Atlas of MSW landfills and dumpsites in developing countries

[en] This paper presents the results of a six-year experience in collecting data on landfills and dumpsites in developing countries. Information such as the position of a landfill, its size and the way it is managed are gathered in a database. The characterisation of wastes is also performed. Finally the actions taken or to be taken on each site are summarized. The purpose of such a project is to keep in memory all the information available about the main landfills and dumpsites in developing countries. This allows the identification and the management of their negative impacts on the environment. Furthermore, this tool will be of first help to set up proper rehabilitation projects. At present time, information about 85 landfills from 13 countries has been collected. The main partners of this project are Tunisia, Haiti, Senegal, Burkina Faso and Cuba. Besides those factual partnerships, new collaboration projects are being discussed with other countries such as Guinea. This work has already received the positive support of people involved in waste management in West Africa.The Atlas of MSW landfills and dumpsites in developing countries is published on the Internet (http://www.ulg.ac.be/cwbi/index.htm). Thanks to the support of the IEPF (Institut de l'Energie et de l'Environnement de la Francophonie / Institute for Energy and Environment in French talking Countries; IEPF is a member of AIF), it will be entirely updated and diffused on a broad range. This includes development of a new relational database and Internet site and the edition of a paper version of the Atlas.info:eu-repo/semantics/publishe

Landfill management in Africa

[en] Landfill management is an important matter to study in order to set up techniques respectful of the environment. Before any suggestions of management solutions, behaviour of landfills has to be characterised. This is necessary to predict future interactions between a landfill and the neighbourhood, and to estimate the landfill lifetime. Water is one of the most important parameter implied in the biological degradation of refuse, which is a substantial source of pollution. Therefore, this parameter is characterised in terms of quantitative and qualitative data. A relationship between climatic conditions, one of the main source of water, and possible evolution of landfills is propounded.info:eu-repo/semantics/publishe

Chemical Fingerprint and Anti-Sickling Activity of Rosmarinic Acid and Methanolic Extracts from Three Species of Ocimum from DR Congo

peer reviewedThe aim of this study was to characterize the polyphenolic composition by determination of chemical fingerprints of Methanolic extracts of Ocimum canum Sims, Ocimum basilicum L. and Ocimum gratissimum L. from Democratic Republic of Congo and to compare their antisickling activity of that of rosmarinic acid, the major compound to those of methanolic extracts. Phytochemical analysis performed by TLC and HPLC analysis, showed that rosmarinic acid is the most abundant phenolic acid in these Ocimum species according to the following order O. basilicum L., O. gratissimum L. and O. canum Sims. Methanolic extracts of these three species and pure rosmarinic acid showed significant antisickling activities with minimal concentration of normalization values of 0.18 ± 0.03, 0.23 ± 0.04, 0.26 ± 0.04 and 0.31 ± 0.05 mg/mL for rosmarinic acid, O. basilicum L., O. gratissimum L. and O. canum Sims methanolic extracts respectively. The antisickling activity order is the same as that of the rosmarinic acid content, indicating that this polyphenolic acid would be among the main active molecules in these extracts

Atlas of MSW landfills and dumpsites in developing countries

[en] This paper presents the results of a five-year experience in collecting data's on landfills and dumpsites in developing countries. At present time, information about 81 landfills from 12 countries has been collected. The main partners of this project are Tunisia, Haiti, Senegal and Burkina Faso. Besides those factual partnerships, new collaboration projects are being discussed with Guinea, Cuba, Vietnam and Kuwait. The data are gathered in the Atlas of MSW landfills and dumpsites in developing countries and are published on the Internet (http://www.ulg.ac.be/cwbi/index.htm). The purpose of such a project is to keep in memory the existence and characterisation of the main landfills and dumpsites in order to allow the identification and the management of their negative impacts on the environment. Moreover, it will be useful to set up proper rehabilitation projects.
