Exploring insect farming as a sustainable solution to organic waste disposal and animal feed production.
The rising costs and limited access to high quality animal feeds constrain the development of the poultry and livestock sectors in the Caribbean and threatens food security in the region.
There is also a growing problem of managing organic waste from farms, markets, restaurants, hotels and food manufacturers that create health, environment and climate risks, the FAO says.
In examining solutions to these challenges, the Food and Agriculture Organization of the United Nations (FAO), in collaboration with Fera Science Ltd., recently completed a survey of organic waste across Barbados, Jamaica, Grenada, and Trinidad and Tobago.
The study assessed the potential of insect farming as a solution to the twin problem of increasing volumes of organic wastes, and the lack of stable access to affordable animal feed.
Insect farming is widely regarded around the world as one of the key solutions to reducing waste in the environment and creating sustainable sources of animal feed.
In this process, selected insect species efficiently convert organic waste (biomass), through their natural ability to upcycle waste material, into high-quality products, suitable for agriculture and animal feed industries.
The black soldier fly larvae are the main insects being farmed. It is one of nature’s recyclers, and rapidly consumes wastes and turns it into larvae that are enjoyed by chickens and fish as a natural feed.
Insect farming provides a sustainable solution that complements existing community vermi-composting schemes and enables the creation of fertilisers, animal protein feed, oils, and new valuable products by making better use of organic wastes.
“Waste materials identified in the study could sustain the growth of enough insects to achieve 50% inclusion into poultry feed for the entire poultry population in the countries studied,” Renata Clarke, FAO Caribbean Sub-regional Coordinator said.
“This would reduce the reliance on tonnes of soy and other costly and unsustainable sources of protein such as fishmeal from ocean ecosystems. Commercial development of new sources of safe and traceable proteins is essential to meet the needs of growing populations, especially with increased consumption of meat, fish and eggs.”
Clarke further said that the Caribbean poultry sector would become less vulnerable to external shocks, more environmentally friendly and create new economically viable feed businesses accessible by small-scale entrepreneurs and communities.
As an introduction to this innovation, FAO, Fera, and the University of the West Indies are developing a regional pilot project to showcase the value of insect farming and provide the catalyst for a series of community projects focused on creating sustainable animal feed from organic wastes.
Damian Malins from Fera Science Ltd. said: “We are very excited to be working with FAO and the University of the West Indies, to establish insect farming in the region.”
Malins said the pilot project will engage farmers, communities, ministries and a range of private sector partners to create a best practice for future insect farmers.
“It will also create a community solution to reducing wastes and creating an affordable, sustainable animal feed.”
The findings of the FAO study will be discussed with all interested stakeholders in a virtual forum in March with implementation of the pilot project set to begin by mid-year.
