“…Food waste can be fed to livestock other than pigs, including poultry, fish, and ruminants (Angulo et al., 2012, Boushy and van der Poel, 2000, Cheng et al., 2014). This study focussed on the use of municipal waste as pig feed because they have a long history of recycling waste into animal products (Fairlie, 2010), and because there are human health concerns with feeding food wastes which contain animal products to other livestock species, notably ruminants.…”

The disposal of food waste is a large environmental problem. In the United Kingdom (UK), approximately 15 million tonnes of food are wasted each year, mostly disposed of in landfill, via composting, or anaerobic digestion (AD). European Union (EU) guidelines state that food waste should preferentially be used as animal feed though for most food waste this practice is currently illegal, because of disease control concerns. Interest in the potential diversion of food waste for animal feed is however growing, with a number of East Asian states offering working examples of safe food waste recycling – based on tight regulation and rendering food waste safe through heat treatment. This study investigates the potential benefits of diverting food waste for pig feed in the UK. A hybrid, consequential life cycle assessment (LCA) was conducted to compare the environmental and health impacts of four technologies for food waste processing: two technologies of South Korean style-animal feed production (as a wet pig feed and a dry pig feed) were compared with two widespread UK disposal technologies: AD and composting. Results of 14 mid-point impact categories show that the processing of food waste as a wet pig feed and a dry pig feed have the best and second-best scores, respectively, for 13/14 and 12/14 environmental and health impacts. The low impact of food waste feed stems in large part from its substitution of conventional feed, the production of which has substantial environmental and health impacts. While the re-legalisation of the use of food waste as pig feed could offer environmental and public health benefits, this will require support from policy makers, the public, and the pig industry, as well as investment in separated food waste collection which currently occurs in only a minority of regions.

“…Considering the nutritional value found for fruit and vegetable waste, it was proved that this product might be considered as a potential alternative for animal feeding. Angulo et al (2012) evaluated the use of fruit and vegetable waste from market place as feedstuff for diets of lactating Holstein cows with an emphasis on milk yield and quality. The wastes mixture was included in 0, 6, 8, 12, and 18% of the concentrate and these wastes could be a good alternative feedstuff, without detriment in the milk yield and with improvement in the milk quality.…”

The production of food waste covers all the food life cycle: from agriculture, up to industrial manufacturing and processing, retail and household consumption. In developed countries, 42% of food waste is produced by households, while 39% losses occur in the food manufacturing industry, 14% in food service sector and remaining 5% in retail and distribution. Increasingly, industrial ecology concepts such as cradle to cradle and circular economy are considered leading principle for eco-innovation, aiming at "zero waste economy" in which waste are used as raw material for new products and applications. The large amount of waste produced by the food industry, in addition to being a great loss of valuable materials, also raises serious management problems, both from the economic and environmental point of view. Many of these residues, however, have the potential to be reused into other production systems, trough e.g. biorefineries. The present work focuses on the use of food waste coming from food manufacturing (FWm). Through extensive literature review, the authors present feasibility and constraints of applying industrial symbiosis in recovering waste from food processing, focusing on recycling (excluding energy recovery) of the solid and liquid waste from food processing industry. The main uses of functional ingredients derived from this transformation are presented and discussed, highlighting mainstream sectors of application, e.g. in the nutraceutical and pharmaceutical industry.

“…Although a number of studies attempted to use FVD as a feed ingredient in animal diet [5], FVD is a relatively new class of feed ingredient potentially rich in vitamins, minerals, and phytonutrients which may provide additional benefits for animals beyond a simple feed ingredient. According to the experimental data obtained over two years in our laboratory [6,7], FVD is high in moisture (85% to 88%) and soluble sugars (44% to 63%; dry matter [DM] basis), which speed up the microbial deterioration and therefore causes environmental problems [6,7].…”

Objective: Our recent series of laboratory- and large-scale experiments confirmed that under aerobic and anaerobic conditions, sodium metabisulfite (SMB) was effective in preserving nutrients and antioxidant capacity of highly perishable fruit and vegetable discards (FVD). Hence, the purpose of this study was to examine how partial inclusion of SMB-treated FVD in total mixed ration (TMR) influences in vitro ruminal fermentation, whole-tract digestibility, nitrogen metabolism, blood metabolites, and voluntary feed intake of sheep.Methods: The FVD were mixed thoroughly with 6 g SMB/kg wet biomass and kept outdoors under aerobic conditions for 7 days. Four TMRs including four levels of SMB-treated FVD (as-fed basis) at 0%, 10%, 20%, and 30% (equaling to 0%, 1.9%, 3.8%, and 5.7% on dry matter basis, respectively), were prepared as replacement for corn grain. The ruminal fermentation metabolites were studied using an in vitro gas production test. Four mature male Corriedale sheep were assigned at random to the 4 diets for two separate sub-experiments; i) digestibility trial with four 21-d periods, and ii) voluntary feed intake trial with four 28-d periods.Results: Inclusion of SMB-treated FVD in the TMR tended to quadratically increase partitioning factor. No effect was seen on total-tract digestibility of organic matter, ether extract, crude protein, and acid detergent fiber, except for neutral detergent fiber digestibility that tended to linearly increase with increasing SMB-treated FVD in the TMR. The progressive increase of FVD preserved with SMB in the diet had no effect on nitrogen metabolism. Treatment had no effect on serum antioxidant capacity and blood metabolites assayed. Voluntary feed intake was not impaired by inclusion of SMB-treated FVD in the TMR.Conclusion: It appears that FVD preserved with SMB can be safely incorporated into TMR as replacement of corn grain without impairment of nutrient metabolism and feed intake.
