Recovery of plastic bottles for recycling…
• Plastic represents more than 20% of waste
production and two thirds are plastic bottles
• The development of a policy framework for the
management of plastic packaging material and
hazardous waste for Jamaica (2001)
• There was an estimated consumption of 246 millions
Pet beverage containers in Jamaica in 2000
• Our assumption of 6% of Jamaicans generates one
plastic bottle per day, this gives you about 52 millions
per year

Theoretical and conceptual framework
• Project implementation was based on the
Voluntary Compliance Approach
• Social and psychological theories or behavioural and
situational theories to explain responsible environmental
behaviour
• Attitudes – Behaviour
• Information Integration theory in early 1970s (Norman
Anderson, 1971)
• Value and weight of new information in changing attitudes • The theory of Reasoned Action (Fishbein and Ajzen 1975)
• Behavioural intent shapes behaviour

Theoretical and conceptual framework
• Theory of Planned Behaviour (Fishbein and
Ajzen 1980, 2005)
• Perceived behavioural control which “refers to
people’s perception of the ease or difficulty of
performing the behaviour of interest” (Ajzen
1991:183)
• The theory of responsible environmental
behaviour in the early 1970 by the
Environmental Movement

Theoretical and conceptual framework
• Increase of knowledge and change of attitudes do not
automatically lead to behaviour change
• Behaviour change results from a sense of empathy and
concern, a sense of ownership and a sense of
empowerment
• Locus of control, environmental sensitivity, knowledge of environmental action and strategies, skill in environmental
action and strategies
• Within the context of this study, responsible environmental behaviour was caused by a multiplicity of factors.
• Responsible environmental behaviour derives from
general environmental values and attitudes, situational
factors and psychological factors

• In order to achieve greater accuracy and representativeness of the student population, it was decided to use stratified sampling, spatial sampling and simple random sampling procedures to identify and select the respondents.

• The questionnaire collected empirical data on
• Demographic characteristics of the students and childhood experience, • Educational backgrounds, attitudes and general knowledge of the environment,
• Generation of plastic bottles on the UWI Mona Campus,
• Issues of proper disposal of plastic bottles and responsible environmental behaviour.

Some findings
• More than 400 lbs. of plastic bottles and containers were collected every week by Protect the Environment Trust (PET). • The level of compliance in terms of solid waste separation at source was about 95% on the Halls of residence and 90%

campus wide.
• The sample size consisted of 61% females and 39% males
