for over 4,000 years. By 400 BC, methods for manufacturing sugar from sugarcane had been developed in India. Europeans were introduced to sugar during the Crusades. By the 11th century AD, sugar was being imported throughout Europe. Christopher Columbus likely brought the plant to the West Indies. Today, over 75 percent of the world's sugar comes from sugarcane.

Sugarcane was one of the first "cash crops" of early colonial America. It grew plentifully in the southern states and was a major source of income for many plantations. High labor costs in the United States led to the industry's rapid conversion to mechanical harvesting in the early 1990s.

Production

Sugarcane is grown primarily in the tropics and subtropics. In the United States, sugarcane is grown commercially in Florida, Louisiana, Texas and Hawaii. Cane for sugar was 26.7 million tons in 2011. In 2010, cane for sugar was valued at nearly $1.1 billion. The 2011 crop value data was not available for this report.  (NASS)

Florida, the top producing state, produced more than 13.1 million tons of sugarcane for sugar in 2011. The state typically contributes about half of the total U.S. cane sugar crop. That same year, Louisiana produced more than 10.8 million tons of sugarcane. Texas and Hawaii also produce more than one million tons annually.  (NASS)

According to the 2007 Census of Agriculture (2009), the number of sugarcane farms dropped from 953 to 692, while average area harvested grew from 1,027 to 1,224 acres per farm.

World sugar production for 2010/2012 is estimated at 168,247 metric tons raw value (MTRV), up from last year's production. Brazil is, by far, the world's largest producer of sugarcane, accounting for one third of world production. Asian production, which includes India, China and Thailand, accounts for another one-third of the world production. India is the world's second largest producer of sugarcane and China is the fourth largest.  (FAS)

Consumption and Industrial Use

After peaking in 1972 at 102 pounds per person, the use of sugar (both cane and beet) in domestic food and beverage industries had declined to a low of 60 pounds per person by 1986. In following years, per person sugar use by these industries fluctuated between 61 and 66 pounds. By 2010, according to USDA sources, Americans consumed 66 pounds of refined sugar per person. In contrast, Americans consumed 64.5 pounds of corn-derived sweeteners and 1.5 pounds of honey and edible syrups that year for an annual total sweetener consumption per person of 132 pounds (excludes artificial sweeteners).  (ERS)

Sugar deliveries to food manufacturers generally constitute a major portion of refined sugar deliveries. Of those industries, baking and cereal industries are generally the largest end users of sugar followed by confectionery makers. 

According to the USDA, sugarcane’s share of combined sweetener production rose from more than 70 percent in 2000 to nearly 79 percent in 2009. Cane costs were also higher in 2009 than in 2000. Increasing fuel and chemical costs were primarily responsible for increases in overall sugarcane costs.  (ERS)

Processing

The process of separating sugar from the sugarcane plant is accomplished through two steps: sugar mill crushing and sugar refinery extraction. Sugarcane is initially processed into raw sugar at mills near the cane fields. Because cane is bulky and relatively expensive to transport, it must be processed as soon as possible to minimize sugar deterioration. The raw sugar is then shipped to refineries to produce refined sugar. The final products of refining include powdered, granulated and brown sugar, which is sugar that contains some molasses.

The number of sugarcane mills has steadily declined. In 2005, 21 cane sugar millers remained in business, with a combined milling capacity of 293,930 tons daily. With 13 mills, Louisiana had a daily milling capacity of 164,630 tons. Florida had five operating mills, Hawaii had two mills and Texas had one.

As of 2005, eight sugarcane refineries operated in the United States, dominated by the Domino Sugar Corporation and the Imperial Sugar Company. Dominos' three plants are located in Louisiana, Maryland and New York. Imperial operates plants in Georgia and in Louisiana. Florida's sugarcane is refined by two companies: U.S. Sugar and Florida Crystals Corporation. The other refinery, located in California, is C&H, which has the largest capacity of any U.S. sugarcane refinery. It can process 3,400 tons of raw sugar each day. Four refineries have closed in the last decade. Thirty years ago, there were over twenty in operation.

The first sugar refinery built in a century was constructed in Louisiana adjacent to an existing refinery. Imperial Sugar Company, Cargill and Sugar Growers and Refineries LLC, a cooperative representing 700 sugarcane growers and eight mills, joined forces to fund the million-ton-per-year sugar refinery, which began commercial production in 2011.

