Plenary speakers

Mrs Zuraida Binti Kamaruddin

Malaysian Minister of Housing and Local Government

Zuraida is the current Malaysian Member of Parliament for the constituency of Ampang which is located in the industrialised Malaysian state of Selangor. She is a current member of the Malaysian Cabinet as the Minister of Housing and Local Government since May 2018 while also being the Women’s Chief of the Pakatan Harapan (PH) ruling coalition.
As a minister of the historic newly elected Malaysian government, Zuraida has started to implement reforms to upgrade the living conditions of Malaysians of the middle class and particularly those belonging to the bottom 40% (B40) of household income earners who only earn 940 USD and below by initiating various schemes to increase the supply of affordable and comfortable housing. Zuraida is also a champion of environmental issues, especially pertaining to waste management which falls under the ambit of her Ministry. In line with the new Malaysian government’s direction of balancing economic growth with environmental protection, Zuraida has restructured the SWCorp, which is a government-linked corporation tasked with solid waste management and public sanitation to become more efficient, integrated and provide better customer satisfaction. Her Ministry is also responsible (via SWCorp) in enforcing laws related to solid waste management and public sanitation. It is also tasked with public engagement and community education such as introducing 3R modules in pre-schools to promote recycling with the aim of increasing the recycling rate to 30% by 2020. Despite these efforts, the never-ending problem of overflowing landfills has caused Zuraida to implement Waste to Energy (WTE) initiatives where solid wastes are now being utilised to generate electrical energy. This will not only reduce the operating cost of solid waste management but also generate revenue through environmentally friendly energy generation.
