Abstract: The forming background, properties and classification of eco-cement as well as it’s characteristics are systematically expatiated in this paper and the application and research progress of eco-cement in and abroad are introduced. The domestic research status of eco-cement and some presently existing problems are analyzed and discussed. It’s believed that there are good prospect of eco-cement in our country, much more attention should be paid on the problem which conclude security production, exhaust gas emission and environmental pollution control regulations of the eco-cement production. In the development of eco-cement industry, it’s necessary to consider the factors of environment and city construction for the industrial plan. Furthermore, the performance and application field of eco-cement still have to be improved.

Abstract: Industry has become an essential part of modern society, and waste production is an inevitable outcome of the developmental activities. A material becomes waste when it is discarded with impunity and may pose a potential hazard to the human health or the environment (soil, air, waste) when improperly treated, stored, transported or disposed off or managed. In other words, scheduled waste contributes a major share towards environmental degradation. Scheduled and hazardous waste is the most difficult waste to be managed due to the dangerous elements not only for the environment but also for public health. In Malaysia, in the last two decades, the waste management has been a major concern. Malaysia has developed a comprehensive set of legal provisions related to the management of toxic and hazardous wastes. In this work, an evaluation of the scheduled waste management in Malaysia is made: in term of legislation framework, type of wastes and waste volume production.
