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.

Beet Pulp

The sugar beet industry produces considerable amounts of organic waste and by-products. Sugar beet pulp (SBP) is the residue that remains after sugar extraction. SBP is a lignocellulosic by-product of the sugar industry and generally used as animal feed at relatively low price. Instead of cattle feeding, SBP can be used as a raw material for industrial applications because it is low-cost and available in large amounts. Biomass is a clean and renewable energy source. The use of SBP for the production of ethanol, methanol, single cell protein, biofuels etc. is economically very attractive. This literature review evaluates the use of SBP as biomass.

In accordance with Nordzucker’s energy policy, Nordzucker has launched two projects to exploit the energy potential in side streams from sugar production: 1 Enhanced biogas production from anaerobic wastewater treatment with enzymatically hydrolyzed sugar beet pulp 2 Biogas production from tops and tails Before the two projects were started, the biogas potential in beet pulp and tops and tails was tested at Teknologisk Institut, Aarhus, Denmark. The biogas potential in both beet pulp and tops and tails was almost at the same level namely 324 and 313m3 (S.T.P.) CH4/t VSS (volatile suspended solids) respectively. The test also showed that app. 90% of the biogas was realized after app. 9 days. After 35 days, the degradation was completed.

Maximum Moisture Content

The sugar beet pulp from the sugar production is, thanks to the easily assimilable carbohydrate content, an important source of feed, especially for polygastric animals. Its efficiency in terms of assimilation and biological effect can be substantially improved by the addition of macroelements (Ca, Mg, P) and microelements (Zn, Co, Fe, Mn, Cu). These elements react with the sugar beet pulp compounds to form specific chelates. In order to preserve and maintain the nutritional value of the premix, the realization process involves a drying operation. In view of this, experiments have been carried out to determine the maximum moisture content that ensures preservation and optimum drying conditions. This paper presents how the percentage of micro-and macro-elements used and the drying temperature influence the drying speed of the premix

Beet Pulp

Exhausted sugar beet pulp (ESBP), a by-product of the sugar industry, has been used as a substrate to produce lactic acid (LA). Due to the fact that ESBP contains a high percentage of pectin and hemicellulose, different pretreatments were studied to solubilize them and to facilitate the access to cellulose in the subsequent enzymatic hydrolysis. Several pretreatments were studied, specifically biological, oxidant with alkaline hydrogen peroxide (AHP), and thermochemical with acid (0.25, 0.5, or 1% w/v of H2SO4). Pretreated ESBP was enzymatically hydrolysed and fermented with the strain Lactiplantibacillus plantarum for LA production. The hydrolysis was carried out with the commercial enzymes Celluclast®, pectinase, and xylanase, for 48 h. After that, the hydrolysate was supplemented with yeast extract and calcium carbonate before the bacteria inoculation. Results showed that all the pretreatments caused a modification of the fibre composition of ESBP. In most cases, the cellulose content increased, rising from 25% to 68% when ESBP was pretreated thermochemically at 1% w/v H2SO4. The production of LA was enhanced when ESBP was pretreated thermochemically. However, it was reduced when biological and AHP pretreatments were applied. In conclusion, thermochemical pretreatment with 1% w/v H2SO4 had a positive impact on the production of LA, increasing its concentration from 27 g/L to 50 g/L.

Beet Pulp

Sugar beet pulp (SBP) was used as low value adsorbent for the removal of calcium from hard water. Batch experiments were conducted to determine the factors affecting adsorption of the process such as pH value and Ca concentration. The adsorption equilibrium of Ca2+ by the SBP is reached after 100min and a pseudo second-order kinetic model can describe the adsorption process. The initial concentrations of Ca varied from 927 to 1127mgCa2+/L. A dose of 30g/L sugar beet pulp was sufficient for the optimum removal of calcium. The overall uptake of Ca ions by sugar beet pulp has its maximum at pH=8. The adsorption equilibrium data fitted well with the Langmuir adsorption isotherm equation.

Joint Treatment

The possibility of joint treatment of spent sugar beet pulp and wastewater from a sugar factory was studied in this work. Works focused on processing of spent sugar beet pulp separately or together with other substrates can be found in the literature. In the case of some sugar factories, which have spare capacity in the anaerobic reactor on an anaerobic-aerobic wastewater treatment plant, joint processing of spent sugar beet pulp and wastewater from the sugar factory might be an interesting option. The results of the operation of a pilot plant of an anaerobic reactor with a capacity of 3.5 m3 are discussed. Operation of the pilot plant confirmed the possibility of cofermentation of these materials. The organic loading rate achieved in the anaerobic reactor was higher than 6 kg/(m3·d) (COD), while more than half of the load was provided by spent sugar beet pulp. The addition of sugar beet pulp decreased the concentration of ammonia nitrogen in the anaerobic reactor and it was even necessary to add nitrogen. However, the nitrogen content in sludge water depends on the C:N ratio in the processed sugar beet pulp, therefore this knowledge cannot be generalized. About 1.5 to 2-fold biogas production can be expected from the cofermentation of wastewater with sugar beet pulp in an anaerobic reactor, compared with the biogas production from just wastewater treatment.
