Enzyme assisted juice extraction from Dacryodes macrophylla as a potential bio-resource for wine production.

Atom fruit () is a Non-timber Forest Product (NTFP) that comprises a large seed, thick pulp, and a thin hard outer covering. The structural component of its cell wall and thick pulp make it difficult in extracting the juice. Also, fruit is greatly underutilized, therefore the need to process and transform it into other value-added products.

Effect of Modified Greenhouse Drying Technology on the Physicochemical Quality of Cameroonian Cocoa Beans.

Several benefits give credence to the importance of maintaining the reference values of the physicochemical properties of cocoa beans at all stages along the cocoa chain. Every drying method confers significant effects on quality with implications on demand and prices. In this work, the modified greenhouse dryers were tested as potential equipment for the production of high quality cocoa beans.

The removal of arsenic from solution through biochar-enhanced precipitation of calcium-arsenic derivatives.

Arsenic (As) pollution remains a major threat to the quality of global soils and drinking water. The health effects of As pollution are often severe and have been largely reported across Asia and South America. This study investigated the possibility of using unmodified biochar derived from rice husk (RB) and aspen wood (WB) at 400 °C and 700 °C to enhance the precipitation of calcium/arsenic compounds for the removal of As(III) from solution.

Quantifying greenhouse gas emissions from municipal solid waste dumpsites in Cameroon.

Open dumpsites that receive municipal solid waste are potentially significant sources of greenhouse gas (GHG) emissions into the atmosphere. There is little data available on emissions from these sources, especially in the unique climate and management of central Africa. This research aimed at quantifying CH, NO and CO emissions from two open dumpsites in Cameroon, located in Mussaka-Buea, regional headquarters of the South West Region and in Mbellewa-Bamenda, regional headquarters of the North West Region.

Greenhouse gas and ammonia emissions from production of compost bedding on a dairy farm.

Recent developments in composting technology enable dairy farms to produce their own bedding from composted manure. This management practice alters the fate of carbon and nitrogen; however, there is little data available documenting how gaseous emissions are impacted. This study measured in-situ emissions of methane (CH), carbon dioxide (CO), nitrous oxide (NO), and ammonia (NH) from an on-farm solid-liquid separation system followed by continuously-turned plug-flow composting over three seasons.
