Integrated Recovery

Concerns regarding the overconsumption of natural resources has provoked the recovery of biopolymers from food processing biomass. Furthermore, the current market opportunity for pectin in other areas has increased, necessitating the search for alternative pectin resources. This is also a step towards the sustainable and circular green economy. Mango peel is the byproduct of agro-processing and has been used for high value-added components such as polysaccharide biopolymers. Pectin derived from the peel is yet to be exploited to its greatest extent, particularly in terms of its separation and physiochemical properties, which limit its applicability to dietary fiber in culinary applications. The functionality of the mango peel pectin (MPP) strongly depends on the molecular size and degree of esterification which highlight the importance of isolation and characterisation of pectin from this novel resource. This article therefore provides a useful overview of mango peel as a potential biomaterial for the recovery of MPP. Different extraction techniques and the integrated recovery were also discussed. The utilisation of MPP in different industrial schemes are also detailed out from different perspectives such as the pharmaceutical and biotechnology industries. This review convincingly expresses the significance of MPP, providing a sustainable opportunity for food and pharmaceutical development.

Regulation Costs

The authors use a method of matched-plant comparisons between food processing firms in Germany, Italy, Northern Ireland, and the Republic of Ireland to investigate the relationship between environmental regulation and company competitiveness across the European Union. Comparative competitiveness was indicated by measures of value-added per employee, physical productivity, export share, and employment growth. The cost of water supply (public or well), effluent treatment (in-plant treatment and/or sewerage system), and disposal of sludge and packaging were also compared. Total environmental costs in Germany, Italy, and Ireland were small: usually less than 1% of turnover. Compared with the Irish firms, German companies had relatively high environmental costs as well as productivity levels. There was, however, a lack of a clear relationship between company competitiveness and the size of regulation costs: in Ireland and Italy environmental costs were similar but German firms had much higher productivity; compared with German counterparts, Italian firms had lower environmental costs but higher productivity.

Biotechnology is one of the fields highlighted by the Economic Committee as an area of high value-added technology which could be developed in Singapore. The recommendation of the Economic Committee was that the venture capital industry be developed to aid in attracting young foreign technological firms to Singapore. Biotechnology includes the areas of pharmaceuticals, chemicals, food processing and agro-technology. A number of local biotechnology businesses have sprung up. This is an interesting phenomenon since biotechnology is difficult ground for small firms to be engaged in. It is usually associated with a long lag time between the development and the actual introduction of the product into the market-place, a need for large sums to be invested in research, and a short product life span, amongst other disadvantages. In an environment where enterprise is only currently being encouraged and entrepreneurship being nurtured, one would not have expected local entrepreneurs to venture into biotechnology. It would therefore be of interest to examine these businesses to see if there are any unique problems that they face by operating in Singapore. This paper proposes to examine the problems encountered by these local firms. Some of the problems ascertained through interviews with local firms concern financing and government funding, and availability of trained staff.

Municipal Wastewater Treatment Plants

The Circular and Green Economy principles is inspiring new approaches to municipal wastewater treatment plants (MWWTPs) design and operation. Recently, an ever-growing interest is devoted to exploring the alternatives for switching the WWTPs from being able to ‘simply’ removing contaminants from water to biorefinery-like plants where energy and material can be recovered. In this perspective, both wastewater and residues from process can be valorised for recovering nutrients (N and P), producing value added products (i.e. biopolymers), energy vectors and biofuels (i.e. bio-H2, bio-CH4 and bioethanol). As an additional benefit, changing the approach for WWTPs design and operation will decrease the overall amount of landfilled residues. In this context, the present research is aimed at evaluating the CH4 production potential of MWW screening units’ residues. While such a stream is typically landfilled, the expected progressive increase of biodegradable matter content due to the ban on single-use plastic along with the boost of bioplastics makes the investigation of different biochemical valorisation routes more and more interesting from an environmental and economical perspective. Thus, a full-scale data collection campaign was performed to gain information on screening residues amount and properties and to analyse the relationship with influent flowrate. The most relevant residue properties were measured, and lab-scale tests were carried out to evaluate the bio-CH4 potential.

