Reusing and Recycling Potatoe Waste

The recovery of food from Food Industry waste will become more and more attractive as food prices increase and per capita availability decreases.

In general technology is already available to recover value but the viability limits what is done. This is an interesting approach to improve viability by addressing the logistics of handling waste.

THINK-EAT-SAVE Food Waste Enjoying Growing Attention

I have written on Food Waste now and then as it's clearly a part of the food supply system where the world can grow food availability using existing technology.

Now a UNEP/FAO lead campaign, supported by initiatives such as WRAP, has been launched.

Think-Eat-Save and the slogan “Reduce Your Foodprint” seem to indicate that it is focussed on the consumer, but the information on the site is not limited to the household. The initiative seems to be focussing on the complete food chain.

There is already a wealth of information here, presented in a very readable way, and there are indications of actions to promote awareness and action.

Think-Eat-Save rests on four pillars

Awareness raising on the impact of, and solutions for food loss and waste.

Collaboration and coordination of world-wide initiatives on food loss and waste reduction.

Policy, strategy and programme development for food loss and waste reduction.

Support to investment programmes and projects..

The Food Waste Opportunity

When the Institute of Mechanical Engineers publishes a report on solving the expected world food shortage by reducing loss, you begin to realise this is a very widely recognized problem or opportunity. I already published a paper on this titled Waste in the food value chain: Issues and opportunities in sub-Saharan Africa in 2011, which also highlighted the wasted inputs required to produce the wasted food.

Most of the solutions are not to do with mechanization, automation or new devices. Cereals lost to poor storage in the third world environment need better management of existing systems and simple waterproofed structures. Losses in the first world retail system are more strongly linked to the need to change consumer behaviour, diet, obesity, visual standards, kitchen control, expiry dates etc than to research new technologies.

The report has some interesting data that bears repeating

  • Half the food that is grown in the world is lost and not eaten
  • 3 calories of energy are required to produce 1 calorie of food energy in the form of cereals
  • 30 calories of energy are required to produce 1 calorie of food energy in the form of bee
  • 50% of the energy input to wheat is required for fertilizer and pesticides
  • 70% of water use is by agriculture
  • Some thoughts after reading this: the food we do eat uses twice as much inputs than it would seem, the waste is mainly not on the field where it would could at least compost and fertilize but is increasingly in urban areas where it unnecessarily loads the waste disposal system.

    PROCESSING PINEAPPLE PULP INTO DIETARY FIBRE SUPPLEMENT – FREE ONLINE PAPER

    The article by N Ackom and K Tano-Debrah in the latest edition of AJFAND Online presents a well explained and investigated process to produce a pineapple fibre for use in food formulations. The study at University of Ghana, Lagon was practical and produced fibre products that were used to produce muffins and biscuits which were acceptable to consumers. The corresponding author can be contacted at newusie@yahoo.co.uk.

    This process addresses the fourth level in the EPAs Food Recovery Heirachy, ie develop an industrial use for the waste food. The EPAs Food Recovery Heirachy puts feeding animals as third after reduce loss and feed people, the first 2.

    Solving Factory Waste Through Extraction of Valuable Chemicals

    At first sight it seems like a good idea to add value to waste strems in the food processing industry.

    click the image to visit the website

    However, as the project leader says this is not rocket science. The composition of waste streams is generally well known and the technology to extract valuable components already established.It's naive to think companies are paying to dispose of waste streams that contain valuable chemicals which they could be easily extracting and selling.

    Many waste streams are actually sold for other purposes such as animal feed and compost while many are already the source of high value chemicals such as essential oils and nutritional supplements. Waste streams have also been used for centuries to produce alternate energy.

    Manufacturing companies focus strongly on waste and are just as capable of investigating such opportunities as are researchers.The issue is the financial viability of any particular process and the potential to set up all the players in the supply chain to ensure its sustainable operation.

    EU Food Waste Briefing

    The ACP-EU has recently held on of its rural development briefing on Food Waste.

    click the image to visit the website

    Around one third of all food is wasted which is already frightening enough but with the new concern on climate change it becomes even worse. The food wasted produces emissions in production and disposal for food which is just not used.

    This document presents links to a number of resources which allow the reader to understand the principles but through references to dig deeper into the issues.

    Waste & Over Eating vs Need & Malnutrition

    The work in the United Kindom on waste in the food system has lead to an intriguing, data rich report which is available on the WRAP website.

    Taking the information of how much food is wasted from this report, with the post on excessively nutritious foods and Michele Obama’s work with the the food industry to reduce the energy content in the food they sell together surely indicates a process that should start to redistribute calories.

    Maybe some more about this in future posts.

    Improving Profitability By Using Byproducts & Waste

    Published by under .Agribusiness

    We often focus on reducing ingredient costs and increasing efficiency but sometimes miss other opportunities to reduce cost and increase income. The stories linked below give some examples of the kind of thoughts we should be having.

    Basically they focus on utilising by products and waste – the point just needs to be made that these should only get focus once they have been minimised through process optimisation and management.

    Mali’s Mangos

    Published by under Development,Enterprises,Waste

    This image and text identifies the problem of the mango resource in Mali. It is one of a series of 10 pictures assembled by the BBC describing various aspects of the mango and its contribution to livelihoods in Mali.

    The text reads:

    The simplicity of the mango business is a problem. Mali is one of West Africa’s biggest producers, with around 1.2m sq km under cultivation – 50% of which is exported.

    But in years when the rains are poor the mangos are scarce, and in years of plenty the fruit rots on the trees or is eaten by animals.

    “Of course there is waste, and the price falls when we have too many mangos. We need to get better organised, and look further than Sibi for markets,” says local official Dioma Doumbia.