Currently, no U.S. plants are producing ethanol from sugarcane or sugarbeets on a commercial scale.

Value-added Products

Sucrose
The type of sugar produced by sugarcane is called sucrose. It is used as a sweetening agent for foods and in the manufacture of cakes, candies, preservatives, soft drinks, alcohol and numerous other foods.

Blackstrap Molasses
This thick, dark liquid remains when the sugar has been removed from the boiled cane juice. It is used primarily as animal feed but can also be sold as syrup, to flavor rum and other foods or as an additive for ethyl alcohol.

Bagasse (baa gas)
After the juice has been extracted from the sugarcane stalk, this plant material remains. While generally burned as fuel for the mills, it could be used as a feedstock for ethanol production.

Ethanol
The increased demand for ethanol has generated interest in using U.S. sugarcane as a feedstock for producing the fuel. Sugarcane, which produces a large amount of biomass per acre in the form of bagasse and cane stalks and leaves, would be a viable feedstock for the cellulosic conversion of biomass into ethanol. Instead of having to first convert the sugarcane to sugar juice, ethanol could be produced by processing the entire plant.

USDA (2006) estimates that the cost of producing 1 gallon of ethanol from sugarcane is $2.40, which compares with $1.03 for corn wet milling and $1.05 for corn dry milling. The cost of using U.S. sugar products is even higher: $3.48 for raw cane sugar and $3.97 for refined sugar. Of the various sugar crops and products, molasses is the most cost competitive with corn.

With unique transportation circumstances and a declining sugarcane industry, Hawaii is aiming to become the first state with a sizable sugar ethanol industry. Hawaii state law now requires that at least 10 percent of all gasoline sold in the state be blended with ethanol.

Electricity
In the United States, the Clewiston Sugar Factory in Clewiston, Florida, is powered by bagasse. In Brazil, sugar and ethanol plants produce electricity by burning bagasse and cane straw in boilers to produce steam that generates power. Currently, the plants generate about 1,800 megawatts in surplus electricity, or about 3 percent of the country’s overall needs. According to UNICA (the Brazilian Sugarcane Industry Association), the sugarcane industry could generate an average of 15,000 megawatts by 2020, or enough to supply up to 15 percent of Brazil’s total electricity needs.

Exports

USDA administers two re-export programs to help U.S. sugar refiners and manufacturers of sugar-containing products compete in world markets: the Refined Sugar Re-Export Program and the Sugar-Containing Products Re-Export Program. These programs are the chief source of U.S. sugar (including beet sugar) exports, which totaled 225,000 short tons raw value (STRV) of sugar in 2010.

According to Foreign Agricultural Service (FAS) data, 167,697 MTRV, or 84 percent, of that year's refined sugar exports were shipped to Mexico, an important export destination since 2004. Other significant markets for U.S. sugar are Canada, Germany and the Netherlands.

Imports

Most U.S. sugar imports are raw cane sugar. The U.S. government places import quotas on raw cane sugar to protect U.S. consumers and sugar producers from price fluctuations in the world marketplace. The raw cane sugar quotas are allocated to 40 countries based on patterns established from 1975 to 1981. Sugar imports can increase to compensate for domestic production shortfalls.

In 2011 more than 3.7 million STRV of sugar (including beet sugar) were imported, with 1.7 million STRV, or 45 percent, coming from Mexico. The second largest source of sugar, totaling 1.5 million STRV, entered the country under tariff-rate quotas (TRQ).  

Outlook

U.S. sugar processors and producers face increasing import competition. No duties or restraints remain in effect for either Mexican sugar shipments to the United States or U.S. high-fructose corn syrup shipments to Mexico. In addition, Mexico's over-quota tariff on U.S. sugar was eliminated, as required by the North American Free Trade Agreement (NAFTA). Sugar imports will likely increase as a result of other free trade agreements, such as the Central American Free Trade Agreement/Dominican Republic (CAFTA/DR), which like NAFTA, allows sugar to enter the United States duty free.

Analysis by the Sugar and Sweeteners Team of USDA’s Economic Research Service suggests that the U.S. market will continue to depend on refined sugar imports from Mexico and Central America to meet demand.