Abstract Background Xylose is a most prevalent sugar available in hemicellulose fraction of lignocellulosic biomass (LCB) and of great interest for the green economy. Unfortunately, most of the cell factories cannot inherently metabolize xylose as sole carbon source. Yarrowia lipolytica is a non-conventional yeast to produce industrially important metabolites, and it is able to metabolize a large variety of substrates including both hydrophilic and hydrophobic carbon sources. However, Y. lipolytica lacks effective metabolic pathway for xylose uptake and only scarce information is available on utilization of xylose. For the economically feasible of LCB-based biorefineries, effective utilization of both pentose and hexose sugars is obligatory. Results In the present study, succinic acid (SA) production from xylose by Y. lipolytica was examined. To this end, Y. lipolytica PSA02004 strain was engineered by overexpressing pentose pathway cassette comprising of xylose reductase ( XR ), xylitol dehydrogenase ( XDH ) and xylulose kinase ( XK ) gene. The recombinant strain exhibited a robust growth on xylose as sole carbon source and accumulated SA (3.8 g/L) with a yield of 0.19 g/g in shake flask studies. Substrate inhibition studies revealed a marked negative impact on cell growth and product formation above 60 g/L xylose concentration. The modelling based on inhibition kinetics revealed that Aiba model showed better fit with experimental data, which resulted the correlation coefficient (R 2 ) of 0.82 and inhibition constant (K I ) 88.9 g/L. The batch cultivation of recombinant strain in bioreactor resulted in a maximum biomass concentration of 7.3 g/L and SA titer of 11.2 g/L with the yield of 0.18 g/g. Similar results in term of cell growth and SA production were obtained with xylose-rich hydrolysate derived from sugarcane bagasse. The fed-batch fermentation yielded biomass concentration of 11.8 g/L (OD 600 : 56.1) and SA titer of 22.3 g/L with a gradual decrease in pH below 4.0. Acetic acid was obtained as a main byproduct in all the fermentations. Conclusion The recombinant strain displayed potential bioconversion of xylose to succinic acid. Further this study provided a new insight on conversion of LCB into value-added products. To the best of our knowledge, this is the first study on SA production by Y. lipolytica using xylose as a sole carbon source.

The objective of the paper is identifying the main organic food sales channels from processing companies and attempting to determine their influence on organic food processing. Recently, the dynamic development of organic farming and its market has been observed. Nevertheless, the elements of this market show a number of weaknesses. One of the weakest links of the studied market is the processing of organic food, which bears a high transaction cost resulting from, among others, low distribution development. The paper presents the results of an inquiry research carried out in the first half of 2019 on 55 organic food processors. Conducted research shows that the production structure of the examined companies, mainly focused on fruit, vegetable and cereal products, is only partly adjusted to consumer expectations, who increasingly prefer organic dairy and meat. The main distribution channel is sales to small retail outlets. Wholesale trade came second, although still too underdeveloped, to assure effective products flow from processors to retail. More than half of the studied processors sell their products abroad, mainly to EU countries, North America and Asia. However, it is low-processed products, which are mostly exported. This is an unfavourable phenomenon from a value-added generating perspective.

This short review analyzed the recent trend towards, progresses towards the preparation of chemicals of, and value-added biomaterials from marine macroalgae resources, especially green seaweeds and their derived ulvan polysaccharides for various applications. In recent years, ulvan both in pristine and modified forms has gained a large amount of attention for its effective utilization in various areas due to its unique physiochemical properties, lack of exploration, and higher green seaweed production. The pristine form of ulvan (sulfated polysaccharides) is used as a bio-component; food ingredient; or a raw material for the production of numerous chemicals such as fuels, cosmetics, and pharmaceuticals, whereas its modified form is used in the sector of composites, membranes, and scaffolds, among others, because of its physicochemical properties. This review highlights the utilization of green seaweed and its derived ulvan polysaccharides for the preparation of numerous chemicals (e.g., solvents, fuel, and gas) and also value-added biomaterials with various morphologies (e.g., gels, fibers, films, scaffolds, nanomaterials, and composites).
