Nutrient characterization and bioenergy potential of common Nigerian food wastes
by Gurumwal George Longjan and Zahir Dehouche

Editor’s Comment:

 

This paper presents the results of research about the potential for recovering energy from a wide range of crop wastes in Nigeria, by using such wastes as feedstock to anaerobic digesters (AD).  Nigeria is the world’s largest producer of several types of produce, including yams, cassava (rich in starch and a source of flour), cocoyam (source of taro), and cowpeas (a herbaceous legume used as cattle feed).  Significant amounts of peanuts, plantains, corn, and pumpkin leaves are also grown in Nigeria.  In general, solid wastes from the harvesting and processing of these crops are not subject to systematic management, so the disposal of such wastes can pose risks to environmental quality and public health.  The research reported here indicates that the nutrient content that still remains in these agricultural wastes might be a significant source of energy in the form of bio-methane, up to 31 TWh per year, enough to supply up to 24% of Nigeria’s population with electricity. This paper expands on the growing body of knowledge about methods of managing food wastes to minimize disposal and optimize recovery of the intrinsic value of crop residues.

Does reducing food losses and wastes in sub-Saharan Africa make economic sense?
by Emerta Aragie, Jean Balié, and Cristian MoralesOpazo

 

Editor's Comment:

 

This volume of WMR contains eight top class manuscripts in a broad range of areas. The editorial captures the latest topic of Circular Economy and explores, among others, the impact of resources import ban by China. The waste collection and management fee structure determines waste collection efficiency and this subject is discussed in the paper from China. Then there is the waste management scenario paper from Israel. Another important area that receives attention and many papers these days is the use of GIS-based waste site determination Here we published another GIS-based paper which explores the waste flow system for Construction and Demolition waste in Brazil. Of course, in my opinion, the paper of my choice for June 2018 is the food waste paper from sub-Saharan countries.


Food waste is a serious issue and is universal in nature. The wastage is evident not only in developed nations but in developing countries too. The wastage could range from 10-40% depending on the stages of the food processing chain. The wastage directly corresponds to the food insecurity situation which is recognized as serious in many nations.


Authors report a loss of 28-38% in the processing of food in sub-Saharan countries which is considered an important issue for developing countries. They also postulated that farm incomes would increase by 20% if the avoidable losses and waste were recovered. These results are troublesome given the level of poverty and food insecurity in these countries and suggest inefficient and unsustainable use of natural resources (water and cropland) associated with the Food supply chain losses.


There is a need to highlight food wastage issue which is becoming more evident in developing countries and this paper is just one example.
