sectors of meat, fish, dairy, wine and vegetables at the European level [17]. Three
main issues that were supposed to be addressed by this initiative were regulatory
issues, technological aspects, market potential and requirements of agro-food
industrial wastes to propose a global R&D strategy.
REFRESH is a European Union H2020 funded research project involving 26 part-
ners from 12 European countries and China with the objective of significantly reduc-
ing the food wastage at all steps in the agri-food processing chain and also maximiz-
ing the valorization to beneficial products [18].
SIVEQ short for Sistema Integrato per la Valorizzazionedelle Eccedenze Alimenta-
rinel Quartiere, “Integrated system for the valorization of surplus food in the district”
in English, is a data acquisition platform with a web interface which aims for the
redistribution of food before it turns unfit for human consumption [19] using a sys-
tematic approach of IoT and Big Data Analysis [20].
A collaborative project called “New Advances in the Integrated Management
of Food Processing Waste in India and Europe” (NAMASTE-EU) between India
and European Union (European Commission, 2010–2013) which is worth €1.5 M
has proven to be effective. The project in co-ordination between Department of
Biotechnology, Government of India and seven partners from six European coun-
tries including three companies is focusing on valorization of citrus byproducts,
mango, pomegranate, rice bran and wheat bran processing.
Many worldwide initiatives have brought the importance of agri-food valorization
into limelight.

Composition-Based Solutions and Approaches
Majority of AFWs contain starch, cellulose, hemicelluloses, pectin, soluble sugars
such as glucose, fructose and sucrose, proteins, lipids [21], lignin and antioxidants
[6]. The valorization approach and application largely depend on the initial chem-
ical constituents of AFW’s. Fatty acid methyl esters are the common biochemicals
recovered from wastes rich in lipids. Extraction of organic acids from volatile fatty
acids [22] is also possible. High cellulosic wastes or sugars have the potential for con-
version into ethanol, butanol, acetone, etc., via fermentation and bioactive peptides
can be recovered from high-protein wastes.
The current chapter will delve into different approaches of agri-food valorization
with applications in biochemicals and bioplastics. Biological solutions involving
production of biochemicals, enzymes, food/feed supplements, thermochemical and
microbial solutions of generating energy have also been dealt. Cursory reference
has also been made with respect to applications in food, feed supplements, cos-
metics, food pharmaceutical industries and also for fuels and energy employing
thermochemical and microbial methods.
