• Tidak melakukan pembakaran sampah secara terbuka;
Water Consumption and Conservation
The Company uses water in the production process in its daily operational activities, particularly for spraying pipes coming out from the furnace in quenching and descaling processes; NDT and Hydrotest processes; surface treatment of pipes and couplings;
and pipes cleaning. In 2020, the Company conducted several water conservations, namely:
• Utilizing rainwater for quenching and descaling of pipe from the furnace;
• Using the closed loop system for quenching in the Heat Treatment process;
• Recycling water in the NDT and hydrotest processes.
Air Monitoring and Management
The Company strives to monitor and manage air quality to realize its concern for the continuity of life and health of living things.
ozone layer depletion. While no particular efforts have been made to measure potential emission of ozone-depleting substances from production activities, the Company carried out efforts to reduce the production of gases. The efforts made by the Company in 2020 are:
• Increasing production efficiency through heat treatment of pipes, in which refractory ceramic is used for the hardening and tempering furnace;
• Converting the main source of energy from diesel fuel to natural gas since 2005;
• Installing scrubber in the electroplating chimney to reduce air pollution;
• Monitoring the source of gas emission at 28 production locations every 6 months and mobile gas emission every year;
• Stop burning waste in open air;
• Melakukan program Pengurangan Green House Gas, melalui : o Penanaman pohon oliana, mangga dan angsana yang
terbukti mampu mengurangi polusi udara dan menyerap CO;
o Penggunaan refigerant yang ramah lingkungan.
Sistem Pengelolaan Limbah B3
Perseroan memiliki konsekuensi menghasilkan limbah bahan berbahaya dan beracun (B3) dari hasil produksi sebagai Perseroan yang bergerak di industri minyak, gas bumi dan pertambangan.
Dalam hal penanggulangan pengelolaan B3, Perseroan mengacu pada sistem pengelolaan khusus sebagaimana diatur dalam ketentuan dan regulasi yang berlaku di Indonesia. Pada praktiknya, Perseroan telah membuat Instalasi Pengolahan Air Limbah (IPAL) sebagai wadah pengelolaan limbah B3 dan untuk mengurangi dampak negatif limbah B3 bagi lingkungan. Selain itu, IPAL bertujuan untuk mengurangi dampak limbah cair yang dihasilkan oleh proses pelapisan logam (phosphating dan electroplating) serta kegiatan domestik lainnya.
Perseroan memiliki 2 (dua) instalasi IPAL, di mana IPAL 1 (Surface Treatment) berfungsi untuk mengolah air buangan dari proses pelapisan logam dan IPAL 2 (Aeration Ponds) digunakan untuk mengolah air buangan kegiatan domestik.
