Sugar Beet Pulp in the Context of Developing the Concept of Circular Bioeconomy

Abstract

The primary objective of this paper is to identify the possibilities of using sugar beet pulp as feedstock to produce a variety of added-value products. Such an application of the sugar production byproducts contributes to implementing circular bio-economy, which is a source of many economic, social, and environmental benefits. Specific objectives of this paper are: (1) Presenting the concept and meaning of circular bio-economy. (2) Characterizing properties of the sugar beet pulp from the perspective of using them as feedstock. (3) Determining the volume of production of the sugar beet pulp and the current methods of using them. (4) Determining the methods of obtaining attractive bioproducts and renewable energy from sugar beet pulp. Special attention was given to the amount of sugar beet pulp produced in Polish sugar refineries. Poland is among the European countries in which the volume of produced sugar is especially high. Therefore, the problem of appropriate waste management in the Polish sugar industry gains significant importance. The conducted literature review demonstrated that sugar beet pulp might be used as a feedstock in the production of many bio-products produced using a variety of methods.

Value Added Products Generation from Sugarcane Bagasse and Its Impact on Economizing Biorefinery and Sustainability of Sugarcane Industry

“…These challenges have forced researchers to look into other approaches for a biofuel supply that is both affordable and sustainable. Sugarcane straw, sugarcane pulp/bagasse, and sugarcane residues may be great options of feedstock for the production of second-generation (2G) biofuel (Figure 1) [2].…”

“…Sugarcane yields one of the highest amount of sugars per hectare as a commercial crop grown in tropical and sub-tropical regions that is highly productive in harvesting sun energy, atmospheric carbon dioxide, water, and nutrients, basically Nitrogen, into biomass and simple pentoses like sucrose [2]. The production of food for human consumption, animal feed, biofuels, value added products, and highly specialized commercial products can be attained with potentially and commercially profitable raw materials.…”

“…The largest producer of sugarcane in the world is Brazil (40 percent of world production). India, Thailand, China, Mexico, and Pakistan, round out the list of nations that produce sugar [2,7].…”

“…The negative perception of refined sugar being identified as a potent causative agent in lifestyle diseases like hypertension, overweight, and insulin resistance, the lack of stability in the market of refined sugar as a commodity, the impact of increasingly popular use of alternative sweeteners like high fructose corn syrup HFCS, Stevia (Stevia rebaudiana), and other high intensity sweeteners (HIS) in the food industry are just a few of the obstacles that the agribusiness continues to face [2,8].…”

Tuning Sugar Biomass Waste Conversion for the Preparation of Carbon Materials for Supercapacitors and Catalysts for Oxygen Reduction

“…It is therefore urgently necessary to develop new chemical technologies based on the use of sugar beet bagasse wastes to produce various useful products. [10,13] Traditionally, beet pulp is used for feed and used as a source of food fibers, [12] and the recent increased interest in the development of valueadded products from beet pulp has stimulated the search for new processing areas, among which is the creation of a porous Agriculture is the most massive material circulation activity of humans, with significant annual volumes of production as well as substantial amounts of waste. Transforming agricultural wastes into high-value-added products is the key to sustainable development with efficient usage of renewable resources.…”
